摘要： In this study, a novel aerobic mesophilic bacterial strain with capable of degrading chitin, designated YIM B06366(T), was isolated and classified. The rod-shaped, Gram-stain-negative, on-spore-forming bacterium originated from rhizosphere soil sample collected in Kunming City, Yunnan Province, southwest PR China. Strain YIM B06366(T) exhibited growth at temperatures between 20 and 35 degrees C (optimum, 30 degrees C) and at pH 6.0-8.0 (optimum, pH 6.0). The analysis of 16S rRNA gene sequence similarity revealed that strain YIM B06366(T) was most closely related to type strain Chitinolyticbacter meiyuanensis SYBC-H1(T) (98.9%). Phylogenetic analysis based on genome data indicated that strain YIM B06366(T) should be assigned to the genus Chitinolyticbacter. The Average Nucleotide Identity (ANI) and digital DNA-DNA Hybridization (dDDH) values between strain YIM B06366(T) and the reference strain Chitinolyticbacter meiyuanensis SYBC-H1(T) were 84.4% and 27.7%, respectively. The major fatty acids included Summed Feature 3 (C-16:1 omega 6c/C-16:1 omega 7c), Summed Feature 8 (C-18:1 omega 6c/C-18:1 omega 7c), and C-16:0. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, aminophospholipids, and two unidentified phospholipids. The predominant menaquinone was Q-8, and the genomic DNA G + C content was 64.1%. Considering the polyphasic taxonomic evidence, strain YIM B06366(T) is proposed as a novel species within the genus Chitinolyticbacter, named Chitinolyticbacter albus sp. nov. (type strain YIM B06366(T) = KCTC 92434(T) = CCTCC AB 2022163(T)).
