Abstract (sommario):
Four strains (JA310T, JA531T, JA447 and JA490) of red to reddish brown pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from soil and freshwater sediment samples from different geographical regions of India. All strains contained bacteriochlorophyll a and carotenoids of the spirilloxanthin series. The major cellular fatty acid of strains JA310T and JA531T was C18 : 1ω7c, the quinone was Q-10 and polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an aminohopanoid and an unidentified aminolipid. Phylogenetic analysis based on 16S rRNA gene sequences showed that all strains clustered with species of the genus Rhodopseudomonas in the class Alphaproteobacteria . Strains JA531T, JA447 and JA490 were genotypically (>80 % related based on DNA–DNA hybridization) and phenotypically closely related to each other and the three strains were distinct from strain JA310T (33 % related). Furthermore, all four strains had less than 48 % relatedness (DNA–DNA hybridization) with type strains of members of the genus Rhodopseudomonas , i.e. Rhodopseudomonas palustris ATCC 17001T, Rhodopseudomonas faecalis JCM 11668T and Rhodopseudomonas rhenobacensis DSM 12706T. The genomic DNA G+C contents of strains JA310T and JA531T were 63.8 and 62.4 mol%, respectively. On the basis of phenotypic, chemotaxonomic and molecular genetic evidence, it is proposed that strains JA310T ( = NBRC 106083T = KCTC 5839T) and JA531T ( = NBRC 107575T = KCTC 5841T) be classified as the type strains of two novel species of the genus Rhodopseudomonas , Rhodopseudomonas parapalustris sp. nov. and Rhodopseudomonas harwoodiae sp. nov., respectively. In addition, we propose that strain DSM 123T ( = NBRC 100419T) represents a novel species, Rhodopseudomonas pseudopalustris sp. nov., since this strain differs genotypically and phenotypically from R. palustris ATCC 17001T and other members of the genus Rhodopseudomonas . An emended description of R. palustris is also provided.

Abstract (sommario):
In this study, we isolated a strain of photosynthetic bacteria from landscape water located in Southwest University, Chongqing, China, and named it Smobiisys501. Smobiisys501 was Rhodopseudomonas sp. according to its cell morphological properties and absorption spectrum analysis of living cells. The analysis of the 16S rDNA amplification sequence with specific primers of photosynthetic bacteria showed that the homology between Smobiisys501 and Rhodopseudomonas sp. was 100%, and the alignment results of protein sequences of the bacterial chlorophyll Y subunit showed that Smobiisys501 and Rhodopseudomonas palustris were the most similar, with a similarity of more than 92%. However, Smobiisys501 could not utilize glucose and mannitol as a carbon source and had a low fatty acid content, which were different from the related strains of the genus Rhodopseudomonas. Moreover, the DNA-DNA relatedness was only 42.2 ± 3.3% between Smobiisys501 and the closest strain Rhodopseudomonas palustris. Smobiisys501 grew optimally at 30 °C and pH 7.0 in the presence of yeast extract, and it could efficiently remove ammonium (99.67% removal efficiency) from synthetic ammonium wastewater. All the results indicated that Smobiisys501 was a novel species of Rhodopseudomonas, with the ability to remove ammonium.

Abstract (sommario):
Two strains (JA575T and JA576T) of orange- to pink-pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from paddy soils. Both strains contained bacteriochlorophyll a and carotenoids of spirilloxanthin series. Both strains had C18 : 1ω7c as the major cellular fatty acid, ubiquinone-10 (Q10) as the main quinone, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine as polar lipids. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that both strains clustered with species of the genus Rhodopseudomonas in the class Alphaproteobacteria . Strains JA575T and JA576T were genotypically (<35 % DNA–DNA relatedness) and phenotypically distinct from each other. Further, both strains showed less than 48 % DNA–DNA relatedness with the type strains of all recognized species of the genus Rhodopseudomonas . The molecular evidence is supported by phenotypic evidence. It is proposed that strains JA575T and JA576T be classified as representing two novel species of the genus Rhodopseudomonas with the species names Rhodopseudomonas pentothenatexigens sp. nov. and Rhodopseudomonas thermotolerans sp. nov., respectively. The type strains of the proposed novel species are JA575T ( = NBRC 108862T = KCTC15143T) and JA576T ( = NBRC 108863T = KCTC 15144T), respectively.

