What is Fermentation? Fermentation is the proce ss in which the chemical transformation of organic substances into simpler compounds carried out by the action of bio-catalysts (enzymes) produced by microorganisms like bacteria, molds or yeasts. The enzymes act by hydrolysis, a process of predigesting or breaking down of composite organic molecules into smaller units or more easily digestible stuffs in case of foods For example… The enzyme carbohydratases act on carbohydrates. For an instance, enzyme amylase act on starch and convert it them into simple sugars which can be utilized easily by the microorganisms The enzyme proteases act on various proteins. For an instance, enzyme protease breaks down huge protein molecules initially into polypeptides and peptides and then into numerous amino acids, which can be readily and easily taken up by the microorganisms The enzyme lipases on various lipids. For an instance, the en
