Abstract

We have suggested a mathematical model of bio-optical nonlinearities for the suspensions of motile microorganisms (MO). Modeling of photophobic and photokinetic types of the photoresponse of MO suspensions allow us to predict effects of aggregation and 'hole burning' in the spatial distribution of MO concentration. Theoretical description of nonlinear diffraction may help with the diagnosis of the vitality of MO culture and for characterization of photomovement.
