Question 1
In batch fermentation, a lag phase can be minimized by:
using a highly active inoculum
adding less biomass in the inoculum
adding less substrate to the medium
changing the carbon source between the inoculum and the medium
Question 2
For enzymes immobilized on a solid support, a Damkohler number >>1 indicates the reaction is diffusion limited.
True
False
Question 3
If the Thiele modulus is very small, the substrate does not reach the core of a porous catalyst particle.
True
False
Question 4
The growth yield is constant during batch growth
True
False
Question 5
For uncompetitive enzyme inhibition:
the apparent Km increases (compared to the uninhibited enzyme)
the apparent Vmax increases (compared to the uninhibited enzyme)
the apparent Km decreases (compared to the uninhibited enzyme)
the apparent Vmax decreases (compared to the uninhibited enzyme)
