  • BGOrganic matter and sediment properties determine in

    Several studies have shown that in anoxic wetland and marine sediments rich in labile organic compounds the acetoclastic pathway dominates. With increasing recalcitrance the hydrogenotrophic pathway becomes more important as acetate being the direct precursor of CH 4 is depleted (Schoell 1988 Hornibrook et al. 1997 Miyajima et al. 1997).As suggested by Lojen et al.
