Demonstration of Numerical Techniques for microbial depolymerization process of xenobiotic polymer


In a microbial depolymerization process, microorganisms utilize a polymer as a carbon source for growth and activity. This fact leads to a model that involves a time factor and a molecular factor of a degradation rate. Experimental results are introduced into inverse problem of those factors. Once inverse problems are solved numerically, a microbial depolymerization process is simulated. Those techniques are demonstrated with an example.
