Modelling and scalling up for single - cell protein production in continuous bioreactor

Interest in searching for new sources of food has increased exponentially during the last 40 years. In this study, modelling of continuous strred tank bioreactor is carried out from experimental results and then a bioreactor in pilot scale is designed for production of 40 kg S.C.P. per day. For modelling of bioreactor in constant temperature and pressure, balance equation of cell mass, methanol, oxygen and carbon dioxide are developed. Atfer disoliving of equations by fourth order runge , the influence of both kinetic and transport parameters on dissolved oxygen, biomass. and methanol concentration were studied. From comparing of experimental and theoric results optimum parameters were obtained. For designing bioreactor in pilot scale from optimum parameters, size. of bioreactor and other epuipents were obtained. Then other parameters from different bases for scaling up were obtained.
