Two novel bacteria, strains TR7-09T and P2-12-1, were isolated from samples of compost and river sediment, respectively. The strains comprised Gram-negative, motile, non-spore-forming rods, produced creamy white colonies on R2A agar, contained Q-8 as the predominant ubiquinone, contained iso-15 : 0, iso-17 : 0ω9c and iso-11 : 0 3-OH as the major fatty acids, and had polar lipid profiles consisting of phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol and an unknown phospholipid. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strains were most closely related to Thermomonas haemolytica DSM 13605T, Silanimonas lenta KCTC 12236T and Xanthomonas campestris LMG 568T (with 92.5, 92.0 and 92.0 % sequence similarity, respectively) and formed a separate lineage within the family Xanthomonadaceae. The combined genotypic and phenotypic data supported the conclusion that the strains represent a novel genus and species, for which the name Aspromonas composti gen. nov., sp. nov. is proposed. The type strain is TR7-09T (=KCTC 12666T=DSM 18010T).

Two actinomycete strains, TT2-10T and TT2-3, which produced long spore chains (more than 10 spores per chain), were isolated from peat swamp forest soil in Pattaloong Province, Thailand. Their taxonomic positions were determined using a polyphasic approach. The chemotaxonomic characteristics of these strains coincided with those of the family Micromonosporaceae, i.e. cell-wall chemotype II, muramic acid of the N-glycolyl type, whole-cell sugar pattern D and type II phospholipids. Analysis of the 16S rRNA gene sequences also indicated that these strains constitute a distinct lineage within the family Micromonosporaceae, sharing 91.3–93.8 % sequence similarity with members of this family. On the basis of their phenotypic and genotypic characteristics and their phylogenetic position, these strains represent a novel genus and species, for which the name Actinocatenispora thailandica gen. nov., sp. nov. is proposed. The type strain of Actinocatenispora thailandica is strain TT2-10T (=JCM 12343T=PCU 235T=DSM 44816T).

A Gram-staining-negative, pink bacterium, designated strain BUZ 2T, was isolated from coastal mud from the North Sea (Fedderwardersiel, Germany). Cells were rod-shaped and able to form multicellular filaments. Growth after 7 days was observed at 10–40 °C, at pH 6–8 and with 0–0.5 % NaCl. The phylogenetic tree based on 16S rRNA gene sequences indicated that strain BUZ 2T is a member of the family Cytophagaceae, its closest neighbours being Rudanella lutea 5715S-11T, Spirosoma linguale LMG 10896T and Spirosoma panaciterrae Gsoil 1519T (87.8, 86.4 and 86.1 % sequence similarity, respectively). The major fatty acids were summed feature 3 (comprising C16 : 1 ω7c and/or iso-C15 : 0 2-OH), C16 : 1 ω5c and iso-C15 : 0. The predominant respiratory quinone was MK-7 and the major polar lipids were phosphatidylethanolamine and several unidentified aminophospholipids. The DNA G+C content was 56.5 mol%. On the basis of this polyphasic study, we propose that strain BUZ 2T represents a novel genus and species, for which the name Fibrella aestuarina gen. nov., sp. nov. is proposed. The type strain of Fibrella aestuarina is BUZ 2T (=DSM 22563T =CCUG 58136T). An emended description of the genus Rudanella is also proposed.

© 2017 IUMS. A novel anaerobic pectinolytic bacterium (strain 14T) was isolated from human faeces. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 14T belonged to the family Ruminococcaceae, but was located separately from known clostridial clusters within the taxon. The closest cultured relative of strain 14T was Acetivibrio cellulolyticus (89.7% sequence similarity). Strain 14T shared ~99% sequence similarity with cloned 16S rRNA gene sequences from uncultured bacteria derived from the human gut. Cells were Gram-stain-positive, non-motile cocci approximately 0.6μm in diameter. Strain 14T fermented pectins from citrus peel, apple, and kiwifruit as well as carbohydrates that are constituents of pectins and hemicellulose, such as galacturonic acid, xylose, and arabinose. TEM images of strain 14T, cultured in association with plant tissues, suggested extracellular fibrolytic activity associated with the bacterial cells, forming zones of degradation in the pectin-rich regions of middle lamella. Phylogenetic and phenotypic analysis supported the differentiation of strain 14T as a novel genus in the family Ruminococcaceae. The name Monoglobus pectinilyticus gen. nov., sp. nov. is proposed; the type strain is 14T (JCM 31914T=DSM 104782T).
