Saporetti, Fabio. « Il ruolo delle zone umide della Regione Lombardia durante la migrazione dei limicoli : un’analisi per il genere Tringa ricavata dal portale www.ornitho.it ». Rivista Italiana di Ornitologia 87, no 2 (21 juin 2018) : 15–28. http://dx.doi.org/10.4081/rio.2017.369.

Résumé :
In Italy, the launch of the online portal at www.ornitho.it in 2009 has played a key role in advancing our knowledge about the abundance, geographical distribution and phenology of birds, and has greatly improved everyday ornithological issues. Indeed, the extensive participation by many observers has provided an opportunity to obtain new insight into the phenology of many species of migratory birds, such as Tringa sp. In this paper, I have analysed the data gathered between 2010 and 2014 on the genus Tringa in Lombardy, amounting to a total of 5,590 validated records for spring and autumn migrations. The analysis revealed that the rice-farming area of S-W Lombardy – which covers more than 90,000 hectares located mainly in the province of Pavia – represents an invaluable habitat during the spring migration by supporting the bulk of migrating waders. Other man-made habitats, such as restored sand and gravel pits and water-collection tanks, are of similar importance for the diversity of the wader community, but, together with the few natural wetlands, support much lower numbers of individuals. The wood sandpiper is the most abundant species, with groups reaching 600 individuals, followed by the spotted redshank and the greenshank. The green sandpiper is the most common and widespread species, with a low number of individuals reaching the highest altitudes (above 2,600 m a.s.l. in the province of Sondrio) during the autumn migration. The common redshank is relatively rare, generally distributed around 200 m a.s.l. in the provinces of Pavia and Milan, while the marsh sandpiper is definitely rare, with only 68 records in the five-year period analysed.

Résumé :
The diversity of filamentous bacteria present in industrial wastewater treatment plants was analysed by a combination of classical and molecular-biological approaches. Many unknown filamentous bacteria were observed in about 80 screened activated sludge samples from different industries with sometimes severe bulking sludge problems. A special focus was paid to filaments which resembled “Nostocoida limicola”, a filamentous bacterium which was found to be present in many WWTPs. These filamentous bacteria are hardly cultivable and only one strain was obtained and maintained in co-culture with a yeast. The 16S rRNA sequences of several other “Nostocoida limicola”-like filamentous bacteria from different sludge samples were obtained by micromanipulation and different molecular-biological methods. The sequences were phylogenetically analyzed and specific molecular probes were developed and applied. The results clearly demonstrate that “Nostocoida limicola”-like filaments from industrial WWTPs are different from all other “Nostocoida limicola” types investigated so far. Our strains are affiliated to the alpha-subclass of Proteobacteria.

Résumé :
The water mite Rutripalpus limicola Sokolow, 1934, can be considered exceptionally rare. It shows a scattered distribution range and, until recently, was known from six sites across Europe only. This strictly spring-dwelling species has a highly localised distribution, presumably due to its specific ecological requirements. We present the first records of R. limicola in the Netherlands and review the current state of knowledge on its distribution and biology. In addition to the previously existing morphology-based investigations, we provide a phylogenetic placement based on 28S rRNA gene data and shed light on the controversial systematic position of R. limicola: In contrast to the previously hypothesised Lebertioidea-relatedness of the isolated, monotypic family Rutripalpidae, our results reveal a putative Hydryphantoidea association. Moreover, we discuss the host-parasite association of R. limicola larvae and the dipteran family Ptychopteridae. Combined with additional information derived from the new records from the Netherlands, we contribute to a better understanding of this elusive species' biology and phylogenetic position.

Résumé :
On the basis of 16S rRNA sequence analyses of several isolates of “Nostocoida limicola” from activated sludge plants in Australia and other countries, it is clear that “N. limicola” I, II and III are not three morphological variants of a single bacterium but at least three phylogenetically different bacteria. Data show that “N. limicola” I are members of at least two genera in the low mol% G+C Gram-positive bacteria, while some isolates of “N.limicola” II belong to the high mol% G+C Gram positive bacteria, and “N.limicola” III is a member of the Planctomycetales. Design and application of 16S rRNA targeted probes for each to biomass samples suggests that their phylogeny is more diverse than pure culture studies would suggest.

