Culture medium for improving culture temperature of industrial microorganisms and preparation method thereof

Abstract

The invention relates to a culture medium for improving the culture temperature of industrial microorganisms by using carbon nano material and a preparation method thereof. The culture and the fermentation of microorganisms under high temperature condition are realized by adding a nanometer carbon material in a culture medium of the microorganisms so as to achieve the aims of improving the culture temperature and the fermentation temperature of the microorganisms. The culture medium can improve the high temperature resistance of the microorganisms in industrial production, and can play an important role in various industrial productions such as alcohol industry, fermented food industry, amino acid and nucleotide fermentation industry, organic acid fermentation industry, microbial transformation of organic compounds, industrial petroleum fermentation industry, energy development and the like.

Description

technical field [0001] The invention belongs to the field of industrial application of microorganisms, in particular to a culture medium for increasing the cultivation temperature of industrial microorganisms by using carbon nanomaterials and a preparation method thereof. Background technique [0002] The fermentation industry is a production centered on the cultivation and fermentation of microorganisms, and the temperature of microbial growth and reproduction is the basis of fermentation reactions. For example: During alcoholic fermentation, yeasts efficiently convert glucose into ethanol and carbon dioxide via the glycolytic pathway. However, one of the important problems in this route is that the most suitable temperature for enzymolysis of cellulose is between 45 and 50°C, while the optimum fermentation temperature for yeast is generally between 28 and 35°C, which makes the fermentation of yeast and fiber Therefore, improving the optimum fermentation temperature of eth...
