The hydrolysis kinetics of the fish residues, which contained primarily proteins and lipids, were examined at initial ammonia concentrations of 0-16 g N l-1. Carbon hydrolysis was suppressed more by ammonium in the acidogenesis phase than in the acidogenesis/methanogenesis period of a single-stage anaerobic digestion. Conversely, hydrolysis of compounds containing nitrogen was similarly suppressed by ammonia during acidogenesis and acidogenesis/methanogenesis phases of a single-stage anaerobic digestion. Parameter uncertainty analysis demonstrated that the proteins fraction in the fish residues was entirely biodegradable. Model fitting demonstrated that two fractions of lipid substrates exist, namely, easy and hard to biodegrade with hydrolysis rates that were affected differently by ammonia content. ? 2007 Springer-Verlag. |
