Dermabacter jinjuensis sp. nov., a novel species of the genus Dermabacter isolated from a clinical specimen

A Gram-stain-positive, catalase-positive, facultatively anaerobic, non-motile, coryneform bacterium, designated strain 32 , was isolated from a closed pus sample from a patient having finger necrosis in Korea. Strain 32 was considered as representing a novel species according to its initial identification by matrix-assisted laser desorption/ionization-time-of-flight MS. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 32 belonged to the genus Dermabacter and was closely related to Dermabacter hominis DSM 7083 (=ATCC 49369 ) (98.34 % similarity). Optimal growth was observed at 30-40 °C and pH 7. Growth occurred in the presence of 0-6 % (w/v) NaCl. Menaquinones MK-8, MK-7 and MK-9 were the major respiratory quinones. The major polar lipids were phosphatidylethanolamine, phosphatidylcholine, glycolipid and two unknown lipids. The major cellular fatty acids were anteiso-C17 : 0, anteiso-C15 : 0, iso-C16 : 0 and iso-C15 : 0. The DNA G+C content of strain 32 was 62.58 mol%, and the mean level of DNA-DNA relatedness between strain 32 and D. hominis ATCC 49369 was 49±1.6 %. Based on the phenotypic and genotypic characteristics, strain 32 is confirmed to represent a novel species of the genus Dermabacter, for which the name Dermabacter jinjuensis sp. nov. is proposed. The type strain is 32 (=NCCP 16133 =DSM 101003 ).
