Abstract (sommario):

Several Gram-negative-staining, facultatively anaerobic bacterial isolates were obtained from Eucalyptus seedlings showing symptoms of bacterial blight and dieback in Colombia, Rwanda and South Africa. Partial 16S rRNA gene sequencing, together with partial gyrB sequencing, placed the isolates in the genus Pantoea and indicated that they constituted three novel species. Multilocus sequence analysis (MLSA) based on partial sequences of gyrB, rpoB, infB and atpD revealed Pantoea dispersa , Pantoea eucrina and Pantoea cypripedii as their closest phylogenetic relatives. DNA–DNA hybridization studies confirmed the classification of the new isolates as three novel species and phenotypic tests allowed them to be differentiated from their closest phylogenetic neighbours. The names Pantoea rodasii sp. nov. [type strain LMG 26273T = BD 943T (deposited with the Plant Pathogenic and Plant Protecting Bacteria Collection, South Africa) = BCC 581T (deposited with the Bacterial Culture Collection, Forestry and Agricultural Institute, South Africa)], Pantoea rwandensis sp. nov. (type strain LMG 26275T = BD 944T = BCC 571T) and Pantoea wallisii sp. nov. (type strain LMG 26277T = BD 946T = BCC 682T) are proposed.

Abstract (sommario):

The production of quorum-sensing-related signal molecules (QSRMs) among culturable bacteria comprising the community on wheat heads was investigated. The taxonomic position of 186 bacterial isolates obtained from ten heads was inferred based on 16S rRNA gene sequences, and their QSRM production was determined using two bioreporter strains of N-acylhomoserine lactones. Approximately 33% of isolates produced QSRMs, though the proportion of QSRM-producing isolates on a wheat head was significantly negatively correlated with population size. Most of the producing isolates were Pantoea species, most commonly Pantoea ananatis. Furthermore, the proportion of Pantoea ananatis that produced QSRMs was significantly negatively correlated with the number of bacterial genera (community richness) on each head. Finally, community richness was positively correlated with population size. Qualitative analysis using thin-layer-chromatography revealed that the QSRMs of Pantoea isolates were composed of at least two compounds. This is the first report indicating that Pantoea ananatis isolates inhabiting wheat heads are capable of producing QSRMs. QSRM production by Pantoea spp. may contribute to the predominance of this genus on wheat heads, particularly at relatively low population densities and community diversity.Key words: quorum sensing, signal molecule, epiphyte, wheat head, Pantoea spp.

Abstract (sommario):

Five Gram-negative, facultatively anaerobic, non-spore-forming, coccoid rod-shaped bacterial isolates were obtained from infant formula and an infant formula production environment and were investigated by use of a polyphasic taxonomic study. Biochemical tests and partial rpoB gene sequence analysis of the five isolates revealed that they formed two distinct groups in the family Enterobacteriaceae, closely related to several species of the genera Pantoea and Erwinia, which indicated a phylogenetic position within the genus Pantoea or the genus Erwinia. Multilocus sequence analysis of concatenated partial atpD, gyrB, infB and rpoB gene sequences of two of the isolates suggested that they represented two novel species of the genus Pantoea, phylogenetically related most closely to Pantoea septica. The five isolates had general characteristics consistent with those of the genus Pantoea, and DNA–DNA hybridizations between two representatives and the type strains of their phylogenetically closest relatives based on comparative 16S rRNA gene sequence analysis showed that the isolates represented two novel genospecies. These two genospecies could be differentiated from each other based on fermentation of galacturonate, sorbitol and potassium 5-ketogluconate. They could be differentiated from phylogenetically related Pantoea species based on their ability to ferment lactose and to utilize β-gentiobiose and raffinose, their inability to ferment or utilize d-arabitol, and their inability to produce indole. On the basis of the results obtained, the five isolates are considered to represent two novel species of the genus Pantoea, for which the names Pantoea gaviniae sp. nov. (type strain A18/07T =LMG 25382T =DSM 22758T) and Pantoea calida sp. nov. (type strain 1400/07T =LMG 25383T =DSM 22759T) are proposed.

