Singh, Vijay Murthy, Ganti Suryanarayana 2015-09-28T14:53:50Z 2015-09-28T14:53:50Z 10000-01-01 2006 2006 The controller maintained glucose concentration of <2.0% w/v in the fermenter throughout the SSF process. Reduced glucose concentrations minimize the osmotic shock to yeast and inhibit the growth of other competing microorganisms. Use of the optimal controller resulted in 50% reduction in glucoamylase amount required for the SSF process under varying operating conditions as compared to the standard SSF process. Optimal controller significantly improved final ethanol concentrations as compared to the conventional process without optimal controller under conditions of temperature and pH disturbances. Use of the optimal controller in conventional dry grind ethanol processes can result in estimated cost savings up to $1 million for a 151 million L/yr (40 million gal/yr) dry grind plant.
