Abstract:
Saccharomyces cerevisiae is known as the most widely used eukaryotic microorganism for biological studies. In present study, cell growth profile of Saccharomyces cerevisiae in a batchsubmerged culture was evaluated with three different non-structured kinetic models. Fitness assessmentof experimental data on cell growth by models was performed using the curve-fitting tool in Excel andMat-lab software. Obtained results showed Verhulst kinetic model with R2 equal to 0.97 was the mostappropriate to describe the biomass growth rate of Saccharomyces cerevisiae. Maximum specific cell growth rate by Verhulst model was 0.59 h 1. Other kinetic constants were also determined for all the studied models
