Genome Sequence of the Radiation-Resistant Bacterium Deinococcus radiophilus ATCC 27603T

The pigmented bacterium Deinococcus radiophilus, which is highly resistant to radiation exposure, was first isolated from irradiated lizardfish. We report a genome assembly of D. radiophilus UWO 1055T (=ATCC 27603T), with a predicted genome size of 2.7 Mbp (62.66% G+C content). A number of CRISPR-associated proteins and two CRISPR arrays were identified.

Isolation of Deinococcus Species from Commercial Oyster Extract

ABSTRACT Deinococci with radiation resistance greater than that ofDeinococcus radiophilus (ATCC 27603) were isolated from three commercial oyster extracts stored at 4, 20, and 30°C. During storage the number of other bacteria declined and deinococci became the predominant group in the microflora, particularly at 20°C, although at 30°C the number of deinococci as well rapidly declined. The results suggest that the natural habitat of deinococci is an aerobic environment containing a slightly elevated saline content, soluble protein, and low sugar levels.
