MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA (microbiological testing media C12Q1/00)

Description

C12N covers microorganisms, enzymes, and their compositions, including methods for propagation, preservation, and maintenance of microbial cultures. It encompasses genetic engineering and mutation techniques applied to microorganisms, as well as the formulation and preparation of culture media required for microbial growth. This subclass serves biotechnology and industrial microbiology applications ranging from pharmaceutical production to fermentation processes, but excludes downstream applications of microbial products (handled in other C12 divisions) and general chemistry of enzymes outside a microbiological context.
