Scientists use gene editing to make beer taste more powerful

Scientists at the University of California, Berkeley, used gene-editing techniques to brew beer, and taste tests found that the special beer, which doesn't use hops, is more powerful than a beer made from hops, the Daily Mail of London reportedto achieve this , the researchers genetically modified the yeast strain and used it in brewing, successfully simulating the taste of hopsCharles Denby,, said in a paper that the brewing process uses hops with a lot of resources - a lot of water, fertilizer and energyOne pint (1 pint or 0.47 litres) requires up to 50 pints of waterAnd hops are expensivewants to use the technology it develops to brew premium beer in a more sustainable production processresearch team used CRISPR technology to create new yeast strainsCRISPR-Cas9 is a relatively low-cost gene editing tool invented by the University of California, BerkeleyDenby and partner Rachel Li inserted four different genes and gene-regulating promoters into industrial beer yeasttwo of these genes (aphoralyandase and fennel-alcohol-to-leaf enzyme) are the genetic code for certain enzymes that produce the scents that many plants haveThe researchers took the genes of mint and basilGenes in other plants, such as olives and strawberries, are active in camposeol-co-enzyme and are not easily processedthe remaining two genes come from yeast and promote the production of certain moleculesThe brewing process requires these molecules to produce fennel and fennel, which are the components of hopsresearchers put the yeast, basil and mint genes, promoters and Cas9 genes into the yeast together with tiny, round DNA plasmidsnext, yeast cells convert the Cas9 gene into Cas9 proteins that cut yeast DNA in certain locations after that, the enzyme that repairs yeast combines four new genes with promoters "The researchers used specially designed software programs to obtain the right hybrid starters to produce fennel and fennel alcohol, and they are similar in proportion to the proportion of commercial beer produced by Sierra Nevada Brewing Company," explains the report " Source: NetEase Technologies
