A Gram-staining-negative, non-motile, yellow-coloured, rod-shaped bacterium, designated S44T, was isolated from bankside soil of Xixi wetland, located in Zhejiang province, China. Growth of strain S44T was observed at 6–37 °C (optimum, 28 °C) and at pH 6.0–9.0 (optimum, 7.0). No growth occurred in the presence of >2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain S44T represented a member of the genus Flavobacterium , showing the highest sequence similarities to the sequences from Flavobacterium succinicans DSM 4002T (96.9 %), Flavobacterium reichenbachii WB 3.2-61T (96.6 %) and Flavobacterium glycines NCBI 105008T (96.5 %). The G+C content of the genomic DNA was 33.6 mol%. The predominant cellular fatty acids were C15 : 0, iso-C15 : 0, anteiso-C15 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), and the major respiratory quinone was menaquinone 6 (MK-6). The major polar lipids were phosphatidylethanolamine, two unknown aminolipids, two unknown aminophospholipids and four unknown polar lipids. On the basis of the phenotypic and genotypic data, it is proposed that the isolate S44T be classified as representing a novel species of the genus Flavobacterium , for which the name Flavobacterium palustre sp. nov. is proposed. The type strain is S44T ( = CGMCC 1.12811T = NBRC 110389T).

A strictly anaerobic, mesophilic, iron-reducing bacterial strain, IRF19T, was isolated from coal-contaminated soil in the Republic of Korea. IRF19T cells were straight, rod-shaped, Gram-staining-negative and motile by means of flagella. The optimum pH and temperature for their growth were determined to be pH 7.5–8.0 and 40 °C, while the optimum range was pH 6.5–10.0 and 20–45 °C, respectively. Strain IRF19T did not require NaCl for growth but it tolerated up to 2 % (w/v). Growth was observed with yeast extract, d-glucose, d-fructose, d-ribose, d-mannitol, d-mannose, l-serine, l-alanine and l-isoleucine. Fe(III), elemental sulfur, thiosulfate and sulfate were used as electron acceptors. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain IRF19T is affiliated to the family Clostridiaceae and is most closely related to Salimesophilobacter vulgaris Zn2T (93.5 % similarity), Geosporobacter subterraneus VNs68T (93.2 %) and Thermotalea metallivorans B2-1T (92.3 %). The major cellular fatty acids of strain IRF19T were C14 : 0, iso-C15 : 0 and C16 : 0, and the profile was distinct from those of the closely related species. The major respiratory quinone of strain IRF19T was menaquinone MK-5 (V-H2). The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unknown phospholipid and two unknown polar lipids. The G+C content of the genomic DNA of strain IRF19T was determined to be 37.4 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic results, strain IRF19T is considered to represent a novel species of a novel genus of the family Clostridiaceae , for which we propose the name Anaerosolibacter carboniphilus gen. nov., sp. nov., with the type strain IRF19T ( = KCTC 15396T = JCM 19988T).
