Archaeal population on supporting material in methanogenic packed-bed reactor
The population of methanogenic archaea in a packed-bed reactor was determined. A difference between populations on the supporting material and in effluent was observed at operation under a high organic loading rate and a short hydraulic retention time. This difference was characterized by the predominance of Methanosarcina sp. on the supporting material.
