Web14.5.2 Enzymes. Biocatalyst or enzymes are the class of biomolecule which selectively act on the substrates to give the desired products. The advantages of a biocatalyst over other catalysts is the high reaction rate, high specificity, biodegradability, nontoxicity, and reaction at mild environmental conditions (pH, temperature, and pressure). WebJan 1, 2024 · Microbial enzymes are also used as biocatalysts in various industrial processes in an economical and environmentally-friendly way, as compared with chemical catalysis. Over the past few decades, the use of microbial enzymes in bioprocesses has increased rapidly, because of their catalytic activity, as well as stability.
