Question

When C. glutamicum was grown in a medium containing a high concentration of biotin, the amount of glutamate produced was ________

(a) 10-40 µg/mg^-1

(b) 20-35 µg/mg^-1

(c) 25-36 µg/mg^-1

(d) 35-40 µg/mg^-1

This question was posed to me in an international level competition.

I would like to ask this question from Improvement of Industrial Microorganisms in chapter The Isolation, Preservation and Improvement of Industrial Microorganisms of Fermentation Technology

Answer 1

The correct choice is (c) 25-36 µg/mg^-1

The best explanation: When C. glutamicum was grown in a medium containing a high concentration of biotin, the amount of glutamate produced was 25-36 µg/mg^-1. When the proper amount of biotin is used, about 50 µg/mg^-1 of glutamate is produced.
