Evaluation of structurally different carotenoids in Escherichia coli transformants as protectants against UV-B radiation.

G Sandmann1, S Kuhn, P Böger.   

Abstract

Escherichia coli 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 kinetics revealed that endogenous levels of neurosporene and beta-carotene protected E. coli against irradiation with UV-B. Zeaxanthin protected against only the photosensitized UV-B treatment. All other carotenoids were ineffective.
