摘要： A novel Gram-stain-negative, aerobic strain, designated Y22(T), was isolated from peanut field soil in Laoshan Mountain in China. Cells of strain Y22(T)were rod-shaped and motile by a single flagellum. The strain was found to be oxidase- and catalase-positive. 16S rRNA gene sequence based on phylogenetic analysis indicated that strain Y22(T)belonged to the genusPseudomonas, and showed the highest 16S rRNA gene sequence similarity of 99.0% toPseudomonas pelagiaJCM 15562(T), followed byPseudomonas salinaJCM 19469(T)(98.4%),Pseudomonas sabulinigriJCM 14963(T)(97.9%),Pseudomonas bauzanensisCGMCC 1.9095(T)(97.6%) andPseudomonas litoralisKCTC23093(T)(97.5%). The phylogenetic analysis based on multilocus sequence analyses with concatenated 16S rRNA,gyrB,rpoDandrpoBgenes indicated that strain Y22(T)belonged toPseudomonas pertucinogenalineage. The average nucleotide identity scores between strain Y22(T)and closely related species were 74.6-82.8%, and the Genome-to-Genome Distance Calculator scores were 16.4-44.9%. The predominant cellular fatty acids of strain Y22(T)were C-18:1 omega 7c (29.6%), C(17:0)cyclo (17.5%) and summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c) (17.4%). The genomic DNA G+C content was 57.9 mol%. On the basis of phenotypic characteristics, phylogenetic analyses and in silico DNA-DNA relatedness, a novel species,Pseudomonas laoshanensissp. nov. is proposed. The type strain is Y22(T)(= JCM 32580(T) = KCTC 62385(T) = CGMCC 1.16552(T)).
