Q. Consider the following statements I. Bioreactors are vessels of large volumes in which raw materials are biologically converted into specific products II. One of the most commonly used bioreactors is of stirring type III. Shake flasks are used for growing and mixing the desired materials on a small scale in the laboratory IV. A large scale production of desired biotechnological product is done by using ‘bioreactors’
A) I and II
B) I and III
C) I, II and III
D) I, II, III and IV
Explanation
Small volume cultures are usually employed in laboratories for research and production of less quantities of products. e.g., in shake flasks. However, large scale production of the products is carried out in ‘bioreactor’ Bioreactors are large vessels (having a volume of 100 to 1000 L) which are used for biological conversion of raw materials into specific products. The most commonly used bioreactors are of stirring type
