A new apparatus for continuous ethanol production with internal separation of yeast cells is described. The removal of cell-free medium is accomplished by cake filtration through a thin layer of diatomaceous earth. By using a feeding pump connected with a level meter, fresh medium is supplied at the

β¦ Synopsis
The rate of fermentation of glucose by Saccharomyces uvarum in steadystate continuous culture in excess of substrates showed non-competltive inhibition kinetics with respect to ethanol. A model is presented which predicts that growth stops at a Finite ethanol concentration, which was calculated to be 95 g1-1 for the system used here. The observed maximum ethanol concentration in a single stage -1 continuous culture was 92 gl

In a low dilution rate study an unexpected pa-related inhibition of yeast fermentation was found. A higher volumetric rate of ethanol production occurred at lower pH values (2.8 to 3.2), suggesting a low optimum PH.
In order to minimize the adverse effect of CO 2 gas in a packed bed immobilized yeast reactor, a fluidized bed reactor was used for the continuous production of ethanol from glucose. Immobilized yeast was prepared by entrapping whole cells of Saccharomyces cerevisiae within a Caalginate matrix. It
