Title Deinococcus detaillensis sp. nov., isolated from humus soil in Antarctica.
Journal Arch Microbiol
Abstract A Gram-staining-positive, non-motile, coccus or short-rod-shaped bacterium, designated H1T, was isolated from a humus soil sample in the Detaille Island of Antarctica. The 16S rRNA gene sequence result indicated that strain H1T shared the highest 16S rRNA gene sequence identity with the type strain of Deinococcus alpinitundrae (96.2%). Growth of strain H1T occurred at 4-25 °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 C16:0, C17:0 cyclo and summed feature 3 (C16:1 ω7c/C16:1 ω6c). The polar lipids were aminoglycophospholipid, aminophospholipid, glycolipid and glycophospholipid. The cell wall peptidoglycan type was A3β. The genomic DNA G + C content was 61.3 mol%. The average nucleotide identity (ANI) between strain H1T and the closely related Deinococcus members was below the cut-off level (95-96%) for species identification. Based on the above results, strain H1T represents a novel species of the genus Deinococcus, for which the name Deinococcus detaillensis sp. nov. is proposed. Type strain is H1T (= CGMCC 1.13938T = JCM 33291T).
