What is identified through the technique of replica plating?

Question

Quizplus · Accepted Answer

Replica plating is a technique used to identify auxotrophic bacteria. Auxotrophic bacteria are unable to synthesize certain nutrients required for growth and therefore, cannot grow on minimal media. Replica plating involves transferring bacterial colonies from one plate to another to determine if they can grow on minimal media. If a colony does not grow on minimal media, it is auxotrophic.
