An obligately anaerobic bacterium, designated strain GK12T, was isolated from an anaerobic digester in Fukagawa, Hokkaido Prefecture, Japan. The cells of strain GK12T were non-motile, non-spore-forming cocci that commonly occurred in chains. 16S rRNA gene sequence analysis revealed that strain GK12T was affiliated with the family Erysipelotrichaceae in the phylum Firmicutes and showed 91.8 % sequence similarity to the most closely related species, Faecalicoccus acidiformans . The strain grew at 30–50 °C (optimally at 40 °C) and at pH 5.5–8.5 (optimally at pH 7.5). The main end product of glucose fermentation was lactate. Yeast extract was required for growth. The strain contained C14 : 0, C14 : 0 1,1-dimethoxyalkane (DMA), C16 : 0 DMA and C18 : 0 DMA as the major cellular fatty acids (>10 % of the total). The polar lipid profile was composed of phosphatidylglycerol, phosphatidylinositol and an unidentified phospholipid. The whole-cell sugars were galactose, rhamnose and ribose. The cell-wall murein contained alanine, glutamic acid, lysine, serine and threonine, but not diaminopimelic acid. The G+C content of the genomic DNA was 47.7 mol%. Based on phenotypic, phylogenetic and chemotaxonomic properties, a novel genus and species, Catenisphaera adipataccumulans gen. nov., sp. nov., is proposed to accommodate strain GK12T ( = NBRC 108915T = DSM 25799T).

A Gram-stain-negative, non-motile, mesophilic, aerobic, rod-shaped bacterium, designated strain 2-3T, was isolated from surface seawater at Muroto city, Kochi prefecture, Japan. This strain grew well with starch. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain fell within the family Rhodobacteraceae and that the strain was related most closely to the genus Pacificibacter (94.0 % sequence similarity to the type strain). The DNA G+C content was 52.4 mol%. The major fatty acids were C18 : 1ω7c, C14 : 0 and C16 : 0. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, one unidentified lipid, one unidentified aminolipid and one unidentified phospholipid. The major isoprenoid quinone was Q-10. Strain 2-3T did not grow at 4 or 35 °C, while the type strain of the type species of the genus Pacificibacter grows at both temperatures. From the taxonomic data obtained in this study, it is proposed that strain 2-3T be placed into a novel genus and species named Amylibacter marinus gen. nov., sp. nov. in the family Rhodobacteraceae . The type strain of Amylibacter marinus is 2-3T ( = NBRC 110140T = LMG 28364T).

A Gram-stain positive strain, M1T, was isolated from the sediment of Maar Lake in Zhanjiang, Guangdong Province, China. The diagnostic cell-wall diamino acid was meso-diaminopimelic acid, and mycolic acids were not detected. The polar lipid profile of strain M1T consisted of diphosphatidylglycerol, phosphatidylglycerol, an unidentified phospholipid and an unknown glycolipid. The predominant quinone was MK-7, with MK-6 as a minor component. The major fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0, with iso-C18 : 0 as a minor component. The DNA G+C content of the genomic DNA was 71.0 mol%. 16S rRNA gene sequence analysis showed that strain M1T belongs to the family Dermabacteraceae , sharing highest sequence similarity with Brachybacterium nesterenkovii JCM 11648T (98.1 %). Furthermore, a combination of DNA–DNA relatedness and physiological and biochemical properties indicated that the novel strain could be readily distinguished from its closest phylogenetic relatives. On the basis of these phenotypic and genotypic data, strain M1T represents a novel species of the genus Brachybacterium , for which the name Brachybacterium huguangmaarense sp. nov. is proposed. The type strain is M1T ( = CCTCC AB 2012866T = DSM 26370T).

A Gram-stain-positive bacterium, strain RV15T, forming an extensively branched substrate mycelium and aerial hyphae that differentiate into spiral chains of spores, was isolated from a marine sponge Dysidea tupha collected from Rovinj (Croatia). Comparison of 16S rRNA gene sequences showed that strain RV15T is a member of the genus Streptomyces with highest sequence similarity to the type strains of Streptomyces caeruleatus (98.8 %), Streptomyces cyaneochromogenes (98.6 %) and Streptomyces shaanxiensis (98.5 %). Sequence similarities to all other Streptomyces types strains were below 98.5 %. The multilocus sequence analysis-based evolutionary distance, the average nucleotide identity value and the genome-to-genome distance of strain RV15T and the type strain of S. caeruleatus were clearly below the species cut-off values. Strain RV15T exhibited a quinone system composed of the major menaquinones MK-9(H4), MK-9(H6) and MK-9(H2), typical for the genus Streptomyces . The polar lipid profile of strain RV15T consisted of the predominant compounds diphosphatidylglycerol and phosphatidylethanolamine, moderate amounts of phosphatidylinositol, phosphatidylinositol mannoside, an unidentified lipid and an unidentified phospholipid. Major polyamines were spermine and spermidine. The diagnostic diaminoacid of the peptidoglycan was meso-diaminopimelic acid. The major fatty acids were iso C16 : 0, anteiso C17 : 1 ω9c and anteiso C17 : 0. The results of physiological and biochemical tests allowed further phenotypic differentiation of strain RV15T from its most-related species and hence clearly merits species status. We propose the name Streptomyces dysideae sp. nov. with the type strain RV15T (=DSM 42110T=LMG 27702T).

Three Gram-stain-negative, non-motile, oxidase- and catalase-positive, rod-shaped, black, facultative phototrophic bacterial strains, RG-N-1aT, DMA-N-7a and RA-N-9 were isolated from the water sample from Lake Fertő/Neusiedler See (Hungary). Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the strains form a distinct linage within the family Rhodobacteraceae and their closest relatives are Tabrizicola piscis K13M18T (96.32%) followed by Cypionkella psychrotolerans PAMC 27389T (96.25%). The novel bacterial strains prefer alkaline environments and grow optimally at 23–33 °C in the presence of NaCl (1–2 w/v%). Bacteriochlorophyll a was detected. Cells contained exclusively ubiquinone Q-10. The major cellular fatty acids were C18 : 1ω7c, C19 : 1iso ω5c, C18 : 0 3-OH and C18 : 1ω7c 11-methyl. The polar lipid profile contains diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified phospholipid and four unidentified lipids. The assembled draft genome of RG-N-1aT had 33 contigs with N50 values 315 027 nt, 96× genome coverage, total length of 4 326 551 bp and a DNA G+C content of 64.9%. Genome-based calculations (genome-to-genome distance and DNA G+C percentage) and pairwise amino acid identity (AAI <73.5%) indicate that RG-N-1aT represents a novel genus. RG-N-1aT (=DSM 108317T=NCAIM B.02647T) is suggested as the type strain of a novel genus and species in the family Rhodobacteraceae , for which the name Fertoeibacter niger gen. nov., sp. nov. is proposed.
