Abstract
Escherichia call cells transformed with several carotenogenic genes to mediate the formation of zeta-carotene, neurosporene, lycopene, beta- carotene, and zeaxanthin were exposed to UV-B radiation. Short-term ki netics revealed that endogenous levels of neurosporene and beta-carote ne protected E. coli against irradiation with UV-B. Zeaxanthin protect ed against only the photosensitized UV-B treatment. All other caroteno ids were ineffective.
