Description

technical field

[0001] The invention belongs to the technical field of fermentation, and in particular relates to a method for preparing ethanol by using Pichia stipitis to ferment mixed pentose and hexose sugars. Background technique

[0002] In the field of chemical industry, ethanol (commonly known as alcohol) is an important industrial raw material, which is widely used in chemical industry, food, beverage industry, military industry, daily chemical industry, medicine and health, etc., and ethanol is an excellent fuel (its combustion The value reaches 26900 kJ / kg), which can improve the fuel quality[]. Today, in the fermentation industry, the bioconversion of Saccharomyces cerevisiae is mainly used to produce ethanol.

[0003] With the intensification of the global energy crisis, people pay more and more attention to the development and utilization of fuel ethanol. Traditional ethanol production using starch as raw material consumes a large amount of food, increasing t...
