Abstract

A bacterial strain, RS-LYSO-3T, was isolated from tobacco-cultivated soil, collected near Chuxiong, Yunnan province, southwestern China. RS-LYSO-3T could effectively inhibit the invasion of powdery mildew on tobacco. The colonies of RS-LYSO-3T 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 329T. Chemotaxonomic data showed that RS-LYSO-3T possesses a quinone system with Q-8, and iso-C16 : 0, summed feature 9 and iso-C15 : 0 as the predominant fatty acids, all of which support the affiliation of RS-LYSO-3T to the genus Lysobacter. The results of DNA-DNA hybridization, physiological and biochemical tests clearly proved that RS-LYSO-3T 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-3T (=CCIC 23922T=JCM 31042T).
