Description
In this work the authors studied inactivation of bacteriophage lambda11 and three strains of Escherichia coli K12 under high-intensity picosecond laser UV irradiation. With the rise of UV irradiation intensity from 1010 W/m2 to 1013 W/m2 the photoresistance of these objects sharply increased: for lambda11 phage by 33-67 times depending on host-cell strain chosen, for different strains of E. coli by 13-476 times. Under picosecond UV irradiation of lambda11 the single-quantum and two-quantum photolesions made comparable contributions to the total lethal photoproduct. In the case of E. coli it was mainly two-quantum photolesions that brought about picosecond UV inactivation. (Auth.)
