TY - JOUR AU - Kumar, Deepak AU - Singh, Vijay PY - 2016 DA - 2016/10/24 TI - Dry-grind processing using amylase corn and superior yeast to reduce the exogenous enzyme requirements in bioethanol production JO - Biotechnology for Biofuels SP - 228 VL - 9 IS - 1 AB - Conventional corn dry-grind ethanol production process requires exogenous alpha and glucoamylases enzymes to breakdown starch into glucose, which is fermented to ethanol by yeast. This study evaluates the potential use of new genetically engineered corn and yeast, which can eliminate or minimize the use of these external enzymes, improve the economics and process efficiencies, and simplify the process. An approach of in situ ethanol removal during fermentation was also investigated for its potential to improve the efficiency of high-solid fermentation, which can significantly reduce the downstream ethanol and co-product recovery cost.
