Hydrogen and acetate inhibit the microbial degradation of propionate and ethanol in digesting sludge. Propionate oxidation is more sensitive than ethanol oxidation to product activities. This difference can be explained on thermodynamic grounds. It is concluded that the limiting factors for complete anaerobic mineralization of biodegradable organic matter in digesting sludge are to be sought in the boundary conditions for the exergonic oxidation of propionate. The different ecological… CONTINUE READING