Abstract (sommario):

Bacterial strains belonging to DNA hybridization groups (HG) II, IV and V, in the Erwinia herbicola–Enterobacter agglomerans complex, of Brenner et al. [Int J Syst Bacteriol 34 (1984), 45–55] were suggested previously to belong to the genus Pantoea, but have never been formally described and classified. Additionally, it has been shown in several studies that Pectobacterium cypripedii is more closely related to species of Pantoea than to those of Pectobacterium. In this study, the phylogenetic positions of Brenner's DNA HG II, IV and V and Pectobacterium cypripedii were re-examined by both 16S rRNA gene sequencing and multilocus sequence analyses (MLSA) based on the gyrB, rpoB, atpD and infB genes. The analyses revealed that DNA HG II, IV and V and Pectobacterium cypripedii form five separate branches within the genus Pantoea (strains from HG V were split into two branches). DNA–DNA hybridization data further confirmed that DNA HG II, IV and V constitute four separate species. Pectobacterium cypripedii was shown to be a close phylogenetic relative of Pantoea dispersa and DNA HG IV by both 16S rRNA gene sequence and MLSA analyses. Biochemical analyses performed on strains from DNA HG II, IV and V and Pectobacterium cypripedii confirmed their taxonomic position within the genus Pantoea and revealed phenotypic characteristics that allow the differentiation of these species from each other and from their closest phylogenetic neighbours. It is proposed to emend the description of the genus Pantoea and to describe Pantoea septica sp. nov. for DNA HG II (type strain LMG 5345T =BD 874T =CDC 3123-70T), Pantoea eucrina sp. nov. for DNA HG IV (type strain LMG 2781T =BD 872T =CDC 1741-71T =LMG 5346T), Pantoea brenneri sp. nov. for strains of DNA HG V excluding LMG 24534 (type strain LMG 5343T =BD 873T =CDC 3482-71T) and Pantoea conspicua sp. nov. for the remaining strain of DNA HG V (type strain LMG 24534T =BD 805T =CDC 3527-71T) and to transfer Pectobacterium cypripedii to the genus as Pantoea cypripedii comb. nov. (type strain LMG 2657T =ATCC 29267T =DSM 3873T =LMG 2655T).

Abstract (sommario):

Concentrations of Colony Forming Units (CFU) were determined for two entomopathogenic bacteria (Pantoea agglomerans and Bacillus cereus), at the egg, larval, pupal, and adult stages of agriculturally important Phyllophaga and Cyclocephala white grubs, which were collected in five agroecosystems in Costa Rica. L2 and L3 larvae of Phyllophaga elenans collected in all regions where the study was conducted were extensive carriers of Pantoea agglomerans and Bacillus cereu. L2 and L3 larvae of Phyllophaga obsoleta, Phyllophaga menetriesi, Cyclocephala sanguinicollis and Cyclocephala castaniella found in the Central Valley and Central Pacific regions were carriers of Pantoea agglomerans and Bacillus cereus bacteria. In 60% to 90% of larvae in all white grub varieties studied, Pantoea agglomerans showed greater concentrations of CFU than Bacillus cereu, which showed the lowest CFU concentration. Egg, pupal, and adult mortality in all Phyllophaga species was due to Pantoea agglomerans in 62%, 80% and 22.5% of the cases, respectively. A possible antagonistic interaction between Pantoea agglomerans and Bacillus cereus is also discussed. In general, it was noted that light and larval manipulation were the main stress factors affecting these scarabids.

Abstract (sommario):

Eight yellow-pigmented, Gram-negative, rod-shaped, oxidase-negative, motile, facultatively anaerobic bacteria were isolated from onion seed in South Africa and from an onion plant exhibiting centre rot symptoms in the USA. The isolates were assigned to the genus Pantoea on the basis of phenotypic and biochemical tests. 16S rRNA gene sequence analysis and multilocus sequence analysis (MLSA), based on gyrB, rpoB, infB and atpD sequences, confirmed the allocation of the isolates to the genus Pantoea. MLSA further indicated that the isolates represented a novel species, which was phylogenetically most closely related to Pantoea ananatis and Pantoea stewartii. Amplified fragment length polymorphism analysis also placed the isolates into a cluster separate from P. ananatis and P. stewartii. Compared with type strains of species of the genus Pantoea that showed >97 % 16S rRNA gene sequence similarity with strain BD 390T, the isolates exhibited 11–55 % whole-genome DNA–DNA relatedness, which confirmed the classification of the isolates in a novel species. The most useful phenotypic characteristics for the differentiation of the isolates from their closest phylogenetic neighbours are production of acid from amygdalin and utilization of adonitol and sorbitol. A novel species, Pantoea allii sp. nov., is proposed, with type strain BD 390T ( = LMG 24248T).

