Abstract
Due to COVID-19, the demand for alcohol products has increased a lot, mostly for disinfectants, but this has lead to the increase of the market price of such products, causing some people not able to afford disinfectants. One way we thought could solve this problem is to use the gene-editing method to edit the yeast when fermenting wheat starch, so it can accelerate the speed of the process when producing alcohol. We edit the genes of xylanase, β-xylosidase, and acetyl-xylan esterase into the yeast which could produce these enzymes themselves to further break down the non-starch polysaccharide in the wheat starch-B so that the yeast can use them directly to produce alcohol. Our solution presents a faster and lower-cost production mode which would lead to lower prices for customers and avoid food waste.
