Study of growth kinetic and modeling of ethanol production by Saccharomyces cerevisae

There is a growing interest in bioethanol as biofuel since it has the possibility to be the potential substitute for fossil fuels. Ethanol batch fermentation of Saccharomyces cerevisiae strain was carried out in 10 L stirred tank bioreactor for 72 h at 0.075 vvm of aeration and 75 rpm of agitation...
