Biocatalysis

Definition

Biocatalysis is the process of using natural catalysts, typically enzymes, to perform chemical reactions efficiently and selectively. This process is significant in industrial biotechnology and synthetic genomics, where it enables the transformation of raw materials into valuable products with reduced environmental impact and improved sustainability. By harnessing the power of biocatalysts, industries can achieve higher reaction rates, lower energy requirements, and minimized by-products compared to traditional chemical methods.
