| ABSTRACT |
A set of equations is suggested to describe the kinetics of degradation of organic compounds applied to soils and the kinetics of growth of the involved microorganisms:
-dx/dt=jx+kxm
dm/dt=-fm+gxm
where x is the concentration of organic compound at time t, m is the number of microorganisms capable of degrading the organic compound at time t, while j, k, f and g are positive constants. This model can satisfactorily be used to explain the degradation curve of organic compounds and the growth curve of the involved microorganisms. |
