A medium containing a vitamin is to be sterilized. Assume that the number of spores initially
present is
The values of the pre-Arrhenius constant and 
for the spores are 
For the inactivation of the vitamin, the values of 
are 
The initial concentration of the vitamin is 30 mg/l. Compare the amount of active vitamin in
the sterilized medium for 10-l and 10,000-l fermenters when both are sterilized at 121∞C
when we require in both cases that the probability of an unsuccessful fermentation be 0.001.
Ignore the effects of the heat-up and cool-down periods.
