摘要：

Data from electrolytic respirometers were used to evaluate the kinetics of biodegradation of phenol, 4-chlorophenol, m-cresol, 2,4-dimethylphenol and 2,4-dinitrophenol through use of spreadsheets and nonlinear curve-fitting. The protocol is explained in detail. 4-Chlorophenol exhibited substrate inhibition kinetics and 2,4-dinitrophenol exhibited product inhibition kinetics. The others could be characterized by Monod kinetics. Values of the kinetic parameters describing biodegradation of each compound are presented. © 1990.
