Abstract

Abstract: Based on the theory of substrate permeation through the cytoplasmic membrane, and
considering the effect of initial concentration of substrate, a new kinetic model of phenol
degradation process was proposed. Comparing with the widely used Haldane model, which is
greatly dependent on the initial phenol concentration, our model can be used to simulate
the phenol degradation process in a wide range of initial phenol concentration by using
only one set of model parameters. Therefore, this new kinetic model has much more potential
applications to industrial design and operation.

Key words: substrate permeation, specific degradation rate, phenol, kinetics
