Industrial Biotechnology Lecture 3 Quiz

To promote the emergence of beneficial mutations and adaptive traits in bacterial populations through prolonged cultivation under selective pressure.

Bacterial populations are grown under controlled conditions with continuous exposure to selective pressures, and cultures are periodically transferred to fresh media to maintain exponential growth and allow for the accumulation of adaptive mutations.

Evolved populations are screened for desired phenotypic traits, such as increased growth rate, substrate utilization, or stress tolerance.
