A Gram-staining-negative, aerobic, rod-shaped, non-spore-forming bacterial strain, Ca-34(T), was isolated from nodules of chickpea (Cicer arietinum) in Pakistan and studied for its taxonomic affiliation. The almost full-length 16S rRNA gene sequence showed highest similarities to those of strains of the genus Ochrobactrum. Based on results of MALDI-TOF MS and 16S rRNA gene sequence similarity (98.6%), strain Ca-34(T) and Ochrobactrum intermedium LMG 3301(T) are phylogenetic neighbours; the two strains shared DNA DNA relatedness of 64%. The fatty acid profile [predominantly C(18:1)omega 7c (67.7%) and C(19:0) cyclo omega 8c (19.6%)] also supported the genus affiliation. Metabolically, strain Ca-34(T) differed from other type strains of Ochrobactrum in many reactions and from all type strains in testing positive for gelatin hydrolysis and in testing negative for assimilation of alaninamide and L-threonine. Based on phenotypic and genotypic data, we conclude that strain Ca-34(T) represents a novel species, for which we propose the name Ochrobactrum ciceri sp. nov. (type strain Ca-34(T) =DSM 22292(T) =CCUG 57879(T)).
