Rate equations for the vigorous stationary phase fermentation of citric acid bySaccharomycopsis lipolytica

Rate equations for the vigorous stationary phase fermentation of citric acid by Saccharomycopsis lipolytica were determined using a continuous-stirred-tank-membrane-reactor system. The rate of glucose consumption is independent of fermentation broth glucose concentration for the range of 1-25 g cellulose/L. The rate of glucose consumption is noncompetitively inhibited by citric acid with a product inhibition constant of 235 g citrate/L. The rate of citrate production is proportional to the logarithm of the glucose concentration.
