Abstract

Thermophilic methane-producing bacteria isolated from a wastewater treatment facility have been immobilized in acetylcellulose filter with agar. The immobilized cells produced methane from wastewaters in rich organic acid (acetic, propionic and butyric acids) at the rate of 1.4 μmol mg protein-1 h-1. The optimum conditions for methane production by immobilized whole cells were 52-55°C and pH 7.0-8.0. The immobilized cells retained 80% of the initial activity after exposure to air. The immobilized thermophilic bacteria produced methane continuously over 10 days at 52°C.
