Genome of the extremely radiation-resistant bacterium Deinococcus radiodurans viewed from the perspective of comparative genomics

Article Abstract:

The genomic analysis in Deinococcus radiodurans reveal that the bacterium has developed protective features to resist extreme radiation and desiccation resistance in terms of specific superfamily of enzymes and proteins. Data also point out to the occurrence of numerous nucleotide repeats in the genome that are involved in stress resistance.

Engineering Deinococcus geothermalis for bioremediation of high-temperature radioactive waste environments

Article Abstract:

Research has been conducted on radiation-resistant thermophilic bacterium Deinococcus geothermalis engineered for the in situ radioactive waste bioremediation. The authors report that this bacterium can express Hg(II)-reducing functions cloned in pMD66, which has been used to functionally express cloned genes in D. radiodurans growing under chronic irradiation, at elevated temperatures and under chronic radiation, and can reduce other metal contaminants present in radioactive waste sites.