Abstract (sommario):
The nucleotide sequence of a 2.37 kb DNA fragment derived from cloning a total DNA digest of Rhodopseudomonas capsulata sp108 was determined. The DNA codes for a beta-lactamase, a protein showing sequence similarity to the ampR protein of Enterobacter cloacae and an unidentified open reading frame. Hybridization experiments with a probe carrying DNA from within the beta-lactamase gene suggests a chromosomal location for the coding sequences in strain sp108 and in sp109, a penicillin-sensitive revertant of sp108 in which the enzyme is not inducible. A protein-sequence comparison of the deduced amino acid sequence of the Rps. capsulata beta-lactamase indicates that it is a Class A enzyme and that its sequence can be aligned with those of the characterized beta-lactamases from Staphylococcus aureus, Bacillus licheniformis and the Escherichia coli plasmid (R-TEM enzyme), with only a few insertions or deletions. The corresponding DNA sequence is, however, characteristically rhodopseudomonad, suggesting that it is not a recently transposed gene.

Abstract (sommario):
The genus Rhodopseudomonas , containing purple nonsulfur photosynthetic Proteobacteria, has a number of strains that belong to different species, although many of them are collectively called Rhodopseudomonas palustris . The type species R. palustris and closely related species are the focus of this paper. The comparison of available genome sequences indicate that the following Rhodopseudomonas species are well recognized: R. palustris (strains ATH 2.1.6T=DSM 123T=NBRC 100419T and BisB5), Rhodopseudomonas rutila (strains R1T, DSM 126, CGA009, ATH 2.1.37, Eli 1980, ATCC 17001 and TIE1), Rhodopseudomonas pentothenatexigens JA575T and Rhodopseudomonas faecalis JCM 11668T. Other strains for which genome sequences are available are distinct from these four species. Evidence is presented that R. palustris strain ATH 2.1.6T–KCM as obtained directly from the van Niel collection by one of us (T.E.M.) is identical to the DSMZ deposit DSM 123T of ATH 2.1.6T, but not to the deposit at ATCC 17001. The amino acid sequences of the cytochromes C2 and C556 from R. palustris strain ATH 2.1.6T–KCM are in complete agreement with the translated genome sequences of R. palustris DSM 123T. In addition, the 16S rRNA gene sequence of R. palustris NBRC 100419T completely matches that of strain DSM 123T. In conclusion, the type strain of R. palustris ATH 2.1.6T is correctly represented by DSM 123T and NBRC 100419T. However, the deposit at ATCC 17001 has properties that do not conform with properties of authentic R. palustris , but rather indicate that this is a strain of R. rutila . The previously suggested assignment of the type strain of R. palustris DSM 123T to the new species R. pseudopalustris was incorrect because strain DSM 123T is the authentic type strain of R. palustris .

Abstract (sommario):
ABSTRACT To assess the extent of genotypic and phenotypic diversity within species of purple nonsulfur bacteria found in aquatic sediments, a total of 128 strains were directly isolated from agar plates that had been inoculated with sediment samples from Haren and De Biesbosch in The Netherlands. All isolates were initially characterized by BOX-PCR genomic DNA fingerprinting, and 60 distinct genotypes were identified. Analyses of 16S rRNA gene sequences of representatives of each genotype showed that five and eight different phylotypes of purple nonsulfur bacteria were obtained from the Haren and De Biesbosch sites, respectively. At the Haren site, 80.5% of the clones were Rhodopseudomonas palustris, whereas Rhodoferax fermentans and Rhodopseudomonas palustris were numerically dominant at the De Biesbosch site and constituted 45.9 and 34.4% of the isolates obtained, respectively. BOX-PCR genomic fingerprints showed that there was a high level of genotypic diversity within each of these species. The genomic fingerprints of Rhodopseudomonas palustris isolates were significantly different for isolates from the two sampling sites, suggesting that certain strains may be endemic to each sampling site. Not all Rhodopseudomonas palustris isolates could degrade benzoate, a feature that has previously been thought to be characteristic of the species. There were differences in the BOX-PCR genomic fingerprints and restriction fragment length polymorphisms of benzoate-coenzyme A ligase genes and form I and form II ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) genes between benzoate-degrading and non-benzoate-degrading genotypes. The ability to distinguish these two Rhodopseudomonas palustris groups based on multiple genetic differences may reflect an incipient speciation event resulting from adaptive evolution to local environmental conditions.