Résumé :
The in situ physiology of the actinobacterial bulking and foaming filamentous bacterium “Nostocoida limicola” II was studied by fluorescence in situ hybridization/microautoradiography. Substrate assimilation patterns of pure cultures of this bacterium were different to those seen in activated sludge biomass samples. There was no evidence to suggest that “N. limicola” II preferred hydrophobic substrates, but evidence was produced to support the view that it is metabolically active under anaerobic conditions in activated sludge.

Résumé :
Despite differences in their morphologies, comparative analyses of 16S rRNA gene sequences revealed high levels of similarity (>94 %) between strains of the filamentous bacterium ‘Candidatus Nostocoida limicola’ and the cocci Tetrasphaera australiensis and Tetrasphaera japonica and the rod Tetrasphaera elongata, all isolated from activated sludge. These sequence data and their chemotaxonomic characters, including cell wall, menaquinone and lipid compositions and fingerprints of their 16S–23S rRNA intergenic regions, support the proposition that these isolates should be combined into a single genus containing six species, in the family Intrasporangiaceae in the Actinobacteria. This suggestion receives additional support from DNA–DNA hybridization data and when partial sequences of the rpoC1 gene are compared between these strains. Even though few phenotypic characterization data were obtained for these slowly growing isolates, it is proposed, on the basis of the extensive chemotaxonomic and molecular evidence presented here, that ‘Candidatus N. limicola’ strains Ben 17, Ben 18, Ben 67, Ben 68 and Ben 74 all be placed into the species Tetrasphaera jenkinsii sp. nov. (type strain Ben 74T=DSM 17519T=NCIMB 14128T), ‘Candidatus N. limicola’ strain Ben 70 into Tetrasphaera vanveenii sp. nov. (type strain Ben 70T=DSM 17518T=NCIMB 14127T) and ‘Candidatus N. limicola’ strains Ver 1 and Ver 2 into Tetrasphaera veronensis sp. nov. (type strain Ver 1T=DSM 17520T=NCIMB 14129T).

Résumé :
Due to the high content of organic compounds, the distillery wastewater can be a good substrate for the production of glycogen during cultivation of green photosynthetic bacteria. Green photosynthetic bacteria Chlorobium limicola IMV K-8 are producers of glycogen and show exoelectrogenic properties when grown alone or inside the co-culture with heterotrophic bacteria-exoelectrogens in wastewater of various origins. In our previous works it was found that due to the phototrophic growth of C. limicola IMV K-8 in the distillery wastewater significantly reduces the content of compounds of nitrogen, sulfur, Ca2+, Mg2+ and others. The study of the patterns of glycogen synthesis by green photosynthetic bacteria during growth in such an extreme environment as the wastewater of a distillery has prospects for the development of biotechnology for the production of this polysaccharide. The aim of the study was to investigate the glycogen content in C. limicola IMV K-8 cells under different growth conditions in the wastewater of the distillery. Bacteria were grown in the wastewater of the distillery under light (phototrophic growth) and without light exposure (heterotrophic growth). Bacterial cells grown on GSB medium under light (phototrophic growth) and without light (heterotrophic growth) exposure were used as controls. Glycogen content was determined at 7, 14, 21 and 30 days of growth by the glucose oxidase method. Glucose or glycogen in the wastewater of the distillery without the introduction of bacteria was not detected. It was found that the content of glycogen in cells of C. limicola IMV K-8 grown in the wastewater of the distillery, under light exposure increased from 3.8 % to 39.8 % of cells dry weight from the seventh to third day of growth during 30 days of cultivation and was 2 times higher the glycogen content of cells on GSB medium. It is assumed that the bacteria C. limicola IMV K-8 use available in the water sources of carbon and other compounds necessary for cell metabolism along with glycogen biosynthesis and bioremediation of wastewater. During C. limicola IMV K-8 growth in the darkness there is an assimilation of organic sources of carbon (acetate, pyruvate and probably organic compounds of wastewater), which allows cells to remain viable for 30 days without additional sources of carbon, nitrogen, etc., but significant glycogen synthesis does not occur. The glycogen formed under phototrophic conditions can be further a source of carbon or a substrate for electric current generation by exoelectrogenic bacteria.

