A marine bacterium, designated strain KMM 6038T, was subjected to taxonomic analysis via a polyphasic approach. Cells of the strain were heterotrophic, orange-pigmented, Gram-negative and motile by means of gliding. 16S rRNA gene sequence analysis indicated that strain KMM 6038T was closely related to the type species of the genera Algibacter and Yeosuana, members of the family Flavobacteriaceae, with sequence similarities of 93.8 and 93.6 % to the respective type strains. However, several chemotaxonomic and phenotypic characteristics, such as the cellular fatty acid profile (iso-C15 : 0, anteiso-C15 : 0, iso-C15 : 1, C15 : 0, C15 : 1 ω6c, iso-C15 : 0 3-OH and iso-C17 : 0 3-OH) and the low G+C content of the DNA (35.7 mol%), indicated that the strain should be separated from these two genera. From the results of phenotypic, genotypic, chemotaxonomic and phylogenetic analyses, the bacterium should be classified as representing a novel genus and species, for which the name Mariniflexile gromovii gen. nov., sp. nov. is proposed. The type strain of Mariniflexile gromovii is KMM 6038T (=KCTC 12570T=LMG 22578T).

Sequence Similarities

A Gram-negative, non-motile bacterium, designated MJ17T, was isolated from sludge at the Daejeon sewage disposal plant in South Korea. Comparative 16S rRNA gene sequence analysis showed that strain MJ17T belonged to the genus Paracoccus in the family Rhodobacteraceae of the class Alphaproteobacteria. 16S rRNA gene sequence similarities between strain MJ17T and type strains of species of the genus Paracoccus were 94.1–97.4 %. The highest similarities were between strain MJ17T and Paracoccus homiensis DD-R11T, Paracoccus zeaxanthinifaciens ATCC 21588T and Paracoccus alcaliphilus JCM 7364T (97.4, 97.2 and 96.3 %, respectively). Strain MJ17T exhibited <22 % DNA–DNA relatedness with P. homiensis KACC 11518T and P. zeaxanthinifaciens JCM 21774T. The G+C content of the genomic DNA was 58.7 mol%. Strain MJ17T contained ubiquinone Q-10. The major fatty acids were C18 : 0 (11.3 %), C16 : 0 (10.2 %) and summed feature 7 (containing one or more of C18 : 1ω7c, C18 : 1ω9c and C18 : 1ω12t; 54.3 %). Poly-β-hydroxybutyrate granules are formed. On the basis of phenotypic and genotypic properties and phylogenetic distinctiveness, strain MJ17T should be classified in a novel species of the genus Paracoccus, for which the name Paracoccus caeni sp. nov. is proposed. The type strain is MJ17T ( = KCTC 22480T  = JCM 16385T  = KEMB 9004-001T).

Four thermophilic, Gram-positive strains, designated H0165T, 500275T, C0170 and 700375, were isolated from a composting process in Japan. The isolates grew aerobically at about 65 °C on a solid medium with formation of substrate mycelia; spores were produced singly along the mycelia. These morphological characters resembled those of some type strains of species belonging to the family ‘Thermoactinomycetaceae’, except that aerial mycelia were not formed. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the closest related species to the isolates were members of the family ‘Thermoactinomycetaceae’, but that the isolates formed an independent phylogenetic lineage. Some chemotaxonomic characters of the isolates, such as DNA G+C contents of 58·7–60·3 mol%, MK-7 as the major menaquinone and cellular fatty acid profiles, differed from those of members of the family ‘Thermoactinomycetaceae’. DNA–DNA hybridization showed that the isolates could be divided into two genomic groups, strain H0165T and the other three strains. These results indicated that the four isolates should be classified into two species of a novel genus in the family ‘Thermoactinomycetaceae’, for which the names Planifilum fimeticola gen. nov., sp. nov. (type strain H0165T=ATCC BAA-969T=JCM 12507T) and Planifilum fulgidum sp. nov. (type strain 500275T=ATCC BAA-970T=JCM 12508T) are proposed.

A novel actinobacterial strain was isolated from a seawater sample collected on Mara Island, Jeju, Republic of Korea. Cells of this organism were aerobic, Gram-positive, non-spore-forming, non-motile cocci that occurred singly or in pairs. Colonies were circular, smooth, convex and white–cream in colour. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family Dermacoccaceae and formed a monophyletic clade between the type strains of Demetria terragena (96.8 % similarity) and Branchiibius hedensis (95.2 % similarity). The cell-wall peptidoglycan contained l-lysine, alanine, aspartic acid, glutamic acid, glycine and serine, indicating that the isolate possessed peptidoglycan type A4α. The whole-cell sugars were galactose, glucose, mannose, xylose, arabinose, ribose and rhamnose. The major menaquinone was MK-8(H4). The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, an unknown phospholipid and five unknown lipids. The cellular fatty acid profile was represented by large amounts of iso-methyl branched and monounsaturated iso- and anteiso-methyl branched acids, along with the presence of a diagnostic 10-methyl acid. The G+C content of the DNA was 71 mol%. On the basis of data from polyphasic analyses presented here, strain MSW-24T is considered to represent a novel species of a new genus in the family Dermacoccaceae , for which the name Tamlicoccus marinus gen. nov., sp. nov. is proposed. The type strain of Tamlicoccus marinus is MSW-24T ( = KCTC 19485T = DSM 21415T).
