Chapter 18, Problem 1TQ

Summary Introduction

To review:

The metabolic diversity of Proteobacteria and the use of different molecules to yield energy.

Introduction:

Proteobacteria is a Gram-negative bacterium. Lipopolysaccharide, receptor proteins, and porins in the outer membrane consist of two-thirds of the mass of the membrane. The shape of this class of bacteria can be spiral, cocci or rod. They display a diverse form and metabolism that includes phototrophy and heterotrophy on diverse organic substrates.