Résumé :
A halophilic archaeon named strain LR21T was isolated from a salt mine in Yunnan Province, PR China. Cells were spherical, Gram-stain-negative and motile. Strain LR21T grew at 20–50 °C (optimum, 42 °C), with 8–30 % (w/v) NaCl (optimum, 23 %) and at pH 5.5–9.5 (optimum, pH 7.5–8.5). Mg2+ was not required for growth. The major polar lipid profile comprised phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and phosphatidylglycerol sulfate. Strain LR21T had two dissimilar 16S rRNA genes (rrnA and rrnB) and they were closely related to Halomicroarcula limicola YGHS32T, Hma. pellucida BNERC31T and Hma. salina YGHS18T with sequence similarities of 95.3–99.0, 93.0–96.2 and 93.2–95.9 %, respectively, and much lower values to other members. The rpoB′ gene sequence similarities between strain LR21T and Hma. limicola YGHS32T, Hma. pellucida BNERC31T and Hma. salina YGHS18T were 95.2, 91.2 and 91.2 % respectively. The values of average nucleotide identity (ANI) and average amino-acid identity (AAI) between strain LR21T and Hma. limicola YGHS32T, were 89.0 and 90.1 %, respectively. DNA relatedness between strains LR21T and Hma. limicola YGHS32T determined by in silico DNA–DNA hybridization was 36.8 %. Values of ANI and AAI between strain LR21T and other members in the genus Halomicroarcula were far below 95 % and the DNA–DNA relatedness values between strain LR21T and its close relatives were much lower than 70 %, which is far below the boundary for delineation of a new species prokaryote. The DNA G+C content of strain LR21T was 62.0 mol% (genome). The results suggested that strain LR21T represents a novel species of the genus Halomicroarcula , for which the name Halomicroarcula amylolytica sp. nov. is proposed. The type strain is LR21T (=CGMCC 1.13611T=NBRC 113588T).

Two spionid polychaetes, Polydora cornuta and Streblospio gynobranchiata, were identified in benthic samples collected in the northern Black Sea and adjacent waters. These species have earlier been classified as the worst invaders in soft bottom communities in the Mediterranean Sea. Polydora cornuta had been previously misidentified and widely reported from the Black Sea and the Sea of Azov as P. ciliata, P. ciliata limicola and P. limicola. Streblospio gynobranchiata is a new invader currently extending its distribution into the Mediterranean, Black and Caspian Seas. Morphology, diagnostic characters and biology of the species are discussed and the history of their records in the Mediterranean, Black and Caspian Seas and the Sea of Azov is reviewed.

Résumé :
The subfamily Aphrodinae (Hemiptera: Cicadellidae) contains ~33 species in Europe within four genera. Species in two genera in particular, Aphrodes and Anoscopus, have proved to be difficult to distinguish morphologically. Our aim was to determine the status of the putative species Anoscopus duffieldi, found only on the RSPB Nature Reserve at Dungeness, Kent, a possible rare UK endemic. DNA from samples of all seven UK Anoscopus species (plus Anoscopusalpinus from the Czech Republic) were sequenced using parts of the mitochondrial cytochrome oxidase I and 16S rRNA genes. Bayesian inference phylogenies were created. Specimens of each species clustered into monophyletic groups, except for Anoscopusalbifrons, A. duffieldi and Anoscopuslimicola. Two A. albifrons specimens grouped with A. duffieldi repeatedly with strong support, and the remaining A. albifrons clustered within A. limicola. Genetic distances suggest that A. albifrons and A. limicola are a single interbreeding population (0% divergence), while A. albifrons and A. duffieldi diverged by only 0.28%. Shared haplotypes between A. albifrons, A. limicola and A. duffieldi strongly suggest interbreeding, although misidentification may also explain these topologies. However, all A. duffieldi clustered together in the trees. A conservative approach might be to treat A. duffieldi, until other evidence is forthcoming, as a possible endemic subspecies.

Résumé :
The extent of activated sludge separation problems associated with excessive growth of filamentous microorganisms has increased recently in the Czech Republic. Most of the activated sludge plants in the country were contacted by mail with a questionnaire, the aim of which was to obtain the basic technological data on the plants and on the nature and intensity of activated sludge separation problems. Selected activated sludge plants were visited at different periods of the year and samples of activated sludge mixed liquor and foam were collected for microscopic examination and kinetic batch tests. It was found that good settling properties were associated more with good quality activated sludge flocs than with the absence of filaments. On the other hand, a very high abundance of filaments always resulted in bulking or foaming. The most common filamentous microorganisms in activated sludge mixed liquors were M. parvicella, N. limicola and Types 0092, 0041 and 0803 while the foams were mostly dominated by M. parvicella, NALOs (GALOs) and N. limicola. Seasonal shifts in filamentous population diversity were also observed. M. parvicella, Type 0092, N. limicola, Type 0803 and Type 0041 were dominant in both conventional and biological nutrient removal activated sludge plants whereas the other Eikelboom's types of filaments dominated mostly in conventional activated sludge plants. The ability of foams to denitrify depended on the dominating filamentous microorganism and type of substrate.

