摘要： A Gram-staining-positive, non-motile, coccus or short-rod-shaped bacterium, designated H1(T), was isolated from a humus soil sample in the Detaille Island of Antarctica. The 16S rRNA gene sequence result indicated that strain H1(T)shared the highest 16S rRNA gene sequence identity with the type strain ofDeinococcus alpinitundrae(96.2%). Growth of strain H1(T)occurred at 4-25 degrees C, pH 6.0-8.0 and in the presence of 0-1.0% NaCl (w/v). The respiratory quinone was MK-8. The major fatty acids were C-16:0, C(17:0)cyclo and summed feature 3 (C-16:1 omega 7c/C-16:1 omega 6c). The polar lipids were aminoglycophospholipid, aminophospholipid, glycolipid and glycophospholipid. The cell wall peptidoglycan type was A3 beta. The genomic DNA G + C content was 61.3 mol%. The average nucleotide identity (ANI) between strain H1(T)and the closely relatedDeinococcusmembers was below the cut-off level (95-96%) for species identification. Based on the above results, strain H1(T)represents a novel species of the genusDeinococcus, for which the nameDeinococcus detaillensissp. nov. is proposed. Type strain is H1(T)(= CGMCC 1.13938(T) = JCM 33291(T)).
