Abstract

A method for production of lactic acid bacteria by utilizing ethanol industrial yellow water includes collection and treatment of the ethanol industrial yellow water, cultivation of the lactic acid bacteria in the ethanol industrial yellow water, and receiving and preparation of the lactic acid bacteria. The method for production of the lactic acid bacteria by utilizing the ethanol industrial yellow water not only can make full use of the ethanol industrial yellow water, reduce the treatment cost of the yellow water, optimize comprehensive utilization of the yellow water and improve the ecological environment, but also can expand sources of a nutrition substrate in a conventional lactic acid bacteria production, lower the production costs and expand the application scope of lactic acid bacteria.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of yellow water in the alcohol industry and the field of microorganism cultivation, in particular to the use of yellow water in the alcohol industry for microorganism cultivation. Background technique [0002] Alcohol industry is an important energy industry in my country, but huge by-products will be produced in the process of alcohol production, among which solid components such as distiller's grains and part of yellow water can continue to produce feed materials such as DDGS and be reused, and most of them are The yellow water has not been well utilized. Yellow water is a liquid substance rich in various nutrients discharged during the production of alcohol. Yellow water is rich in organic acids (especially carboxylic acids such as lactic acid, butyric acid, caproic acid, and acetic acid), alcohols, aldehydes, At the same time, it also contains amino acids, sugars, alcohol, humus, yeast ...
