The ionizing radiation toxicity becomes a major concern for the modern world, recent years, several special interest has been given to the research for the radiation resistant and the mechanisms of which the radiation resistant bacteria survive after the irradiation. In the current study, we have isolated strain DG31D was isolated from gamma ray-irradiated soil sample and showed resistant to gamma and UV radiation. The aim of this study is to understanding the radiation resistant mechanisms and their genomic features of the strain DG31D, which can be potentially used for the biotechnological application to degrade harmful soil contamination near the nuclear power stations and other radiation-affected areas. Strain DG31D showed resistant to UV and gamma radiation with D10 value of 10 kGy. The genome comprised of 4,820,793 bp with the G+C content of 51.4%. It contains the genomic features of enzymes involved in the nucleotide excision repair (NER) pathway that protect the damaged DNA.
