Abstract:
Four gamma- and UV-radiation-resistant bacterial strains, designated TDMA-24 T , TDMA-24-2, TDMA-24-3 and TDMA-24-4, were isolated from a fresh-water sample collected at Misasa, Tottori, Japan. Cells of these strains were Gram-reaction-positive, non-motile, non-spore-forming, rod-shaped and formed red colonies. The genomic DNA G+C contents ranged from 70.5 to 70.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel isolates belong to the genus Deinococcus , the highest sequence similarities being with Deinococcus aquaticus PB314 T (98 %) and Deinococcus caeni Ho-08 T (97 %). The polar lipid profile of strain TDMA-24 T comprised three unidentified phosphoglycolipids, five unidentified glycolipids and seven unidentified polar lipids. MK-8 was the predominant respiratory quinone. Major fatty acids were iso-C 15 : 0 , C 15 : 1 ω6 c , C 15 : 0 , C 16 : 0 and summed feature 3 (iso-C 15 : 0 2-OH and/or C 16 : 1 ω7 c ). On the basis of their phylogenetic positions and chemotaxonomic and phenotypic characteristics, the novel isolates represent a novel species of the genus Deinococcus , for which the name Deinococcus depolymerans sp. nov. is proposed. The type strain is TDMA-24 T ( = JCM 14369 T = NBRC 102115 T = CCUG 53609 T ).
