What are bioreactors?

Explanation

Bioreactor used in biotechnology is generally used to process 100-1000 litre of material. It has a cylindrical metal container with a curved base to facilitate mixing of contents. The culture medium containing all the nutrients, salts, vitamins, hormones, etc. is added alongwith inoculum of transformed cells with recombinant DNA. A stirrer helps in mixing and optimum availability of nutrients to culture cells. Supply of oxygen is maintained if the cells function better under aerobic .conditions. Foam is kept under control. Gadgets are attached for knowing temperature and pH of the contents. Corrections are made when required. There is a sampling port where small volume of culture can be withdrawn to know the growth of cells and concentration of extractable product.