Abstract (sommario):

A Gram-negative, facultatively anaerobic strain was isolated from black tea. On the basis of 16S rRNA gene sequence similarity comparisons, strain QC88-366T was grouped into the genus Pantoea, being related most closely to the type strains of Pantoea gaviniae (98.5 %) and Pantoea calida (98.3 %); sequence similarities were ≤ 97.0 % to the type strains of other species of the genus Pantoea. Multilocus sequence analysis based on partial sequences of the gyrB, rpoB, infB and atpD genes also revealed P. gaviniae and P. calida as the closest phylogenetic relatives. The fatty acid profile showed the major fatty acids of strain QC88-366T were C16 : 0, C16 : 1 and C18 : 1, the same as those of its closest related species. However, the ratio of C16 : 1, C17 : 0 cyclo, C18 : 1 and C18 : 2 differed slightly compared with those of the related neighbours. In addition, the results of physiological and biochemical tests also allowed the phenotypic differentiation of strain QC88-366T from its closest phylogenetic neighbours. The G+C content of the DNA was 57.2 mol%. Strain QC88-366T therefore represents a novel species of the genus Pantoea, for which the name Pantoea theicola sp. nov. is proposed. The type strain is QC88-366T ( = DSM 29212T = NBRC 110557T).

Abstract (sommario):

Purpose Pantoea species are pigmented, Gram-negative rods belonging to the Enterobacterales order. They are considered rare, opportunistic pathogens and are mostly implicated in nosocomial outbreaks affecting neonates and immunocompromised patients. The aim of this study was to describe the prevalence and antibiotic susceptibility of Pantoea species during a 12-year period. Materials and methods This retrospective study was carried out using microbiological data collected between January 1, 2006 and December 31, 2017. Patients’ data such as age, sex, inpatient/outpatient status, and empiric antibiotic therapy were also collected. Antimicrobial susceptibility testing was performed using E-tests; the interpretation was based on European Committee on Antimicrobial Susceptibility Testing breakpoints for Enterobacterales. Results Seventy individual Pantoea spp. isolates were identified; the most frequently isolated species was Pantoea agglomerans. Most isolates were susceptible to relevant antibiotics. In 61 out of 68 patients, ampicillin was the empirically administered antibiotic. The highest levels of resistance were to amoxicillin–clavulanic acid and ampicillin. No extended spectrum beta-lactamase-positive isolate was detected. Conclusions There is a scarcity of data available on the susceptibility patterns of Pantoea species, but our results correspond to what we could find in the literature. The development of multidrug-resistant (MDR) Gram-negative bacteria is a grave concern, and the development of MDR Pantoea spp. may be expected in the future.

Abstract (sommario):

Phytate-hydrolyzing bacteria Pantoea sp. 3.1, 3.2, 3.5.2, 3.6.1 and Bacillus ginsengihumi M2.11 were previously isolated from the soil samples of the Republic of Tatarstan. The effect of cultivation conditions on the growth dynamics as well as antimicrobial activity was determined. All four Pantoea strains showed optimum growth at 26 ºC and 28 ºC and pH 6.0-7.0. The optimum conditions for the growth of B. ginsengihumi M2.11 strain was determined to be 26 ºC, 28 ºC and 37 ºC and alkaline pH 7 and 8. Salt concentration in the range of 0 to 1000 mM did not significantly affect the growth of the strains. Antagonistic activity of Pantoea sp. 3.5.2 was studied against phytopathogenic micromycetes, identified as Alternaria alternata and Bipolaris sorokiniana. In the presence of bacterial isolate growth of A. alternata was inhibited by 57% and growth of B. sorokiniana – by 85%. Minor growth inhibition by Pantoea sp. 3.5.2 of gram-negative bacteria from Enterobacteriaceae family was observed. The presence of fungicidal activity in the Pantoea strain together with its ability to hydrolyze soil phytates and overcome abiotic stress factors in soil can possibly serve as the basis for the new fungicide of microbial origin.

Abstract (sommario):

Six isolates recovered from coffee seeds giving off a potato-like flavour were studied. Gene sequencing (rrs and rpoB) showed they belong to the genus Pantoea . By DNA–DNA hybridization, the isolates constituted a genomic species with less than 17 % relatedness to 96 strains representing enterobacterial species. Multilocus sequence analysis (gyrB, rpoB, atpD and infB genes) showed the isolates to represent a discrete species of the genus Pantoea . Nutritional versatility of the novel species was poor. The novel species is proposed as Pantoea coffeiphila sp.nov. and its type strain is Ca04T ( = CIP 110718T = DSM 28482T).

