Abstract

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and HS production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04 fell within the radiation of the cluster comprising species and clustered with ATCC 33299 (96.7 % sequence similarity); the similarity to sequences of other species within the family was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C, iso-C 3-OH and summed feature 4 (iso-C 2-OH and/or C 7). These chemotaxonomic data supported the affiliation of strain TR6-04 to the genus . However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04 (=KCTC 12579=LMG 23402=CCUG 52468) should be classified as the type strain of a novel species, for which the name sp. nov. is proposed.
