- Humulin - Human Insulin
- Bacterial cell (e.g. E Coli) has been transformed by the addition of recombinant DNA
- culture (large population) of the bacterial cell would be injected into the fermenter
- the fermenter must provide the culture with nutrients, control of temperature, pH and the gases inside the fermenter
- by creating the optimal temperature for bacterial growth - you will see the population increase
- the Bacteria switches on the gene for insulin and manufactures the protein Insulin from the provided Amino acids (in the nutrients)
- then the product must be removed for purification - downstream processing (for human use)
- the genetically engineered human insulin is called Humulin
