TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The hydrolyzing process is carried out in presence of an enzyme composition comprising alpha -amylase and a glucoamylase. The fermentation is carried out in the presence of yeast. The feedstock is chosen from wheat, rye, triticale, and barley. The wet milling is conducted after the hydrolyzing process. The wet milling is conducted with a rasp at 0-30 degrees C (more preferably 520 degrees C). The grinding process further includes crushing the starch containing feedstock before hydrolyzing. The ground feedstock before hydrolyzing is subjected to a temperature of 45-65 degrees C (preferably 50-60 degrees C) for 0.5-4 hours (preferably 1-3 hours). The alpha -amylase is obtained from Aspergillus kawachi. The glucoamylase is obtained from Aspergillus niger. The ethanol content of the fermented product is at least 15 weight% (preferably at least 18 weight%, more preferably at least 20 weight%). The ethanol product stream has an ethanol concentration of 95% or more (preferably 98% or more, more preferably 99% or more). A reaction vessel in which the glucose is fermented is heated with heat from the mechanical vapor recompression. EXAMPLE - Corn (55.43 kg) was mixed with water (46.6 kg) and fed to prefermenter. The prefermenter was heated to 40 degrees C and the pH was adjusted to 3.8 by adding 4M sulfuric acid. Subsequently, the temperature was raised to 60 degrees C after the addition of enzyme (Genzyme G998) (7.2 g). The mixture was stirred for 2 hours. The yeast mixture was prepared by dissolving 133.3 g of yeast in 400 ml of water at 30-35 degrees C. The solution was allowed to stand for 0.5 hours. Subsequently, the yeast mixture was added to the fermenter together with the effluent of the prefermenter. The temperature was reduced to 32 degrees C and the pH was set to 3.6 by adding 4M sulfuric acid. Then, urea (48 g), Stargen (RTM: not defined) (45 g), and GC106 (a protease obtained from Genencor International) (5.4 g) were added. The entire fermenter contents were allowed to react for 50 hours. Thus, the product stream comprising 16 volume% of ethanol was obtained.
