Yeast strain of beer and application thereof

Technical field: [0001] The invention belongs to the field of microbes, in particular to beer yeast strains and applications thereof. Background technique: [0002] Brewer's yeast is the soul of beer fermentation, and the work of breeding excellent strains is a process with a heavy workload and slow results. Although molecular biology technology is very developed today, it is not difficult to construct a beer yeast strain with a certain indicator by means of genetic engineering and other technical means, but based on consumers' safety considerations, and the complete deletion of a certain Genes or the introduction of foreign genes may destroy the metabolic balance in the yeast cells and affect the requirements of the index balance characteristics of the beer fermentation process. Therefore, so far, no beer company in the beer industry at home and abroad has declared that it uses genetically modified yeast strains to produce beer , the traditional (classical) mutation breedi...
