Microbial Methane Fermentation Kinetics for Toxicant Exposure.

Abstract

Methane fermentation of industrial wastes offers the dual potential of pollution abatement and energy conservation. This report presents results of experiments designed to investigate the effects of toxic substances on methane bacteria. Toxicants studied were calcium, cadmium, chromium, nickel, sulfide, chloroform, dichloroethylene, trichloroethylene, ethyl benzene, cationic surfactants, gasoline, jet fuel, and hydrazine. The effect of toxicant concentration, solids retention time, and temperature on methanogenic response, acclimation, and reversibility was studied. Experiments included slug and continuous addition of toxicants.
