Bioreactors for Micropropagation, and for Bioactive Compounds
In order to reduce the cost of plant tissue culture either for micropropagation or for production of bioactive compounds automatic systems having bioreactors and bioprocessors are being developed. The Production rate can be enhanced tens of thousand times, so that now elite plants are being either multiplied or used for the production of bioactive compounds by plant biotechnology companies at the commercial scale. This has become necessary, particularly in the developed countries, where the major part of the operational cost is due to labour.

In India also, at BARC, airlift bioreactors of 20 litre capacity have been fabricated and used for the production of several bioactive compounds. In bioreactors, instead of a semi-solid agar medium, liquid culture media are used, which are prepared and replaced regularly through automatic devices in many cases. The growth conditions are also maintained automatically. For micropropagation, the Organogenic or embryogenic tissue is multiplied in bioreactors and transferred to a bioprocessor where propagules of different sizes are separated from each other. These propagules then grow and develop into plantlets in separate culture vessels, to be transplanted, stored or shipped.
