Abstract

Two yellow-pigmented, Gram-stain-positive, aerobic, motile, short rod-shaped bacteria were isolated from natural teak tree rhizosphere soil and their taxonomic positions were determined by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strains TG-S248 and TG-S240 formed a distinct phyletic line within the genus . 16S rRNA gene sequence analysis of strain TG-S248 with sequences from DB 102, VKM Ac-1401, DB 103, DSM 20146 and subsp. JCM 9733 revealed pairwise similarities ranging from 98.7 to 99.1 %. The major fatty acids were anteiso-C, anteiso-C and iso-C. The G+C content of the DNA of the type strain was 69.4 mol%. DNA–DNA hybridization experiments revealed low levels of DNA–DNA relatedness (32 % or less) between strain TG-S248 and its closest relatives. Based on differences in phenotypic and genotypic characteristics, strain TG-S248 (=LMG 24767 =JCM 15679) is designated the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