Résumé :
The genus Desulfonema belongs to the deltaproteobacterial family Desulfobacteraceae and comprises marine, sulfate-reducing bacteria that form filaments and move by gliding. This study reports on the complete, manually annotated genomes of Dn. limicola 5ac10T (6.91 Mbp; 6,207 CDS) and Dn. magnum 4be13T (8.03 Mbp; 9,970 CDS), integrated with substrate-specific proteome profiles (8 vs. 11). The richness in mobile genetic elements is shared with other Desulfobacteraceae members, corroborating horizontal gene transfer as major driver in shaping the genomes of this family. The catabolic networks of Dn. limicola and Dn. magnum have the following general characteristics: 98 versus 145 genes assigned (having genomic shares of 1.7 vs. 2.2%), 92.5 versus 89.7% proteomic coverage, and scattered gene clusters for substrate degradation and energy metabolism. The Dn. magnum typifying capacity for aromatic compound degradation (e.g., p-cresol, 3-phenylpropionate) requires 48 genes organized in operon-like structures (87.7% proteomic coverage; no homologs in Dn. limicola). The protein complements for aliphatic compound degradation, central pathways, and energy metabolism are highly similar between both genomes and were identified to a large extent (69–96%). The differential protein profiles revealed a high degree of substrate-specificity for peripheral reaction sequences (forming central intermediates), agreeing with the high number of sensory/regulatory proteins predicted for both strains. By contrast, central pathways and modules of the energy metabolism were constitutively formed under the tested substrate conditions. In accord with their natural habitats that are subject to fluctuating changes of physicochemical parameters, both Desulfonema strains are well equipped to cope with various stress conditions. Next to superoxide dismutase and catalase also desulfoferredoxin and rubredoxin oxidoreductase are formed to counter exposure to molecular oxygen. A variety of proteases and chaperones were detected that function in maintaining cellular homeostasis upon heat or cold shock. Furthermore, glycine betaine/proline betaine transport systems can respond to hyperosmotic stress. Gliding movement probably relies on twitching motility via type-IV pili or adventurous motility. Taken together, this proteogenomic study demonstrates the adaptability of Dn. limicola and Dn. magnum to its dynamic habitats by means of flexible catabolism and extensive stress response capacities.

Résumé :
Two species of photosynthetic sulphur bacteria, Chlorobium phaeobacteroides and Chlorobium limicola, found growing under different environmental conditions in the Kinneret, were cultured in the laboratory under various orthophosphate (Pi) concentrations and light intensities. Growth was followed using direct ceil counts, protein content, and pigment content. In general, the same growth pattern was shown by all three parameters and the final cell yields of both species were dependent on ambient Pi concentrations. Chlorobium limicola compensated for low light intensities by increasing pigment production. In addition, light (but not apparently the Pi concentration) influenced the lag period of these cells, with a longer lag observed at lower light intensities. Intra- and extra-cellular activities of both acid and alkaline phosphatases were generally detected in both bacterial species. As Pi levels dropped, both the intra- and extra-cellular activities of acid and alkaline phosphatases increased, suggesting that both enzymes were inducible, although the interaction of P and light limitations was often complex. At high Pi concentrations, residual activities of both acid and alkaline phophatases were detected, probably reflecting the activity of constitutive enzymes not involved in P nutrition of the cells. Extracellular acid and alkaline phophatase activities were low and approximately constant at all light levels. Intracellular activities were relatively high and influenced by light, exhibiting saturation kinetics, and suggest that alkaline phosphatase is more sensitive to light than acid phosphatase. At low Pi concentrations, intracellular phosphatase activities were high and approximately constant over the range of light intensities examined, whereas activities of the extracellular enzymes were low but increased at lower light levels.Key words: photosynthetic bacteria, Chlorobium phaeobacteroides, Chlorobium limicola, growth, phosphate concentration, phosphatases.

