Abstract

In this work, established models of renowned scholars in fermentation technology are analytically solved. Fermentation experiments were also performed on the production of ethanol and bi-omass from substrate (grain i.e. malted barley) with time and used to validate the analytical solutions of the scholarly models. The result shows that the mod-els were real and true to life as they gave coefficient of correlation of 99.63%. It is also observed that dur-ing this fermentation, there was serious interaction between substrate concentration and ethanol concen-tration, substrate concentration and biomass concen-tration. From this model, it was found that the yield of ethanol (product) was 79.34%, yield of biomass was 43.8%, initial ethanol before fermentation was 1.45g/lit. Substrate at the beginning, S0= 8.114g/lit. and initial biomass X0 was 0.8098g/lit. This result can be applied in fermentation planning in any brew-ing company of research centers to predict variation of certain parameters.
