The surface growth of fungi was derived from the notion of equivalent symmetric tree model and was expressed for the two different growth phases, exponential phase and deceleration phase. PHBV degradation by fungi was expressed in terms of the degradation capability of a fungal hypha and the fraction of fungal biomass contributing to PHBV degradation. The proposed growth and degradation models simulated the experimental data obtained from fungal PHBV degradation in soil well and gave insight into fungal PHBV degradation process. (C) 2003 IMACS.
