Abstract
A novel, yellow-pigmented bacterium, designated strain MO64T, was isolated from the rhizoplane of field-grown soybean, collected from an experimental plot at Coimbatore, India. Cells were Gram-reaction-negative, motile, non-spore-forming rods that produced yellow-pigmented colonies on R2A agar. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain MO64T belonged to the genus Rhodanobacter . Strain MO64T was related most closely to Rhodanobacter ginsengisoli GR17-7T (98.0 % 16S rRNA gene sequence similarity), Rhodanobacter spathiphylli B39T (97.9 %), Rhodanobacter panaciterrae LnR5-47T (97.7 %), Rhodanobacter terrae GP18-1T (97.6 %), Rhodanobacter soli DCY45T (97.3 %) and Rhodanobacter caeni MJ01T (97.2 %); levels of similarity to the type strains of all other recognized species of the genus Rhodanobacter were less than 97.0 %. Chemotaxonomic data (Q-8 as the predominant ubiquinone, and iso-C16 : 0, iso-C15 : 0, C17 : 0 cyclo, iso-C17 : 1ω9c, iso-C17 : 0 and iso-C11 : 0 as the major fatty acids) also supported the affiliation of strain MO64T with the genus Rhodanobacter . The G+C content of the genomic DNA was 64 mol%. The results of DNA–DNA hybridization and phenotypic analysis showed that strain MO64T can be distinguished from all known species of the genus Rhodanobacter and therefore represents a novel species of the genus, for which the name Rhodanobacter glycinis sp. nov. is proposed. The type strain is MO64T ( = ICMP 17626T = NBRC 105007T).
