Question

Describe briefly the bioreactors.

Answer 1

Hint: The artificial conditions set up to extract the foreign gene product on a wide scale are bioreactors. A foreign gene is expressed in the target protein in a heterologous host called recombinant protein with the assistance of recombinant DNA technology.

Complete answer:
A bioreactor refers to a mechanism (aerobic or anaerobic) where a biologically active ecosystem is supported by a device. It is a chemical process where a system is produced in a regulated manner for developing organisms such as yeast, bacteria, or animal cells. These bioreactors are also used for the creation of vaccines and antibodies in factories. Organisms are located in vessels in this chemical phase. They are cylindrical and have a stainless steel frame. The same kind of atmosphere is created by bioreactors and guarantees the same temperature, oxygen level, and pH level. The three steps are used in the method of extracting international gene products from bioreactors:
a. Upstream processing in which the raw material is an origin in which it is transformed into an appropriate form.
b. Bioreaction, where it is then transferred to another stage of bioreaction.
c. Production downstream, where the content is further refined into a more valuable by-product.
For example, the ecological conditions within the bioreactor affect the production and productivity of creatures grown in the bioreactor, temperature, complement fixation, pH, and disintegrated gases. A cooling coat, curls, or both, holds up the temperature of the aging medium.

Note: Bioreactors contain several systems for preserving optimum conditions. They are the agitator system, the oxygen distribution system, the foam control system, the temperature control system, the pH control system, the sampling ports for a limited amount of culture to be removed.
