Paper Abstract

Influence of laser irradiation and low-coherent speckles on the colonies grows of Pseudomonas Aeruginosa is studied. It has been demonstrated that effects of light on the inhibition or re-activation of cells are connected with speckle dynamics. The regimes of cell suspension perfusion with purpose of devitalization of bacteria are found on the base of experimental investigations. Mathematical model of interaction of low-coherent laser radiation with bacteria suspension has been developed. Parameters of mathematical model have been identified. Computer simulations of the processes of laser-cells interaction have been carried out.
