title: Microbial degradation of pyridine and alpha-picoline using a strain of the genera Pseudomonas and Nocardia sp.
abstract: Biodegradation of pyridine and alpha-picoline (2-methyl pyridine) by Pseudomonas pseudoalcaligenes-KPN and Nocardia sp. isolated from garden soil were investigated in batch culture experiments. Pyridine and alpha-picoline (50-200 mg L(-1)) were used as sole source of carbon and energy in the investigation. The kinetic constants were evaluated for pyridine and alpha-picoline degradation under optimized nutritional (C, N, P) and environmental (pH, temperature) conditions. The values of bio-kinetic constant obtained in the present investigation indicate the usefulness of both the cultures for treatment of waste containing pyridine and its derivatives.
