A radiation‐resistant, Gram‐negative and pleomorphic bacterium (CON‐1) was isolated from a contaminated tryptone glucose yeast extract agar plate in the laboratory. It was red pigmented, nonmotile, nonsporulating, and aerobic, and contained MK‐8 as respiratory quinone. The cell wall of this bacterium contained ornithine. The major fatty acids were C16:0, C16:1, C17:0, C18:1 and iso C18:0. The DNA of CON‐1 had a G+C content of 70 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that CON‐1 exhibited a maximum similarity (94.72%) with Deinococcus grandis . Based on the genotypic, phenotypic and chemotaxonomic characteristics, the bacterium CON‐1 was identified as a new species of the genus Deinococcus , for which the name Deinococcus mumbaiensis sp. nov. is proposed. The type strain of D. mumbaiensis is CON‐1 (MTCC 7297 T =DSM 17424 T ).
