Question

Give reasons for the following:

(a) Most media that are used for culturing microbes in laboratories are not used for large scale cultivation.

(b) Aeration is important for microbial growth.

(c) Foaming caused during fermentation process can be harmful to the process.

Answer 1

(a) Lab media contain highly purified and costly chemical constituents which can’t be economically used for large scale production.

(b) Provides uniform mixing of the medium and avoids development of anaerobic pockets thus ensuring optimum oxygen availability for growth.

(c) Foaming denatures the proteins so it is undesirable.
