The processes of laser photoinduced modification of nutrient media and antibiotic solutions are considered. It is shown experimentally that the growth of colonies number is slower on the irradiated medium. The impact of laser radiation on the antibiotic activity is also studied experimentally. It is found that the laser-induced photomodification can affect the antimicrobial activity of the medicinal preparations.