Abstract (sommario):

Pantoea dispersa W18, isolated from contaminated soil, was found to exert antimicrobial activity against Mycobacterium species, including Mycobacterium tuberculosis, an important human pathogen. Here, the anti-mycobacterial compound produced by Pantoea dispersa W18 was purified by a combination of hydrophobic interaction chromatography, cation exchange chromatography, and reverse phase HPLC. Active compounds from Pantoea dispersa W18 were identified as a natural peptide named pantocin wh-1 with a 1927 Da molecular weight. The primary structure of this compound was detected by N-terminal amino acid sequencing. The amino acid sequence of pantocin wh-1 consisted of 16 amino acid residues with a cyclic structure. The pantocin wh-1 could be inactivated by protease K, but was heat stable and unaffected by pH (2–12). However, the activity was not completely inactivated by trypsin and pepsin. This is the first report of a cyclic polypeptide purified from a strain of Pantoea dispersa.

Abstract (sommario):

The germination of surface-sterilized maize kernels under aseptic conditions proved to be a suitable method for isolation of kernel-associated bacterial endophytes. Bacterial strains identified by partial 16S rRNA gene sequencing as Pantoea sp., Microbacterium sp., Frigoribacterium sp., Bacillus sp., Paenibacillus sp., and Sphingomonas sp. were isolated from kernels of 4 different maize cultivars. Genus Pantoea was associated with a specific maize cultivar. The kernels of this cultivar were often overgrown with the fungus Lecanicillium aphanocladii ; however, those exhibiting Pantoea growth were never colonized with it. Furthermore, the isolated bacterium strain inhibited fungal growth in vitro.

Abstract (sommario):

Pantoea citrea, Pantoea punctata and Pantoea terrea were described for strains isolated from fruit and soil originating in Japan. These three ‘Japanese’ species have been shown to be phylogenetically distant from other species of the genus Pantoea. It has been observed previously that, using multilocus sequence analysis (MLSA), the ‘Japanese’ species consistently formed a distinct clade with an extended branch length, casting doubt on the inclusion of these species within the genus Pantoea. Furthermore, the ‘Japanese’ species are closely related to Tatumella ptyseos, strains of which originate from human clinical specimens. DNA–DNA hybridization and phenotypic tests confirmed the observed phylogenetic distance of P. citrea, P. punctata and P. terrea from the genus Pantoea and the affiliation of these species with Tatumella. In addition, strains causing pink disease of pineapple, identified previously as P. citrea, were shown to represent a separate species by using 16S rRNA gene sequence analysis, and MLSA and DNA–DNA hybridization data. The name Tatumella morbirosei sp. nov. with the type strain LMG 23360T (=BD 878T=NCPPB 4036T=CMC6T) is proposed to accommodate these strains. The new combinations Tatumella citrea (Kageyama et al. 1992) comb. nov.

Abstract (sommario):

A total of 30 bacterial isolates were isolated from soil, rhizoplane, and internal tissue of oil palm roots. The isolates were qualitatively tested for their potential to fix N2, solubilize inorganic P and K, and produce phytohormone indole-3-acetic acid. Of the 30 isolates, six isolates were able to exhibit multiple beneficial traits. All six isolates were then identified based on fatty acid methyl esters profile as Escherichia coli strain EX2, Serratia sp. strain EN1, Pantoea ananatis strain EN3, Bacillus sp. strain EN5, Pantoea ananatis strain EN8 and Pantoea sp. strain EN9. Subsequently, all shortlisted isolates were evaluated for plant growth-promoting potential by using shallot as a test plant. The plant test showed no significant difference (p>0.05) between inoculated and uninoculated plants except for Pantoea sp. strain EN9 inoculation which increased significantly (p<0.05) total root length over uninoculated control. Host specificity and IAA capacity of the isolates may be among the important factors affecting their effectiveness in plant growth promotion. J Bangladesh Agril Univ 17(3): 344–348, 2019

Abstract (sommario):

