Abstract:
Five grams of urea and two milliliters of corn syrup were added into 1 liter ethanoldistilled wastewater with 8% solid dregs The activity of acid resistant ? amylase and glucoamylase produced by inoculated Aspergillus kawachii genetic engineering strain TR12 in the transformed liquid reached a level of 13 42U/mL and 246U/mL respectively after fermentation at 32℃ by the shaking flask for 70 hours The transformed liquid was circularly applied to the ethanol ingredient process without cooking room, not only it didn't influence the ethanol output and quality, but also it could efficiently reduce the pollution of ethanol distilled wastewater and the cost of ethanol production
