酶是蛋白质，起催化剂的作用。酶降低了反应发生所需的能量，而不会在反应中被消耗掉。许多类型的工业，以帮助生产他们的产品，利用酶。这些产品的例子有;奶酪，酒和面包。发酵是一种产生工业用酶的方法。发酵涉及使用微生物，如细菌和酵母来产生酶。有两种发酵方法用于生产酶。这两种发酵方式分别是浸入式发酵和固态发酵。浸没发酵是指微生物在液体营养介质中产生酶。 Solid-state fermentation is the cultivation of microorganisms, and hence enzymes on a solid substrate. Carbon containing compounds in or on the substrate are broken down by the microorganisms, which produce the enzymes either intracellular or extracellular. The enzymes are recovered by methods such as centrifugation, for extracellularly produced enzymes and lysing of cells for intracellular enzymes. Many industries are dependent on enzymes for the production of their goods. Industries that use enzymes generated by fermentation are the brewing, wine making, baking and cheese making.
