The goal of our work and contribute to the production of biogas through anaerobic digestion, is to be used as raw
material mud from the sewage wastewater from the city of Touggourt. The sample is allowed to ferment in a
digester in anaerobic conditions during 14 days. Biogas production closely follows the phase reported in the
literature. Indeed, the change in pH due to volatile fatty acids, for the raw sludge sample, enabled us to determine
the duration of each phase. To carry out our work we have carried out a preliminary study on the one hand, physicalchemical
and microbiological characteristics, and finally we measured the ability of microorganisms to degrade
