Detailed explanation-1: -Fermentation is a process that helps break down large organic molecules via the action of microorganisms into simpler ones. For example, yeast enzymes convert sugars and starches into alcohol, while proteins are converted to peptides/amino acids.
Detailed explanation-2: -Highlights. Fungi have an important role in food fermentation since ancient times. Alcoholic beverages, breads, cocoa, and so on, depend on yeasts fermentation. Molds are involved on production of moldy ripened cheeses and sausages, sake, and shoyu.
Detailed explanation-3: -During fermentation, yeast cells convert cereal-derived sugars into ethanol and CO 2 . At the same time, hundreds of secondary metabolites that influence the aroma and taste of beer are produced. Variation in these metabolites across different yeast strains is what allows yeast to so uniquely influence beer flavor [9].
Detailed explanation-4: -In the fermentation process, the mold secretes enzymes for saccharification and liquefaction while the yeast is fermented. In brewing, the mold provides abundant enzymes and becomes an essential brewing microorganism.
