Abstract

A novel bacterium, CAI-18b, was isolated from a bioreactor that treated landfill leachate using an oligotrophic growth medium. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain CAI-18b is a member of the genus , showing 97.1 % pairwise similarity to H359, 96.4 % to 1351, 96.4 % to MDT1-10-3 and 96.0 % to MCC P1. Strain CAI-18b was rod-shaped, motile, oxidase- and catalase-positive. The predominant fatty acids were iso-C (24.1 %) and iso-C I (22.3 %), the major respiratory quinone was MK-7, and the predominant polar lipids were phosphatidylethanolamine and an unknown aminophospholipid. The G+C content of the genomic DNA of strain CAI-18b was 50.7 mol%. The novel bacterium can be distinguished from related type strains based on its ability to assimilate -acetylglucosamine and gentiobiose. On the basis of the phenotypic, chemotaxonomic and molecular data, strain CAI-18b represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is CAI-18b (=DSM 29854=NCAIM B.02614).
