Hormone microbial, table

Biopharmaceuticals that are industrially produced by microbial (bacterial or yeast) fermentation include insulin, human growth hormone, hepatitis B surface antigen vaccine, alpha interferon, beta interferon, gamma interferon, granulocyte colony stimulating factor, and interleukin-2. Table 30.8 lists some of the major biopharma products, some of which are produced by mammalian cell culture. 

The ionophores and several other specialty products are included in Table 13.8 for comparison purposes. Products of mammalian cell culture such as plasminogen activator and erythropoietin are included as fermentation products in this listing because they are normally manufactured by cellular processes in bioreactors. Aside from the five commodity chemicals in this table, the most dramatic change in the commercial chemicals produced by fermentation results from the impact of genetic engineering and recombinant DNA methods on the specialty products. Antibiotics and biopolymers (hormones, enzymes, etc.) with molecular structures too complex for conventional chemical synthesis will continue to be manufactured by microbial processes (Hinman, 1993).
