Kinetics of pyridine degradation along with toluene and methylene chloride with Bacillus sp. in packed bed reactor

Abstract

Bacillus coagulans strain isolated from contaminated soil was immobilised on activated carbon for degradation of pyridine, toluene and methylene chloride containing synthetic wastewaters. Pyridine was supplied as the only source of nitrogen in the wastewaters. Continuous runs in a packed bed laboratory reactor showed that immobilized B. coagulans can degrade pyridine along with other organics rapidly and the effluent ammonia is also controlled in presence of “organic carbon”. About 644 mg/l of influent TOC was efficiently degraded (82.85%) at 64.05 mg/l/hr loading.
