Hydrogen-Generating Reactions in Syntrophus and Syntrophomonas Have $$\Delta$$ G°' > 0 Can These Organisms Obtain Energy from Hydrogen Formation?
A)

Hydrogen-generating reactions in Syntrophus and Syntrophomonas have $$\Delta$$ G°' > 0. Can these organisms obtain energy from hydrogen formation?

A) No, they cannot.
B) No-they produce energy by breaking down molecules such as benzoate or butyrate.
C) Yes-hydrogen-producing microorganisms coexist in syntrophy with H₂-consuming bacteria. Utilization of H₂ ( $$\Delta$$ G°' < 0) drives the process forward.
D) Yes, but only when oxygen is present.
E) Yes-this happens in sewage but never in a laboratory setting.