An unreported disease of sudangrass (Sorghum sudanense) was observed in commercial fields in Imperial Valley of California. Symptoms included light-colored necrotic streaks, and white or tan irregular blotches, often associated with reddish purple to dark brown margins. Pantoea ananas was consistently isolated from the blotches with reddish margins, while Pantoea stewartii or mixtures of both species were isolated from necrotic streaks without reddish margins. Fourteen seed samples harvested in different locations were assayed and found to be 0.0 to 3.6% infested with P. ananas. Seed transmission may be a means by which the pathogen is introduced. Symptoms in inoculated plants appeared as early as 2 and as late as 20 days after inoculation, depending on the inoculum level, methods of inoculation, temperature, and available moisture. The initial symptoms caused by inoculations with both bacteria were similar, but as symptoms progressed, P. ananas was associated with white streaks or irregular necrotic blotches often surrounded by a reddish or purplish hue. P. stewartii was associated with light-colored necrotic streaks. A synergistic or antagonistic relationship was not observed between the two pathogens in co-inoculations. In host range studies, both bacteria caused disease on sorghum and sudangrass at similar levels of severity. P. ananas was also pathogenic on corn and oat. P. stewartii from sudangrass was pathogenic on corn but did not cause wilting that was observed with Stewart's wilt strains of P. stewartii from corn. The sudangrass strains of P. stewartii also infected oat and triticale, while the Stewart's wilt strains did not. Both P. ananas and P. stewartii from sudangrass grew at relatively high temperatures (43 and 37°C, respectively) and caused disease at elevated temperatures and conditions of relative humidity similar to those in the Imperial Valley during late summer when epidemics of the disease were common.

Abstract (sommario):

Digitaria ischaemum (Schreb.) Schreb. ex Muhl. and Poa annua L. are competitive, early successional species which are usually considered weeds in agricultural and turfgrass systems. Bacteria and fungi associated with D. ischaemum and P. annua seed may contribute to their competitiveness by antagonizing competitor forbs, and were studied in axenic culture. Pantoea spp. were the most common bacterial isolate of D. ischaemum seed, while Epicoccum and Curvularia spp. were common fungal isolates. A variety of species were collected from non-surface sterilized P. annua. Certain Pantoea spp. isolates were antagonistic to competitor forbs Taraxacum officinale, Trifolium repens. All bacterial isolates that affected T. officinale mortality were isolated from D. ischaemum seed while none of the P. annua isolates affected mortality. Two selected bacterial isolates identified as Pantoea ananatis were evaluated further on D. ischaemum, T. repens (a competitor forb) and P. annua (a competitor grass) alone and in combination with a Curvularia sp. fungus. These bacteria alone caused >65% T. repens seedling mortality but did not affect P. annua seedling mortality. These experiments demonstrate that Pantoea ananatis associated with D. ischaemum seeds is antagonistic to competitor forbs in axenic culture. The weedy character of D. ischaemum could at least in part stem from the possession of bacteria that are antagonistic to competitor species.

Abstract (sommario):

ABSTRACT Pantoea stewartii subsp. stewartii is the causative agent of Stewart's wilt, a bacterial disease transmitted by the corn flea beetle mainly to sweet corn (Zea mays). In many countries, it is classified as a quarantine organism and must be differentiated from other yellow enteric bacteria frequently occurring with corn. We have created novel primers from the pstS-glmS region of P. stewartii for use in conventional PCR (cPCR) and quantitative PCR (qPCR). To facilitate rapid diagnosis, we applied matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) analysis. Using whole-cell protein extracts, profiles were generated with a Bruker microflex machine, and the bacteria classified. P. stewartii strains were clearly distinguished from strains of Pantoea agglomerans, Pantoea dispersa, and Pantoea ananatis. Dendrogram analysis of the protein profiles confirmed the score values and showed the formation of separate clades for each species. The identification achieved by MALDI-TOF MS analysis agrees with the diagnosis by specific PCR primers. The combination of both methods allows a rapid and simple identification of the corn pathogen. P. stewartii subsp. stewartii and P. stewartii subsp. indologenes are highly related and can be distinguished not only by virulence assays and indole tests but also by a characteristic pattern in the nucleotide sequence of recA.

