3. Termites
A. Spirochetes play a fundamental role when it comes to the nutrition of termites. They use acetate produced by microbes as a major source of energy and of Carbon. Spirochetes N2 fixation also plays an important role in the nitrogen economy of termites. The N2 fixation of these spirochetes is significant for a lot of different environments

B. Acetogenic spirochete:
-Spirochetes that have been previously cultured, posses the ability to conserve their energy by the oxidation of H2
-The reduction assay of acetylene assays for the cells’ nitrogenase activity

Termite:
-Oxidation of the Acetate produced by the hindgut microbes is one of the most important sources of energy and Carbon for termites. It supports 100% of the insects’ respiration requirements …show more content…
The capability of spirochetes to use Hydrogen as a reductant for acetogenesis helps by reconciling the mysterious domination of acetogenesis over methanogenesis as a Hydrogen sink in a lot of termites. The zone in which the most H is consumed is attributed to spirochetes, which progress amid protozoa in the anoxic central region.
Also termites are known to produce more carbon dioxide than all the fossil fuels burned all around the world multiplied by 10. Termites that have a large acetogenic population are less of a concern because hindgut microbes use both hydrogen and carbon dioxide to produce the Acetate that they need as an energy source and for their respiration
