Question
Chapter 10, Problem 6RQ
Summary Introduction
To review:
The impact of glucose on the utilization of lactose as a carbon source.
Introduction:
All forms of microbes need nutrients to produce energy and this includes carbon, nitrogen, phosphorus, and other molecules as essential nutrients. The carbon source is mainly used to promote the growth of cells and for product formation. Carbohydrates are used as a major source of energy by both anaerobes and aerobes to produce energy through different processes.