Abstract (sommario):
The synthesis of polyhydroxybutyrate (PHB) by photosynthetic non-sulfur bacteria is a potential approach for producing biodegradable plastics. In this work, acetate was used as a single carbon source to study the effect on PHB formation in Rhodopseudomonas sp. cultured in a cylindrical four-liter photobioreactor under semi-continuous mode. The cultivation process is divided into a symmetrical growth phase and a PHB accumulation phase separated temporally. The symmetrical growth phase (nutrient sufficient conditions) was followed by a sulfur-limited phase to promote PHB accumulation. The main novelty is the progressive lowering of the sulfur concentration into Rhodopseudomonas culture, which was obtained by two concomitant conditions: (1) sulfur consumption during the bacterial growth and (2) semi-continuous growth strategy. This caused a progressive lowering of the sulfur concentration into Rhodopseudomonas culturedue to the sulfur-free medium used to replace 2 L of culture (50% of the total) that was withdrawn from the photobioreactor at each dilution. The PHB content ranged from 9.26% to 15.24% of cell dry weight. At the steady state phase, the average cumulative PHB was >210 mg/L. Sulfur deficiency proved to be one of the most suitable conditions to obtain high cumulative PHB in Rhodopseudomonas culture.

Abstract (sommario):
ABSTRACT The community structure of pink-colored microbial mats naturally occurring in a swine wastewater ditch was studied by culture-independent biomarker and molecular methods as well as by conventional cultivation methods. The wastewater in the ditch contained acetate and propionate as the major carbon nutrients. Thin-section electron microscopy revealed that the microbial mats were dominated by rod-shaped cells containing intracytoplasmic membranes of the lamellar type. Smaller numbers of oval cells with vesicular internal membranes were also found. Spectroscopic analyses of the cell extract from the biomats showed the presence of bacteriochlorophyll a and carotenoids of the spirilloxanthin series. Ubiquinone-10 was detected as the major quinone. A clone library of the photosynthetic gene, pufM, constructed from the bulk DNA of the biomats showed that all of the clones were derived from members of the genera Rhodobacter and Rhodopseudomonas. The dominant phototrophic bacteria from the microbial mats were isolated by cultivation methods and identified as being of the genera Rhodobacter and Rhodopseudomonas by studying 16S rRNA and pufM gene sequence information. Experiments of oxygen uptake with lower fatty acids revealed that the freshly collected microbial mats and the Rhodopseudomonas isolates had a wider spectrum of carbon utilization and a higher affinity for acetate than did the Rhodobacter isolates. These results demonstrate that the microbial mats were dominated by the purple nonsulfur bacteria of the genera Rhodobacter and Rhodopseudomonas, and the bioavailability of lower fatty acids in wastewater is a key factor allowing the formation of visible microbial mats with these phototrophs.

Abstract (sommario):
The objective of this study was to determine the effect of Rhodopseudomonas p., which isolated from domestic soil on the density of microorganism in soil, leaf and SSC in pear (Pyrus pyrifolia) fruit. The solution of Rhodopseudomonas p. was sprayed over canopy and fertigated around trunk in 12-year-old `Niitaka' pear with Y-training system. The spray and fertigation were performed 11 times at 15-day intervals from 22 Apr. to 22 Sept. with 200 times diluted solution (v/v). The width and length of treated leaf was increased by 1.4 mm and 0.9 mm compared to them of control. There was no difference in chlorophyll a content between treatments. The treatment increased SSC relatively to control by 0.7% and fruit firmness by 0.29 higher but there was no difference fruit weight. Hinter `L' value was higher by 3.5 and Hunter `a' lower by 0.2 compared to control so fruit color was more clean than control. In fertigation treatment, the density of microorganism and fluorescent bacteria in soil showed increasing tendency compared to control but the opposite in bacteria. These results suggested that the spray and fertigation of Rhodopseudomonas p. solution improve SSC and color of pear fruit.

Abstract (sommario):
Rhodopseudomonas palustris, a nonsulphur purple photosynthetic bacteria, has been extensively investigated for its metabolic versatility including ability to produce hydrogen gas from sunlight and biomass. The availability of the finished genome sequences of six R. palustris strains (BisA53, BisB18, BisB5, CGA009, HaA2 and TIE-1) combined with online bioinformatics software for integrated analysis presents new opportunities to determine the genomic basis of metabolic versatility and ecological lifestyles of the bacteria species. The purpose of this investigation was to compare the functional annotations available for multiple R. palustris genomes to identify annotations that can be further investigated for strain-specific or uniquely shared phenotypic characteristics. A total of 2,355 protein family Pfam domain annotations were clustered based on presence or absence in the six genomes. The clustering process identified groups of functional annotations including those that could be verified as strain-specific or uniquely shared phenotypes. For example, genes encoding water/glycerol transport were present in the genome sequences of strains CGA009 and BisB5, but absent in strains BisA53, BisB18, HaA2 and TIE-1. Protein structural homology modeling predicted that the two orthologous 240 aa R. palustris aquaporins have water-specific transport function. Based on observations in other microbes, the presence of aquaporin in R. palustris strains may improve freeze tolerance in natural conditions of rapid freezing such as nitrogen fixation at low temperatures where access to liquid water is a limiting factor for nitrogenase activation. In the case of adaptive loss of aquaporin genes, strains may be better adapted to survive in conditions of high-sugar content such as fermentation of biomass for biohydrogen production. Finally, web-based resources were developed to allow for interactive, user-defined selection of the relationship between protein family annotations and the R. palustris genomes.

