Microbial depolymerization processes of exogenous type are studied by modeling and simulation. A mathematical model is transformed to remove a temporal factor of a degradation rate, and an inverse problem is solved numerically to determine the molecular factor using weight distributions with respect to the molecular weight before and after cultivation of a microbial consortium on plyethylene glycol. An initial value problem is solved numerically to simulate the transition of the weight distribution with a temporal factor that represents the microbial population. A novel technique is used to find suitable values of parameters that appear in the time factor of the degradation rate, and the numerical results are introduced.
