A bacterial strain, RS-LYSO-3(T), was isolated from tobacco-cultivated soil, collected near Chuxiong, Yunnan province, southwestern China. RS-LYSO-3(T) could effectively inhibit the invasion of powdery mildew on tobacco. The colonies of RS-LYSO-3(T) were pale yellow, and its cells were Gram-stain-negative and rod-shaped, with 68 mol% DNA G+C content. Gene sequence analysis for its 16S rRNA gene revealed the highest similarity (97.78 %) with that of Lysobacter spongiicolaKMM 329(T). Chemotaxonomic data showed that RS-LYSO-3(T) possesses a quinone system with Q-8, and iso-C-16:0, summed feature 9 and iso-C-15:0 as the predominant fatty acids, all of which support the affiliation of RS-LYSO-3(T) to the genus Lysobacter. The results of DNA-DNA hybridization, physiological and biochemical tests clearly proved that RS-LYSO-3(T) is a representative of a novel species of the genus Lysobacter, for which the name Lysobacter erysipheresistens sp. nov. is proposed. The type strain is RS-LYSO-3(T) (=CCIC 23922(T) = JCM 31042(T)).