Abstract (sommario):

One hundred twenty-four bacterial isolates originating from sweet corn or corn flea beetles in the northeastern, midwestern, and mid-Atlantic United States were verified as Erwinia stewartii (Pantoea stewartii subsp. stewartii) and characterized phenotypically by their respiratory response to 91 carbon sources. The unweighted pair group method of averages (UPGMA) was used to construct a dendrogram that revealed homogeneous metabolic profiles at 93% similarity. Two-thirds of the isolates formed 18 separate groups, each sharing the same metabolic profile. One-third of the isolates had distinct metabolic profiles. Most groups shared either isolation source, geographical location, and/or year of isolation. Members of some groups persisted through time and had been isolated from diverse geographical locations. Four representative strains of the proposed Pantoea stewartii subsp. indologenes were also characterized; their metabolic profiles were most similar to those of Erwinia herbicola (Pantoea agglomerans).

Abstract (sommario):

The king oyster mushroom, Pleurotus eryngii, has become a popular crop because of its unique flavor and texture and is cultivated in many areas in Korea. In 2003, symptoms of water-soaked lesions and soft rot in the stipes and pileus of cultivated P. eryngii was observed in Jinju, Korea. Diseased tissue was plated on nutrient media. Dominate colonies were yellow, convex, circular with smooth margins, and had a shiny texture. Computer analysis of the data gathered, using the API kit (50CHE, bioMérieux, Marcy-l'Etoile, France), showed that the strain belongs to the Enterobacteriaceae. Although the API system did not give an exact identification, the metabolic profile of the bacterial strain closely resembled the database profile of Pantoea sp. (positive for acid production from the fermentation of d-fructose, d-galactose, d-glucose, d-trehalose, and d-ribose and negative for oxidase, urease, pectate, and thiosulfate). The 16S rDNA sequence of the bacterium was determined (GenBank Accession No. AY530796). When compared with those in GenBank, the bacterium was determined to belong to the Enterobacteriaceae family of the Gammaproteobacteria, and the highest degree of sequence similarity was found to be with Pantoea ananatis strain BD 588 (97.4%) and Pantoea ananatis strain Pna 97-1 (97.3%). In the phylogenetic tree, the bacterium clearly related to the Pantoea lineage, as evidenced by the high bootstrap value. A BLAST search with 16S rDNA sequence of the bacterium supported the API results that the isolate belongs to a species of Pantoea. Pathogenicity tests of this new Pantoea isolate were carried out with bacterial suspensions (approximately 1 × 106 CFU/ml) that were grown for 24 h in Luria-Bertani broth cultures. These were used to inoculate directly on the mycelia of P. eryngii that had been cultivated for 35 days in a plastic bottle. The water and broth were also inoculated to another set of bottles as a control experiment. Inoculated bottles were incubated in a cultivation room at 16 to 17°C with relative humidity between 80 and 95%. Early symptoms of the disease included a dark brown water drop that developed on hypha and primordium of the mushrooms after 5 to 7 days. After 13 days, water-soaked lesions developed on the stipes and pileus, and the normal growth of the mushrooms was inhibited. An offensive odor then developed along with a severe soft rot that was similar to the disease symptoms observed under natural conditions. Mushrooms in control bottles did not develop symptoms. Koch's postulates were fulfilled by isolating bacteria from typical lesions from inoculated mushrooms that were identical to the inoculated strain in colony morphology and biochemical characteristics. Pantoea ananatis was first reported as a pathogen of pineapple fruit causing brown rot (3). Several bacterial diseases, such as brown blotch on cultivated mushrooms by Pseudomonas tolaasii (2) and bacterial soft rot on winter mushroom by Erwinia carotovora subsp. Carotovora, causing severe damage to mushrooms are known (1). However, no Pantoea sp. induced disease of edible mushroom has been previously reported. To our knowledge, this is the first report of soft rot disease on P. eryngii caused by Pantoea sp. References: (1) H. Okamoto et al. Ann. Phytopathol. Soc. Jpn. 65:460. 1999. (2) S. G. Paine. Ann.

Abstract (sommario):

Background: Cadmium (Cd), which is a deadly heavy metal of work-related and environmental concern, has been recognized as a substance that is teratogenic and carcinogenic for humans. Therefore, the need to develop low-cost adsorbents to remove heavy metals from aqueous solution has greatly increased. Adsorbents such as Pantoea agglomerans biomass have been used. Aims: We investigated the biotechnological potential of Pantoea agglomerans for the biosorption of cadmium from aqueous solution. Patients and Methods: Pantoea agglomerans UCP1320 isolated from the effluent of a laundry industry was used to remove cadmium from aqueous solutions. Two approaches were compared using active or thermally inactivated biomass. Three different cadmium concentrations of 1, 10 and 100 ppm were used under constant stirring at temperatures of 25°C and 35°C as was pH of 3.0, 5.0 and 7.0. Variable incubation times of 1, 6, and 24h were also studied. Results: The results showed that the temperature did not influence the uptake of metal by living cells nor by inactive bacterial biomass. However, increasing the pH had a positive effect on removing intermediate concentrations of cadmium. Low concentrations of cadmium were completely removed by both live and inactive biomass. Conclusion: Pantoea agglomerans biomass was shown to have a promising performance for the biotechnological removal of cadmium which had been dissolved in aqueous solution.

