Lysobacter zhanggongensis sp. nov. Isolated from a Pit Mud

The Gram-stain-negative, rod-shaped and non-motile bacterial strain, designated ZGLJ7-1^T, was isolated from a pit mud. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain ZGLJ7-1^T was related to the genus Lysobacter and had the highest 16S rRNA gene sequence similarity with the type strain of Lysobacter arseniciresistens ZS79^T (97.4%). The predominant cellular fatty acids were iso-C_15:0, iso-C_17:1ω9c, iso-C_11:0 and iso-C_11:03-OH. Strain ZGLJ7-1^T had Q-8 as the predominant ubiquinone. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unidentified phospholipid, two unidentified aminolipids and two unidentified lipids. The genomic DNA G+C content of strain ZGLJ7-1^T was 69.5 mol%. Strain ZGLJ7-1^T shared DNA relatedness with 35% Lysobacter arseniciresistens CGMCC 1.10752^T. Combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies demonstrated that the strain ZGLJ7-1^T is a representative of a novel species of the genus Lysobacter, for which we propose the name Lysobacter zhanggongensis sp. nov. (type strain ZGLJ7-1^T = KACC 18547^T = CGMCC 1.15404^T).
