Abstract

An aerobic, yellow-pigmented, facultatively methylotrophic, Gram-staining-negative, non-spore-forming bacterium, designated strain Gm-149, was isolated from the rhizosphere of cultivated soybean in India. Cells were motile by gliding. The predominant cellular fatty acids were iso-C, summed feature 3 (comprising iso-C 2-OH and/or C 7), C 3-OH and anteiso-C, and the major isoprenoid quinone was MK-6. The G+C content of the genomic DNA of strain Gm-149 was 35.6 mol%. Comparative 16S rRNA gene sequence analysis showed that strain Gm-149 formed a distinct phyletic line within the genus . Based on levels of pairwise 16S rRNA gene sequence similarity, strain Gm-149 was related most closely to the type strain of (97.1 %), but the level of DNA–DNA relatedness between these two strains was about 11.2 %. On the basis of phenotypic and genotypic data, strain Gm-149 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is Gm-149 (=ICMP 17618=NBRC 105008).
