Abstract
Deinococcus radiodurans is highly resistant to reactive oxygen species (ROS). The antioxidant effect of carotenoids in D. radiodurans was investigated by using a targeted mutation of the phytoene synthase gene to block the carotenoid synthesis pathway and by evaluating the survival of cells under environmental stresses. The colorless mutant R1DeltacrtB of D. radiodurans failed to synthesize carotenoids, and was more sensitive to ionizing...
