Anarobic biodegradability for sulfolane and thiolane wasingvestigated in soil and anaerobically digested sludge. Biochemicalmethane potential was periodically quantified to assessbiodegradability of microorganisms degrading the compounds preparedin the closed glass vessel. Relatively lower concentration ofthiolane adopted in the test was hardly degraded in the soil.Moreover, its degradation was hindered in anaerobic digest sludge. Inconstrast, sulfolane was readily deocomposed in both the soil and theanaerobic sludge. It is concluded that subsequent occurrence hinderedin anaerobic digest sludge. In constrast, sulfolane was readilydecomposed in both the soil and the anaerobic sludge. It is concludedthat subsequent occurrence of thiolane as one of intermediatesgenerated from the reduction of sulfolane would reard the remediationof the concerned area polluted with sulfolane and thiolane.