Résumé :
Background The genus Calidris (Charadriiformes, Scolopacidae) includes shorebirds known as dunlin, knots, and sanderlings. The relationships between species nested within Calidris, including Eurynorynchus, Limicola and Aphriza, are not well-resolved. Methods Samples were collected from Xiaoyangkou, Rudong County, Jiangsu Province, China. Mitogenomes were sequenced using the Illumina Novaseq 6000 platform for PE 2 × 150 bp sequencing, and then checked for PCR products. Protein-coding genes were determined using an Open Reading Frame Finder. tRNAscan-SE, MITOS, and ARWEN were used to confirm tRNA and rRNA annotations. Bioinformatic analyses were conducted using DnaSP 5.1 and MEGA X. Phylogenic trees were constructed using maximum likelihood and Bayesian analyses. Results We sequenced and annotated the mitogenome of five species and obtained four complete mitogenomes and one nearly complete mitogenome. Circular mitogenomes displayed moderate size variation, with a mean length of 16,747 bp, ranging from 16,642 to 16,791 bp. The mitogenome encoded a control region and a typical set of 37 genes containing two rRNA genes, 13 protein-coding genes, and 22 tRNA genes. There were four start codons, four stop codons, and one incomplete stop codon (T–). The nucleotide composition was consistently AT-biased. The average uncorrected pairwise distances revealed heterogeneity in the evolutionary rate for each gene; the COIII had a slow evolutionary rate, whereas the ATP8 gene had a fast rate. dN/dS analysis indicated that the protein-coding genes were under purifying selection. The genetic distances between species showed that the greatest genetic distance was between Eurynorhynchus pygmeus and Limicola falcinellus (22.5%), and the shortest was between E. pygmeus and Calidris ruficollis (12.8%). Phylogenetic trees revealed that Calidris is not a monophyletic genus, as species from the genera Eurynorynchus and Limicola were nested within Calidris. The molecular data obtained in this study are valuable for research on the taxonomy, population genetics, and evolution of birds in the genus Calidris.

Résumé :
Ten strains of “Nostocoida limicola”-like organisms were isolated from a municipal wastewater treatment plant with minor industrial effluent. The near complete 16S rDNA sequences were determined for four strains to analyze the position of the organisms within the phylogenetic tree. All four isolates showed the same 16S rRNA sequence and cluster within the green non sulfur bacteria. Hybridization with oligonucleotide probe AHW183 designed complementarily to diagnostic regions of the 16S rRNA sequences showed a positive reaction with all isolated strains. Hybridization of activated sludge samples with probe AHW183 indicates the filamentous “Nostocoida limicola”-like bacteria commonly to occur inside the sludge flocs and to hardly be detected within the flocs without a specific staining. On HA-medium all strains grow as long coiled, unbranched and unsheathed filaments which usually stain Gram positive and show a variable Neisser reaction. The isolates grow well in liquid HA-medium at COD values between 1 to 4 g O2 l−1 and a pH range from 6.0–7.8. No growth is detected in liquid R2A-medium and several synthetic mineral salts media containing various carbon and nitrogen sources.

Résumé :
Three rod-shaped halophilic archaeal strains, DL-M4T, LYG-109 and DLLS-108T, were isolated from the salted brown alga Laminaria produced in different marine areas of PR China. Cells of strains were motile, formed red-pigmented colonies on agar and lysed in distilled water. The three strains grew optimally with 2.6 M NaCl, with 0.05–0.3 M MgCl2, at 37 °C and at pH 7.0–7.5. The results of phylogenetic analyses based on the 16S rRNA and rpoB′ genes differentiated these strains into two clusters belonging to the genus Halostella , which currently contains Halostella salina CBA1114T and Halostella limicola LT12T. Strains DL-M4T and LYG-109 formed a single cluster separate from the current two members of Halostella (94.4–95.7 and 90.0–90.9 % similarities, respectively) while strain DLLS-108T had Hsl. salina CBA1114T as its nearest neighbour (97.7–97.8 and 95.9 % similarities, respectively) and was separated from Hsl. limicola LT12T (94.4–95.8 and 93.4 % similarities, respectively). These clusters represented two distinct novel species as indicated by phenotypic characteristics, polar lipid compositions and whole-genome comparisons. Diverse phenotypic characteristics, morphology and growth characteristics, nutrition and miscellaneous biochemical tests differentiate strains DL-M4T, LYG-109, DLLS-108T from Hsl. limicola LT12T and Hsl. salina CBA1114T. Strains DL-M4T and LYG-109 contained phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and three unidentified glycolipids, while strain DLLS-108T contained these polar lipids and two unidentified phospholipids. The major respiratory quinones detected in the three isolates were menaquinone MK-8 and MK-8(H2). The average nucleotide identity (ANI) and in silico DNA–DNA hybridization (isDDH) values between the isolated strains and the current two members of Halostella were found to be 79.3–86.6 (ANI) and 22.9–49.8 % (isDDH). All these results showed that the three isolates represent two novel species of the genus Halostella for which the names Halostella pelagica sp. nov. [type strain dl-M4T (=CGMCC 1.13603T=JCM 32954T)] and Halostella litorea sp. nov. [type strain DLLS-108T(=CGMCC 1.13610T=JCM 32955T)] are proposed.

