Abstract

The invention relates to a method for fermenting and producing acrylic acid by Saccharomyces cerevisiae. Glycerol is used as a raw material, Saccharomyces cerevisiae is used as a host bacterium, and the method is catalyzed by several enzymes in the host bacterium. Beneficial effects of the present invention: 1) low-cost compounds are used as raw materials, and the raw material cost of the process is low. 2) Based on the technology of transforming microorganisms, the catalytic synthesis of biological enzymes is carried out in microorganisms, avoiding large-scale extraction, separation and purification processes, and easy to control in terms of production costs and environmental friendliness. 3) This process is less than other methods in terms of scale and quantity of production equipment, simple operation, and easy industrial transformation. 4) This process only has a separation and purification process in the final step of production. The product purification process is simple, and the product quality is better than the general method with better purity and higher content. 5) There is no waste liquid discharge in the synthesis process, which is environmentally friendly, pollution-free, and sustainable production.

Description

technical field [0001] The invention relates to a biosynthesis method of acrylic acid, in particular to a method for producing acrylic acid by fermentation of Saccharomyces cerevisiae. Background technique [0002] Molecular formula of acrylic acid: C 3 h 4 o 2 ; English name: Acrylic acid; CAS: 79-10-7; The temperature is 141°C, the flash point is 54°C, and the density is 1.05g / cm. [0003] Acrylic acid is an important organic synthetic raw material and synthetic resin monomer, and is a vinyl monomer with a very fast polymerization rate. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxyl group. Pure acrylic acid is a clear, colorless liquid with a characteristic pungent odour. It is miscible with water, alcohol, ether and chloroform. Most of them are used to make acrylates such as methyl acrylate, ethyl ester, butyl ester, and hydroxyethyl ester. Acrylic acid and acrylate can be homopolymerized and copolymerized, and its polym...
