Abstract

A novel bacterial strain, designated M2T2B15, was isolated from fermented bovine products and was characterized by using a polyphasic approach. Colonies were reddish pink and circular with entire margins. Cells were strictly aerobic, Gram-reaction-negative, oxidase- and catalase-positive rods that lacked flagella and were motile by gliding. Flexirubin-type pigments were absent. 16S rRNA gene sequence analysis indicated that strain M2T2B15 was related most closely to LMG 22510 (94.4 % similarity) but shared <87 % similarity with other members of the phylum . The major cellular fatty acids were C 5, iso-C and iso-C 3-OH. The polar lipids were phosphatidylethanolamine, phosphatidylserine, two unidentified aminophospholipids and two unidentified polar lipids. Menaquinone 7 (MK-7) was the major respiratory quinone. The G+C content of the DNA of strain M2T2B15 was 52 mol%. The phenotypic, genotypic and phylogenetic data presented clearly indicate that strain M2T2B15 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is M2T2B15 (=KACC 14040 =NBRC 106324). Emended descriptions of the genus and of Vancanneyt 2006 are also proposed.
