Question

Fed-batch culture is not used for substrate inhibition.

(a) True

(b) False

The question was asked in an international level competition.

Question is taken from Fed Batch Culture topic in division Microbial Growth Kinetics of Bioprocess Engineering

Answer 1

The correct option is (b) False

Best explanation: Nutrients such as methanol, ethanol, acetic acid, and aromatic compounds inhibit the growth of microorganisms even at relatively low concentrations. By adding such substrates properly lag-time can be shortened and the inhibition of the cell growth markedly reduced.
