摘要

This paper presents a simulation technique of yeast cultivation and ethanol fermentation on acommercially available process simulator. In general, the simulation of microorganism cultivation on the processsimulator is not possible because a material data of the microorganism is not registered in the simulator. If all of thedata required is collected and installed to the simulator, the simulation of the microorganism cultivation will beachieved on it. Yeast which is a widely known in industrial field was chosen as a model microorganism. The data ofyeast was collected by analytical measurement and literature survey, followed by a composition of model yeast andreaction formulas were determined. All data associated the yeast was completely installed in to the simulator. Processof the yeast cultivation and ethanol fermentation was demonstrated on the simulator as a case study. The success ofthe simulation of the case study was confirmed. Estimation of input substrate quantity and prediction of generatedheat amount of microbial reaction become possible on the proposed method. This method can provide diversificationand advancement of simulation technique for process evaluation associated microbial reaction.
