Abstract:
This paper compares four growth models (Logistic Model, Gompertz Model, Richards Model and Stannard Model) using the experimental data of wastewater treatment from a single sell protein production with Bacillus subtilis in order to describe bacterial biomass growth. One model was used to describe carbohydrate consumption during the bacterial fermentation. This study was carried at the Department of Biotechnology (Mendeleev University of Chemical Technology of Russia) as part of deproteinized sunflower meal bioconversion into a highly added value product research. The temporal profiles of carbohydrates unmetabolized during single cell protein production with the yeasts, and CFU/mL were modelled with a set of ordinary differential equations solved using MATLAB software. The models were validated by the experimental data based on goodness of fit criteria; R2, MSE, and SD values. The coherence between the models and experimental results demonstrated that the models were reasonable for the prediction of the fermentation process dynamic behavior. The models gave more information about the operation conditions of the fermentation and they could be applied for further development and scaling of wastewater treatment during the single cell protein production.
