What does biocatalysis mean?
Biocatalysis is the use of biological catalysts — most often enzymes, but sometimes whole cells — to accelerate or steer chemical reactions. Because enzymes are highly selective, biocatalysis can transform specific starting materials into desired products under mild conditions of temperature and pressure, producing less waste than many conventional chemical processes. This makes the term central to green chemistry and to industries such as pharmaceuticals, food processing, and biofuels, where it is prized for enabling reactions that are otherwise difficult, expensive, or environmentally harmful. The word is technical in register, appearing mainly in scientific literature, patents, and industry reporting rather than casual speech, and it typically carries favorable connotations of sustainability, efficiency, and precision. Related forms include 'biocatalyst' for the agent itself and 'biocatalytic' as the adjective. For anyone interested in how nature's chemistry is harnessed in modern manufacturing, biocatalysis is an essential concept to know.
nounThe use of natural catalysts — especially enzymes, but also whole cells or other biological molecules — to speed up chemical reactions.
- The use of enzymes or whole cells as catalysts to accelerate or direct chemical reactions, especially in industrial or laboratory synthesis.
"Modern pharmaceutical manufacturing increasingly relies on biocatalysis to produce single-enantiomer drugs efficiently."
"The company replaced a costly metal catalyst with biocatalysis, cutting both waste and production time."
"Advances in protein engineering have made biocatalysis a cornerstone of green chemistry."
The plural is rare and appears mostly in academic or patent literature when referring to multiple distinct biocatalytic reactions or processes.
"The review surveyed several biocatalyses developed for asymmetric synthesis over the past decade."
Your own body runs thousands of biocatalytic reactions every second — and chemists have spent decades learning to borrow those same enzymes to build medicines in the lab.

Etymology of biocatalysis
Biocatalysis is a compound of 'bio-', from Greek bios meaning 'life', and 'catalysis', from Greek katalysis meaning 'dissolution' or 'loosening', derived from katalyein, 'to dissolve'. The term catalysis was introduced into chemistry by Jöns Jacob Berzelius in the 1830s, and 'biocatalysis' emerged later as scientists recognized that enzymes and living cells act as natural catalysts. It shares its root with words such as 'catalyst', 'catalytic', 'analyze', and 'paralysis'.

How biocatalysis is actually used
Biocatalysis is a technical term used chiefly in chemistry, biochemistry, chemical engineering, and industry; it rarely appears in everyday conversation. It carries a positive connotation of sustainability and precision, often invoked in discussions of green chemistry. The plural 'biocatalyses' exists but is uncommon outside academic writing.
Easily confused with biocatalysis
Catalysis is the general speeding-up of a reaction by any catalyst, whereas biocatalysis specifically uses biological agents such as enzymes or cells.
Bioremediation uses microorganisms to break down pollutants in the environment, while biocatalysis is the use of enzymes or cells to drive chemical reactions, typically in industrial synthesis.
