FERMENTATION OR ENZYME-USING PROCESSES TO SYNTHESISE A DESIRED CHEMICAL COMPOUND OR COMPOSITION OR TO SEPARATE OPTICAL ISOMERS FROM A RACEMIC MIXTURE

Introduced: January 1980

Classification Context

Section:: CHEMISTRY; METALLURGY
Class:: BIOCHEMISTRY; BEER; SPIRITS; WINE; VINEGAR; MICROBIOLOGY; ENZYMOLOGY; MUTATION OR GENETIC ENGINEERING
Subclass:: FERMENTATION OR ENZYME-USING PROCESSES TO SYNTHESISE A DESIRED CHEMICAL COMPOUND OR COMPOSITION OR TO SEPARATE OPTICAL ISOMERS FROM A RACEMIC MIXTURE

Description

C12P covers biotechnological and enzymatic synthesis processes used to produce desired chemical compounds, compositions, or to resolve racemic mixtures into optically pure isomers. This subclass encompasses fermentation-based chemical manufacturing, enzyme-catalyzed reactions for organic synthesis, and bioconversion processes across pharmaceuticals, fine chemicals, and industrial compounds. It includes microbial fermentation for metabolite production, recombinant enzyme applications, and biocatalytic transformations, but excludes processes primarily directed at beverage production (beer, wine, spirits, vinegar) which are covered separately within C12. Related processes involving genetic modification of organisms for enhanced bioproduction fall within C12N.

Glossary

Microorganism microorganisms comprises single-celled organisms such as bacteria, actinomycetales or single-celled fungi, e.g. yeasts; for the purposes of classification, this term also includes viruses, human, animal or plant cells, protozoa, tissues and unicellular algae.
