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-17:1 omega 9c, iso-C-11:0 and iso-C(11:0)3-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)).
