Methanogenic, Acidogenic and Hydrolytic activity tests of an anaerobic sludge of municipal wastewater plant

The determination of methanogenic and non-methanogenic activity requires careful analysis because don’t exist a standardized method to find this bioindicator. Therefore, we wanted to evaluate and optimize this analytical method for the characterization of anaerobic sludge. We did five experiments, w...