Abstract (sommario):
Arsenic (As) is a well-known toxic metalloid found naturally and released by different industries, especially in developing countries. Purple nonsulfur bacteria (PNSB) are known for wastewater treatment and plant growth promoting abilities. As-resistant PNSB were isolated from a fish pond. Based on As-resistance and plant growth promoting attributes, 2 isolates CS2 and SS5 were selected and identified as Rhodopseudomonas palustris and Rhodopseudomonas faecalis, respectively, through 16S rRNA gene sequencing. Maximum As(V) resistance shown by R. faecalis SS5 and R. palustris CS2 was up to 150 and 100 mM, respectively. R. palustris CS2 showed highest As(V) reduction up to 62.9% (6.29±0.24 mM), while R. faecalis SS5 showed maximum As(III) oxidation up to 96% (4.8±0.32 mM), respectively. Highest auxin production was observed by R. palustris CS2 and R. faecalis SS, up to 77.18±3.7 and 76.67±2.8 μg mL−1, respectively. Effects of these PNSB were tested on the growth of Vigna mungo plants. A statistically significant increase in growth was observed in plants inoculated with isolates compared to uninoculated plants, both in presence and in absence of As. R. palustris CS2 treated plants showed 17% (28.1±0.87 cm) increase in shoot length and 21.7% (7.07±0.42 cm) increase in root length, whereas R. faecalis SS5 treated plants showed 12.8% (27.09±0.81 cm) increase in shoot length and 18.8% (6.9±0.34 cm) increase in root length as compared to the control plants. In presence of As, R. palustris CS2 increased shoot length up to 26.3% (21.0±1.1 cm), while root length increased up to 31.3% (5.3±0.4 cm), whereas R. faecalis SS5 inoculated plants showed 25% (20.7 ± 1.4 cm) increase in shoot length and 33.3% (5.4 ± 0.65 cm) increase in root length as compared to the control plants. Bacteria with such diverse abilities could be ideal for plant growth promotion in As-contaminated sites.

Abstract (sommario):
In this paper, a novel photosynthetic bacteria solar cell with Rhodopseudomonas as the electricity generation bacteria was designed and prepared, and photo current changing with the time of the cell was investigated by testing current-time(i-t) curve under alternating light and dark. The results showed that the maximum photo current of the cell could be 13 μA. The influence of glucose, sucrose, chitosan, anthraquinone and hydroquinone on the photo current was investigated. The results indicated that glucose and chitosan made the photo current of solar cell increased about 21 μA and 27 μA, respectively; but sucrose, anthraquinone or hydroquinone had not such effect. It illustrated that photo electrons could be emitted by Rhodopseudomonas and were transmitted to the anode of the cell in the presence of electronic media under light, and the photo current could be improved further by the adding of some additives.

Abstract (sommario):
To investigate the effect of microbial inoculum on soil heavy metal immobilisation, pot experiments were conducted with paddy soils contaminated by cadmium (Cd), lead (Pb), arsenic (As), and mercury (Hg), respectively. The results showed that the inoculation of Rhodopseudomonas palustris was more effective in the immobilisation of Pb and Cd in soils than the composite of R. palustris and Bacillus subtilis. Interestingly, a lower dosage of inoculum immobilised significantly more heavy metals than the higher dosage, potentially due to the competition of bacteria with limited nutrients. The heavy metal contents in rice grains also supported this finding, as less Pb and Cd were accumulated under the lower dosage. However, there were limited effects of microbial inoculations on the immobilisation of Hg and As. In general, our study indicated the effectiveness of R. palustris in immobilising Pb and Cd in soils and highlighted the importance of determining the optimal dosage of inoculum in bioremediation.
