Abstract

Two novel bacteria, strains TR7-09 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 : 09 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 DSM 13605, KCTC 12236 and LMG 568 (with 92.5, 92.0 and 92.0 % sequence similarity, respectively) and formed a separate lineage within the family The combined genotypic and phenotypic data supported the conclusion that the strains represent a novel genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain is TR7-09 (=KCTC 12666=DSM 18010).
