Abstract
In the context of studying the possibility of inactivation of pathogenic microorganisms, the dynamic transmission spectra of femtosecond laser radiation in the mid-IR range by bacteria of the Pseudomonaus aeruginosa culture planted on a silicon substrate were investigated. Irradiation revealed a blue shift in the characteristic absorption bands of bacteria, indicating the breaking of hydrogen bonds responsible for the formation of the secondary and tertiary structure of the proteins.
