Industrial biotransformation involves the use of biological systems, such as microorganisms or enzymes, to convert raw materials into valuable products. It is widely applied in the pharmaceutical, food, and chemical industries. This process allows for specific, efficient, and eco-friendly transformations under mild conditions. Biotransformation can modify complex molecules that are difficult to synthesize chemically. Enzymes used in these processes offer high selectivity and reduce unwanted by-products. Common examples include the production of antibiotics, steroids, and biofuels. Industrial biotransformation enhances sustainability by using renewable substrates. It represents a key tool in modern industrial biotechnology for producing high-value compounds.