Abstract (sommario):

Fourteen distinct bacterial clones were isolated from surface-sterilized shoot tips (~1 cm) of papaya (Carica papaya L. ‘Surya’) planted on Murashige and Skoog (MS)-based papaya culture medium (23/50 nos.) during the 2–4 week period following in vitro culturing. These isolates were ascribed to six Gram-negative genera, namely Pantoea ( P. ananatis ), Enterobacter ( E. cloacae ), Brevundimonas ( B. aurantiaca ), Sphingomonas , Methylobacterium ( M. rhodesianum ), and Agrobacterium ( A. tumefaciens ) or two Gram-positive genera, Microbacterium ( M. esteraromaticum ) and Bacillus ( B. benzoevorans ) based on 16S rDNA sequence analysis. Pantoea ananatis was the most frequently isolated organism (70% of the cultures) followed by B. benzoevorans (13%), while others were isolated from single stocks. Bacteria-harboring in vitro cultures often showed a single organism. Pantoea, Enterobacter, and Agrobacterium spp. grew actively on MS-based normal papaya medium, while Microbacterium, Brevundimonas, Bacillus, Sphingomonas, and Methylobacterium spp. failed to grow in the absence of host tissue. Supplying MS medium with tissue extract enhanced the growth of all the organisms in a dose-dependent manner, indicating reliance of the endophyte on its host. Inoculation of papaya seeds with the endophytes (20 h at OD550 = 0.5) led to delayed germination or slow seedling growth initially. However, the inhibition was overcome by 3 months and the seedlings inoculated with Pantoea, Microbacterium, or Sphingomonas spp. displayed significantly better root and shoot growths.

Abstract (sommario):

Introduction. Pantoea agglomerans, an anaerobic Gram-negative bacillus, is a rare cause of opportunistic infections affecting premature infants to seniors. We present a 34-year-old man who was presented for the management of diabetic ketoacidosis and developed Pantoea agglomerans bacteremia after one week of hospitalization. Case Presentation. A 34-year-old African-American male with uncontrolled diabetes mellitus type I and recurrent skin infections was admitted with diabetic ketoacidosis. He had left upper extremity abscess, preliminary wound cultures were positive for Gram-positive cocci, and an initial set of blood cultures were negative. He was started empirically on vancomycin. One week after admission, he started having chills followed by a recurrent increase in body temperature to 102 degrees Fahrenheit. The wound was healing, without active infection. Chest X-ray and CT scan of abdomen and pelvis to rule out infection were negative. Repeat blood cultures showed P. agglomerans in both the tubes. The patient was successfully treated with intravenous ceftriaxone, and he recovered fully without any complication. Discussion. Pantoea agglomerans is a bacteria associated with plants; however, it can infect humans and vertebrate animals. The outcome seems favourable with the institution of appropriate antibiotics even in immunocompromised patients.

Abstract (sommario):

The current study aimed to determine the diversity of culturable endophytic bacteria associated with horseradish (Armoracia rusticana G. Gaertn., B. Mey. & Scherb.) grown in Chatkal Biosphere Reserve of Uzbekistan and their antimicrobial potentials. The bacteria were isolated from plant leaves and root tissues using culture-dependent techniques. The 16S rRNA sequences similarities of endophytic bacteria isolated from A. rusticana showed that isolates belong to species Paenibacillus, Raoultella, Stenotrophomonas, Pseudomonas, Serratia, Microbacterium, Enterobacter, Achromobacter, Brevibacterium, Pantoea, and Erwinia. The isolated endophytic bacteria Stenotrophomonas maltophilia KRT1, Serratia ficaria KRT5, and Pantoea agglomerans KLT4 possess antimicrobial activities against human pathogenic bacteria Staphylococcus aureus, Escherichia coli, and Candida albicans. The endophytic bacteria Paenibacillus typhae KRN1, Stenotrophomonas maltophilia KRT1, Pseudomonas kilonensis KRT11, Pseudomonas umsongensis KRT21, Brevibacterium frigoritolerans KLT2 and Pantoea agglomerans KLT4 inhibited phytopathogenic fungi Rhizoctonia solani, Fusarium culmorum, and F. solani. These findings indicate that plant endophytic bacteria with antimicrobial activity could be a source for producing agriculturally and pharmaceutically important antimicrobial compounds.

