Abstract

A stationary problem of the oxidative action of a representative biofilm is formulated taking into account the nonlinear kinetics of substrate utilization, which reflects its limitation and inhibition. Two characteristic situations are sequentially considered - high initial content of the substrate, relatively low oxidation rate (no inert zone); low substrate content, high oxidation rate (inert zone exists). The exact solution of the mathematical problem are obtained and compared. A number of special cases are considered. The subject of quantitative analysis was the consequences of biooxidation for different parts of the biofilm and its productivity.
