Match the microbial growth characteristics in Group I with the corresponding features in Group II.
Group I
P. Growth associated product formation
Q. Non growth associated product formation
R. Product inhibition
S. Substrate inhibition
Group II
1. Specific growth rate decreases with increasing product concentration
2. Specific product formation rate is constant
3. Specific product formation rate is proportional to specific growth rate
4. Specific growth rate decreases with increasing substrate concentration

Correct Option: B
At growth associated product formation specific product formation rate is proportional to specific growth rate when Non growth associated product formation shows the constant sp. Growth rate. Product induced inhibition can be seen at increase in product concentration with decrease in sp growth rate, this phenomena is vice versa with substrate inhibition.