Abstract (sommario):

Pseudomonas fluorescens A506 and Pantoea agglomerans strains Eh252 and C9-1 are biological control agents that suppress fire blight, an important disease of pear and apple caused by the bacterium Erwinia amylovora. Pseudomonas fluorescens strain A506 suppresses disease largely through competitive exclusion of E. amylovora on surfaces of blossoms, the primary infection court, whereas Pantoea agglomerans strains Eh252 and C9-1 produce antibiotics that are toxic to E. amylovora. In this study, an extracellular protease produced by A506 is characterized and evaluated for its capacity to inactivate the antibiotics produced by the strains of Pantoea agglomerans. Activity of the extracellular protease was optimal at pH 9 and inhibited by zinc- or calcium-chelators, indicating that the protease is an alkaline metalloprotease. In an agar plate bioassay, partially purified extracellular protease inactivated the antibiotics mccEh252 and herbicolin O, which are produced by Pantoea agglomerans strains Eh252 and C9-1, respectively. Derivatives of A506 deficient in extracellular protease production were obtained by transposon mutagenesis, and the aprX gene encoding the protease was cloned and sequenced. Strain A506 inactivated mccEh252 and herbicolin O in agar plate bioassays, whereas the aprX mutant did not inactivate the antibiotics. Both A506 and the aprX mutant were insensitive to antibiosis by C9-1 and Eh252; thus, the protease was not required to protect A506 from antibiosis. These data highlight a previously unknown role of the extracellular protease produced by Pseudomonas fluorescens A506 in interactions among plant-associated microbes.

Abstract (sommario):

A novel bacterial strain, 29Y89BT, was isolated from a faecal sample of a healthy human subject. Cells were Gram-stain-negative, motile, non-spore-forming and rod-shaped. Strain 29Y89BT formed cream-coloured colonies 2 mm in diameter on trypticase soy agar and showed optimum growth at 35 °C. Strain 29Y89BT showed highest 16S rRNA gene sequence similarity to Pantoea gaviniae A18/07T (98.4 %) followed by Pantoea calida 1400/07T (97.2 %). Multi-locus sequence analysis using atpD (ATP synthase β subunit), gyrB (DNA gyrase), infB (initiation translation factor 2) and rpoB (RNA polymerase β subunit) genes also supported the result of 16S rRNA gene sequence based phylogeny. Strain 29Y89BT showed 62 and 40.7 % DNA–DNA relatedness with P. calida DSM 22759T and P. gaviniae DSM 22758T. Strain 29Y89BT contained C17 : 0 cyclo, C19 : 0 cyclo ω8c, C16 : 0, C14 : 0 and C12 : 0 as predominant fatty acids. In addition, strain 29Y89BT showed physiological and phenotypic differences from its closest relatives P. gaviniae DSM 22758T and P. calida DSM 22759T. The polar lipid profile mainly comprised phospholipids. The DNA G+C content was 59.1 mol%. Thus, based on the findings of the current study, strain 29Y89BT showed clear delineations from its closest relatives P. gaviniae DSM 22758T and P. calida DSM 22759T, and is thus considered to represent a novel species of the genus Pantoea, for which the name Pantoea intestinalis sp. nov. is proposed. The type strain is 29Y89BT ( = DSM 28113T = MCC 2554T).

Abstract (sommario):

With the growth of the planet’s population and the depletion of mineral resources, the increase in crop yields, the search for environmentally friendly technologies, the use of enzymes and siderophores of bacterial origin, or the use of bacterial strains t hat promote plant growth (PGP ) are becoming more urgent. Was found in a strain of bacteria Pantoea brenneri AS3 produced of siderophore (82.05 μM) accounted for 28 hour culture. The strain Pantoea brenneri AS3 demonstrate antagonistic activity against all studied phytopathogenic fungi. Antagonistic activity was measured on the basis of growth inhibition of micromycetes colony compared to the control plates. The highest antagonistic activities of both strains were observed against F. solani (87%).
