摘要: A novel actinobacterial strain, designated SDT, was isolated from rhizosphere soil of Chinese cabbage in Shandong province, China. The cells were aerobic, Gram-staining-positive, oxidase-and catalase-positive, short rods and formed white colonies on trypticase soy agar. The cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid and alanine, glutamic acid and leucine. Diphosphatidylglycerol was the predominant polar lipid. The predominant cellular fatty acid was C-18 : (1)omega 9c; minor components were anteiso-C-15 (: 0) and anteiso-C-17 (:) (0). The only isoprenoid quinone was demethylnnenaquinone 7 (DMK-7), and the DNA G+C content was 72.7 mol%. Based on the full-length 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain SDT were Patulibacter medicamentivorans DSM 25962(T) (96.9 %), Patulibacter minatonensis DSM 18081(T) (96.7 %), Patulibacter americanus DSM 16676(T) (96.2%) and Patulibacter ginsengiterrae DSM 25990(T) (95.9%). Considering combined phenotypic and genotypic characteristics, it is proposed that strain SDT represents a novel species of the genus Patulibacter, for which the name Patulibacter brassicae sp. nov. is proposed. The type strain is SDT (=CICC 24108(T)=KCTC 39817(T)).
