Dear Horst!
(1) Methanogens are neither bacteria nor archaea bacteria. Methanogens
are archaea. Bacteria and archaea are two distinct taxonomic domains.
(2) Interspecies hydrogen transfer (IHT) does not primarily affect the
redox potential but the concentration of hydrogen in solution.
(3) IHT depends on the interaction of two groups of microorganisms, viz.
methanogens and acetogens. The latter group has to be distinguished from
the acidogenic bacteria.
Best regards,
Holger.
