Abstract

ABSTRACT Escherichia coli cells transformed with several carotenogenic genes to mediate the formation of ζ-carotene, neurosporene, lycopene, β-carotene, and zeaxanthin were exposed to UV-B radiation. Short-term kinetics revealed that endogenous levels of neurosporene and β-carotene protected E. coli against irradiation with UV-B. Zeaxanthin protected against only the photosensitized UV-B treatment. All other carotenoids were ineffective.
