(a) How has the development of bioreactor helped in biotechnology?
(b) Name the most commonly used bioreactor and describe its working

Explanation

(a) Bioreactores are used for processing large volume of culture ofro obtaining products of intereset in sufficent quantities bioreactor is a large vessel in which raw material is bilogically converted in to specific product under optimal condition .A bnioreactor prodived the optimal conditions for acheiing the desired proddut by providing optimum growh conditons such as temperatures pH substrates salts, vitamins ,oxygen
(b) simple stirred tank bioreactor: A stirred tank ractor is usually cylindrical or with a curved base to facilatee the mi9xing of the reactor contents and the stirrer facitlitates evben mixing and oxygen availiability throughout the biroeactor .
