Summary Introduction

To answer:

The nutritional classification of Desulforudis audaxviator. This bacterium lives underground, its energy source is sulfate, obtains electrons from hydrogen and builds the organic molecules by using the inorganic molecules seen in the nearby rocks.

Introduction:

All the bacteria require carbon source and energy source for their growth and development. Depending on the carbon and energy requirement, the bacteria can be classified into four categories, namely photoheterotrophs, photoautotrophs, chemoautotrophs, and chemoheterotrophs.

The microorganisms that utilize inorganic molecules as electron donors are known as lithotrophs. The microorganisms that use organic compounds as electron donors are known as organotrophs.