Résumé :
An activated sludge was cultivated on a mixture of several soluble substrates (acetate, ethanol, glucose, glutamic acid, peptone, Tween 80, starch, yeast extract) in an anoxic/aerobic SBR. Highly dynamic conditions in the SBR (feast famine regime) caused fast removal of most COD in the anoxic phase (in particular acetate, ethanol, glutamic acid and glucose were totally removed) and relevant contribution of storage. In spite of that, filament abundance was always high, as is typical of bulking sludges. Filaments which developed in the reactor were characterized on a morphological basis and on the basis of their ability to grow and to store polyhydroxyalkanoates (PHAs). Three main filaments prevailed in the biocenosis, whose relative abundance was varyng with time: Nostocoida limicola II, (two different morphological types), Haliscomenobacter hydrossis and an unidentified one. It was found that maximum growth rate was higher for flocformers than for filaments on each of the tested substrates. Epifluorescence showed that storage ability was more widespread among flocformers than in the filaments. Only one type of Nostocoida limicola II was able to store PHAs. The obtained data show that aerobic growth on the little residual fraction of COD from the anoxic phase was enough to support high abundance of filamentous microorganisms.

Résumé :
Two common sigalionid species from the Northeast Atlantic, Sthenelais boa (Johnston, 1833) and S. limicola (Ehlers, 1864), have never been revised in detail. Although their validity has never been questioned, a number of taxonomic problems related to Sthenelais Kinberg, 1856 and the later established Fimbriosthenelais Pettibone, 1971 remain unresolved. The validity of F. minor (Pruvot & Racovitza, 1895) has been repeatedly discussed, but no agreement reached. Also the validity of Fimbriosthenelais has been at stake, affecting the generic assignment of Fimbriosthenelais zetlandica (McIntosh, 1876), another species present in the area. Among the investigated species of Sthenelais, some where thought to be synonyms of Eusthenelais hibernica McIntosh, 1876, which led us to also include Eusthenelais McIntosh, 1876. We also re-examined Eusthenelais abyssicola McIntosh, 1879, the only other species attributed to the genus, and confirm that it is indeterminable. In total, we investigated 37 nominal taxa reported from the Northeast Atlantic and as a result we consider only five species to be valid: Sthenelais boa, S. limicola, Fimbriosthenelais zetlandica, F. longipinnis (Grube, 1869) and Eusthenelais hibernica. These genera and species are described and discussed herein and an updated identification key to all Northeast Atlantic species of Sigalioninae Gonzalez et al., 2018 is given.

Résumé :
An investigation comprising four studies was undertaken to determine possible factors affecting the growth of several different types of filamentous microorganisms present in a bulking industrial wastewater activated sludge. Results from laboratory-scale continuous-flow and full-scale studies suggested that DO concentration and F:M ratio were the likely key factors affecting filamentous growth in the activated sludge. From the results of two laboratory studies isolating the effects of DO concentration and F:M ratio on filamentous growth, favorable growth ranges of DO concentration or F:M ratio were estimated for the following filaments: Microthrix parvicella, Nocardia spp., Nostocoida limicola II, and Types 0041, 1851, and 1863. Most of the bacteria causing filamentous bulking of the activated sludge were found to be filaments typically associated with low F:M, and increasing the F:M ratio appeared to cause N. limicola II to lose its competitive advantage in the activated sludge system. Type 1863, on the other hand, was found to be a low DO filament, as DO concentrations of 0.1 mg O2/l or less appeared to be a necessary condition for its filamentous growth. Though Nocardia was found to be a low F:M filament, its growth also seemed to be affected by DO concentration, as its growth was stimulated by concentrations of 1.0 mg O2/l or greater, with a near linear relationship up to at least 5 mg O2/l.

