Abstract excerpt
Mycobacterium carotenum is more tolerant to the action of hydrogen peroxide than its white, carotenoidless mutant. This elevated tolerance to H2O2 correlates with a higher content of DNA, RNA, and polysaccharides in the cells; it is not related to the content of proteins and lipids, or to the level of the catalase and peroxidase activity.
