Role of the DNA repair system in increasing the viability of E. coli cells under the action of small UV doses

Abstract

The authors studied the action of the ultraviolet light (UV) on the colony-forming ability of E.coli K12-HCR/sup +/ cultured in a meat infusion broth in the presence of glucose. An unusual shape of the curve indicates that the number of viable cells increases under the action of low UV doses. The experiment was repeated seven times, and each time the phenomenon was fully asserted (p 0.01). So it was suggested that low UV doses (about 140 erg/mm/sup 2/) activate the system of dark DNA repair (induction of the synthesis of repair enzymes) which repairs 'spontaneous' DNA defects and increases the number of colony-forming cells.
