Microorganisms play an indispensable role in industrial biotechnology through their involvement in fermentation and product formation. Fermentation is fundamental in producing various foods and beverages, including bread, yogurt, beer, and wine, and it also plays a crucial role in the pharmaceutical and biofuel industries. Microorganisms such as Bacillus subtilis and Sacchoromyces cerevisiae are widely used for the efficient production of high-value biomolecules such as amylases, proteases, cellulases, and lipases, which are widely used in the food, pharmaceutical, and biofuel industries. The commercial application of microbial metabolites has significantly influenced the health, agriculture, and food processing sectors. Fermentation-derived products such as ethanol, lactic acid, acetic acid, citric acid, carbon dioxide, and hydrogen gas, various organic compounds, depending on the type of fermentation, and microorganisms involved are widely utilized. These products are integral to numerous industries, serving roles in food and beverage production, pharmaceuticals, and biofuel manufacturing. Antibiotics as microbial-derived products have been instrumental in combating infections. Beyond antibiotics, microbial metabolites also play a role in therapeutics, which has been an emerging area in biotechnological advancements.