Résumé :
Summay Based on the structure of limipterin (Cha, Pfleiderer, and Yim, Helv, Chim. Acta, 78: 600-614. 1995 the biosynthetic pathway for the newly identified pterin glycoside was investigated. It was demonstrated that tetrahydrolimipterin (H4 -limipterin) can be synthesized from GTP by the enzymes GTP cyclohydrolase I, 6-pyruvoyltetrahydropterin (PTP) synthase, sepiaptcrin reductase and limipterin synthase, present in the extract of Chlorobium limicola. Limipterin synthase (UDP-N -acetylglucosamine:5 ,6,7 ,8-tetrahydro-L-biopterin 2'-O-β-N-acetylglucosaminyl transferase) catalyzed the condensation of tetrahydrobiopterin (H4-biopterin) with UDP-N-acetylglucosamine in the presence of dithiothreitol and MnCl2. It could also produce D-tepidopterin, [1-O-(D-threo- biopterin-2'-yl)- β-N -acetylglucosamine] when 5,6,7 ,8-tetrahydro-D-threobiopterin and UDP-N-acetylglucosamine were used as substrates . Substrate analogues such as UTP, UDP and UDP-Nacetylgalactosamine inhibit the enzyme activity. The Km values for tetrahydrobiopterin and UDP-N-acetylglucosamine were 42.2 μM and 124.3 μM, respectively. Optimum pH and temperature were pH 8.0 and 37°C. The molecular weight of the enzyme was calculated to be 46,300 dalton from a calibrated Superdex 75 and the subunit molecular weight was estimated at 46,000 dalton by SDS-PAGE. These results suggest that limipterin synthase exists as a monomer. Biosynthetic intermediates of H4-limipterin such as N2NTP , 6-PTP, and H4-biopterin were identified in vitro using purified GTP cyclohydrolase I, PTP synthase, sepiapterin reductase, and limipterin synthase. From the HPLC and TLC analyses of the enzymic intermediater, it could be concluded that H4-limipterin comes from GTP by way of H4-biopterin in Chlorobium limicola.

Résumé :
A marine actinomycete strain, designated KSW2-15T, was isolated from a dried seaweed sample collected from a sandy beach on the coast of Jeju in the Republic of Korea. The organism produced non-motile, non-endospore-forming, Gram-positive, coccoid cells. The colonies were circular, translucent and yellow in colour with entire margins. meso-Diaminopimelic acid was present as the diamino acid of the peptidoglycan. The acyl type of the muramic acid was acetyl. Mycolic acids were not present. The predominant menaquinone was MK-8(H4). The polar lipids were phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were of the saturated, unsaturated and iso-branched methyl types. The DNA G+C content was 74 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain KSW2-15T formed a loose association with ‘Candidatus Nostocoida limicola’, within the radiation of the family Intrasporangiaceae of the suborder Micrococcineae. The organism showed the highest levels of sequence similarity with ‘Candidatus Nostocoida limicola’ (96.1 %), Terrabacter tumescens (96.1 %) and Terrabacter terrae (96.0 %). The levels of 16S rRNA gene sequence similarity between the isolate and members of other genera of the family Intrasporangiaceae were in the range 92.1–95.5 %. On the basis of the polyphasic evidence, the isolate should be classified within a novel genus and species, for which the name Phycicoccus jejuensis gen. nov., sp. nov. is proposed. The type strain of Phycicoccus jejuensis is strain KSW2-15T (=KCCM 42315T=NRRL B-24460T).

The excessive growth of filamentous bacteria and the resultant bulking of activated sludge constitute a serious problem in numerous wastewater treatment plants. Lecane inermis rotifers were previously shown to be capable of reducing the abundance of Microthrix parvicella and Nostocoida limicola in activated sludge. In the present study, the effectiveness of four Lecane clones in reducing the abundance of Type 021N filamentous bacteria was investigated. Three independent experiments were carried out on activated sludge from three different treatment plants. We found that Lecane rotifers are efficient consumers of Type 021N filaments.
