Segnochrobactrum spirostomi gen. nov., sp. nov., isolated from the ciliate Spirostomum yagiui and description of a novel family, Segnochrobactraceae fam. nov. within the order Rhizobiales of the class Alphaproteobacteria.

ABSTRACT: A bacterial strain, designated Sp-1^T, was isolated from the heterotrich ciliate Spirostomum yagiui collected from a reservoir located in Ulsan, Republic of Korea. Cells of Sp-1^T were Gram stain-negative, rod-shaped, non-spore-forming, non-motile and contained poly-β-hydroxybutyrate granules. Phylogenetic analyses based on 16S rRNA gene sequences indicated that Sp-1^T constituted a distinct phylogenetic lineage within different families in the order Rhizobiales with a pairwise sequence similarity of 95 % to the species of the genus Ochrobactrum: Ochrobactrum anthropi ATCC 49188^T and Ochrobactrum cytisi ESC1^T (family Brucellaceae). The major cellular fatty acids were C_19 : 0 cyclo ω8c (
