Question
Chapter 7, Problem 2.3SC
Summary Introduction
To describe: Does the fastidious microbes contain a lesser or greater number of enzyme types than micro-organisms having simple nutritional needs.
Introduction: Fastidious microbes are those that have special nutritional requirements for their growth and are difficult to grow in the laboratory. Some examples of fastidious microbes are Neisseria, Mycoplasma and Mycobacterium.
