ABSTRACT
Ultraviolet irradiated E. Coli. B/r cells recover from UV damage when the cells are kept in dark due to dark repair mechanism. Photoprotection by illumination of the cells in near UV light prior to the exposure to UV light increases the capacity of the cells to induce L-arabinose isomerase synthesis in response to inducer, L-arabinose. The survival of the cells is dependent on the UV dose. The increased synthesis of L-arabinose isomerase after photoprotection is due to the amount of cyclic AMP in the cells.
