Fermentation culture medium for producing methanol protein

Abstract

The invention relates to a fermentation culture medium for producing methanol protein, and the fermentation culture medium can effectively solve the problems of low protein content, high salt content and no guarantee of product quality. The invention adopts the following technical scheme: the fermentation culture medium comprises the following components: 24.5-25.5 ml of phosphoric acid with the mass concentration of 85%, 0.85-0.88 g of calcium sulfate, 17-17.8 g of potassium sulfate, 15.5-16.08 g of magnesium sulfate, 3.5-4.0 g of potassium hydroxide, 42-44 g of glycerol, 3.5-3.8 ml of 1-phenyl-5-tetrazole-thione and 1,000 ml of water. The fermentation culture medium is scientific and reasonable in formula, has a good use effect, can effectively solve the problems of low protein content, high salt content and no guarantee of product quality, and is an innovation in methanol protein production.

Description

technical field [0001] The invention relates to biotechnology, in particular to a fermentation medium for producing methanol protein. Background technique [0002] The application of fermentation to produce single-cell protein as feed has many reports at home and abroad, and some processing techniques are relatively mature, such as Candida, Saccharomyces cerevisiae, etc. There are many reports of single-cell proteins. However, there are not many reports on the production of single cells using methanol as the main carbon source. At present, the methods for producing methanol protein at home and abroad mainly include bacterial fermentation and yeast fermentation. The bacterial method includes the ICI method in the UK. Germany's Hoechst-Uhde method and Sweden's Norprotein method: yeast strain production methods include the MGC method in Japan, the IFP method in France and the Philips Petroieum method in the United States (Zheng GH, 2002.
