ABSTRACT:
A brief critical analysis of kinetic models is
presented, particularly the quadratic model (QM), highlighting their strengths
and weaknesses. A generalized quadratic model (GQM) is proposed that can
accommodate the experimental observation that the degradation rate is non-zero
in the limit of zero substrate concentration. The limits of this model are
outlined by comparison with a more extended kinetic scheme.
