The Biology and Community Structure of CO₂-Reducing Acetogens in the Termite Hindgut
In the guts of wood-feeding termites, CO₂-reductive acetogenesis serves as the dominant sink for H₂ generated during the fermentation of wood polysaccharides. This activity can generate up to 1/3 of the acetate that powers the energy metabolism of the host insect. The gene for formyl-tetrahydrofola...
