Rumen Fermentation Butyrivibrio fibrisolvens Common cellulolytic bacteria. Ferments hexoses and pentoses to acetate, butyrate and hydrogen. The production of butyrate is used to regenerate NADP which is used in the conversion of glucose to pentoses and to regenerate the NAD used in the Embden-Meyerhof pathway into which pentoses are funnelled. The production of acetate serves as a pathway for ATP generation.

Rumen Fermentation Butyrivibrio fibrisolvens Hexoses and pentoses are converted to pyruvate through multiple steps with the generation of ATP, regeneration of NAD and the production of hydrogen. Pyruvate is then converted to acetyl CoA with further regeneration of NAD and production of hydrogen.
