The laser irradiation effect of nutrient media solutions on their microstructure and, as a result, on the dynamics of bacterial growth in photomodified media is considered in the article. It is experimentally shown that the growth rate of bacteria varies depending on the irradiation media time, that allows us to control the dynamics of bacterial cultures.
