FERMENTATION TECHNOLOGY

Fermentation is a complex process that involves molecular oxidation or reduction mechanisms driven by selective microorganisms under anaerobic conditions. This transformative process results in the production of various bioactive molecules, which offer significant health benefits. The fundamental principle of fermentation technology entails cultivating organisms under ideal conditions, providing them with essential raw materials like carbon, nitrogen, salts, trace elements, and vitamins. The primary function of fermentation lies in the conversion of NADH back into the coenzyme NAD+, allowing it to be utilized again in glycolysis. During fermentation, an organic electron acceptor (e.g., pyruvate or acetaldehyde) interacts with NADH to produce NAD+, yielding by products such as carbon dioxide and ethanol (as seen in ethanol fermentation) or lactate (in lactic acid fermentation). The metabolically derived end products, formed over the life span of microorganisms, are released into the surrounding medium. These products are then extracted for various human applications, holding significant commercial value. Based on the specific end product generated, fermentation can be categorized into four types: lactic acid fermentation, alcohol fermentation, acetic acid fermentation, and butyric acid fermentation. To facilitate the fermentation process, a fermenter or bioreactor is employed. This device is designed for the cultivation of microorganisms and contains all the necessary components for the large-scale synthesis of various compounds, including antibiotics, enzymes, and beverages across different industries. The microorganisms within the fermented are cultivated in a manner that maximizes the yield of the product while minimizing the required resources.
