ABSTRACT
A Gram-stain-positive, rod-shaped, non-motile bacterial strain, designated JW-1T, was isolated from activated sludge collected from the outlet of an aeration tank in a prometryn-manufacturing plant, located in Binzhou City, Shandong province, PR China. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain JW-1T belongs to the genus Leucobacter and its closest neighbours are 'Leucobacter kyeonggiensis' F3-P9 (98.95â% similarity), Leucobacter celer subsp. astrifaciens CBX151T (98.62â%), Leucobacter celer subsp. celer NAL101T (98.53â%), Leucobacter chromiiresistens JG31T (97.86â%) and Leucobacter chironomi DSM 19883T (97.37â%). DNA-DNA hybridization values with the above strains were <55â%. The DNA G+C content of strain JW-1T was 72.6 mol%. The major fatty acids of strain JW-1T were iso-C16ââ0, anteiso-C15ââ0, anteiso-C17ââ0 and iso-C15ââ0. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and glycolipid. The predominant menaquinone was MK-11. The cell wall amino acids were 2,4-diaminobutyric acid, alanine, glutamic acid, glycine and threonine. Based on the molecular and chemotaxonomic data, as well as the physiological and biochemical characteristics, strain JW-1T is considered to represent a novel species of the genus Leucobacter, for which the name Leucobacter triazinivorans is proposed. The type strain is JW-1T (=DSM 105188T=LMG 30083T).
