Lysobacter zhanggongensis sp. nov. Isolated from a Pit Mud.

The Gram-stain-negative, rod-shaped and non-motile bacterial strain, designated ZGLJ7-1T , was isolated from a pit mud. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain ZGLJ7-1T was related to the genus Lysobacter and had the highest 16S rRNA gene sequence similarity with the type strain of Lysobacter arseniciresistens ZS79T (97.4%). The predominant cellular fatty acids were iso-C15:0 , iso-C17:1 ω9c, iso-C11:0 and iso-C11:0 3-OH. Strain ZGLJ7-1T 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 ZGLJ7-1T was 69.5 mol%. Strain ZGLJ7-1T shared DNA relatedness with 35% Lysobacter arseniciresistens CGMCC 1.10752T . Combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies demonstrated that the strain ZGLJ7-1T is a representative of a novel species of the genus Lysobacter, for which we propose the name Lysobacter zhanggongensis sp. nov. (type strain ZGLJ7-1T  = KACC 18547T  = CGMCC 1.15404T ).
