A Gram-staining negative, aerobic, non-motile, rod-shaped bacterial strain, designated YS-37T, was isolated from soil in a manganese factory, People’s Republic of China. Based on 16S rRNA gene sequence analysis, strain YS-37T was most closely related to Lysobacter pocheonensis Gsoil 193T (97.0%), Lysobacter dokdonensis DS-58T (96.0%) and Lysobacter daecheongensis Dae08T (95.8%) and grouped together with L. pocheonensis Gsoil 193T and Lysobacter dokdonensis DS-58T. The DNA–DNA hybridization value between strain YS-37T and L. pocheonensis KCTC 12624T was 43.3% (± 1). The major respiratory quinone of strain YS-37T was ubiquinone-8, and the polar lipids were diphosphatidylglycerol, phosphatidylethanolamine,
phosphatidylglycerol, phospholipid, phosphatidylmethylethaolamine and two unknown lipids. Its major
cellular fatty acids (> 5%) were iso-C15:0, iso-C17:1ω9c, iso-C16:0, iso-C11:0 3-OH and iso-C11:0 and the G + C content of the genomic DNA was 67.1 mol%. Strain YS-37T also showed some biophysical and biochemical differences with the related strains, especially in hydrolysis of casein. The results demonstrated that strain YS-37T belongs to genus Lysobacter and represents a novel Lysobacter species for which the name Lysobacter tongrenensis sp. nov. is proposed. The type strain is YS-37T (= CCTCC AB 2016052T = KCTC 52206T).
