Comparison of various kinetic models for batch biodegradation of leachate from tobacco waste composting

This paper presents kinetic analyses of biodegradation of organic matter from leachate which is produced during the composting process of tobacco waste. Four different kinetic models were applied to the data. The kinetic analysis was performed with traditional Monod model, modified Monod model with endogenous metabolism, Haldane model and Haldane model which is expanded with endogenous metabolic consumption and called Endo- Haldane model. Kinetic parameters for each model were determined using differential analysis and the Nelder-Mead method of nonlinear regression. The lowest deviations and very good matches with experimental data were achieved using Endo-Haldane model. This fact pointed out that this model best described the process of biodegradation of leachate from tobacco waste composting. This is due to fact that this model incorporates both, effects of inhibition and endogenous metabolism.
