Match the microbial growth characteristics in column I with the corresponding features in column II.

Column I                                                                                        Column II

A. Growth associated product formation.                  1. Specific growth rate decreases with increasing product concentration.

B. Growth associated product formation                    2. Specific product formation rate is constant

C. Product inhibition                                                        3. Specific product formation rate is proportional to Specific growth rate.

D. Substrate inhibition                                                     4. Specific growth rate decreases with increasing substrate concentration.
