Abstract

The invention relates to a method for high-yielding short-chain fatty acids by utilizing microbial symbiotic fermentation technology. The present invention utilizes microbial symbiotic fermentation technology to produce high-yield short-chain fatty acids, takes Jerusalem artichoke and seaweed with high yield and easy acquisition as raw materials, that is, uses food-grade materials as fermentation substrates, and utilizes multi-bacteria symbiotic fermentation technology to produce short-chain fatty acids. Compared with the process of preparing short-chain fatty acids by using carbohydrate composition and pure cellulose in the technology, it overcomes the disadvantage of high cost of preparing short-chain fatty acids, and is simple to operate, safe and non-toxic, high in yield, easy to scale production, and has the advantages of The method has good economic benefits and wide application range, and provides new raw materials and new methods for preparing short-chain fatty acids.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a method for high-yielding short-chain fatty acids by utilizing microbial symbiotic fermentation technology. Background technique [0002] Short-chain fatty acids (SCFAs), also known as volatile fatty acids (Volatilefatty acids, VFA), are organic carboxylic acids with 1 to 6 carbon atoms, and are carbohydrates (oligosaccharides, oligosaccharides, After non-starch polysaccharides, resistant starch, etc.) enter the large intestine, the end products produced by bacterial fermentation mainly include acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid, and valeric acid, of which 90% to 95% The SCFAs are acetic acid, propionic acid, and butyric acid. [0003] Short-chain fatty acids are the fermentation products of intestinal microorganisms, and their effects on the health of the body have been widely studied: ①SCFAs can improve intestinal di...
