摘要
A Gram-stain-positive, coccus-shaped, facultatively anaerobic, non-motile bacterial strain, designated YIM S02567 T , was isolated from a forest soil sample collected from Gejiu City, Yunnan Province, southwest PR China. Growth was observed at 10–45 °C, at pH 6.0–9.5, in the presence of up to 4.0% (w/v) NaCl on R2A medium. The results of 16S rRNA gene sequence similarity analysis showed that strain YIM S02567 T was most closely related to the type strain of Brevilactibacter sinopodophylli (95.4%) and Propioniciclava tarda (94.7%), and phylogenetic analysis based on genome data showed that strain YIM S02567 T should be assigned to the genus Propioniciclava . The cell-wall diamino acid was meso -diaminopimelic acid. The major cellular fatty acids were identified as anteiso-C 15:0 and C 16:0 , and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, and two unidentified glycolipids. The predominant menaquinone was MK-9(H 4 ). The genomic DNA G + C content was 71.2 mol%. Based on the polyphasic taxonomic evidence, strain YIM S02567 T is assigned to a novel member of the genus Propioniciclava , for which the name Propioniciclava soli sp. nov., (type strain YIM S02567 T = CCTCC AB 2020128 T = CGMCC 1.18504 T = KCTC 49478 T ) is proposed. Furthermore, we propose the reclassification of Brevilactibacter as Propioniciclava gen. nov.
