Synergistic effect of bacterial consortium on the biodegradation of nitroglycerin in aqueous medium through laboratory-scale bioreactor process

Abstract Nitroglycerin (NG) degrading bacterial strains were isolated from the soil samples obtained from contaminated regions of Salem and Sivakasi, Tamil Nadu, India. The isolated strains were tested for their ability to degrade of nitroglycerin in mineral salts medium at optimum temperature. Among 75 strains isolated, three strains were revealed more potent on the degradation of nitroglycerin. They were selected based on their efficiency in the breakdown of nitrogen molecules, the tolerant ability of glycerin and antagonistic assay. The selected strains were identified as Bacillus sp. and Pseudomonas sp. The mineral salts medium amended with NG was used to find out the optimum carbon source, pH and temperature for the degradation of NG. The rate NG degradation was found to be higher by using 1% glucose, pH 7.0 and 30 °C as the appropriate factors. Treated water from the bioreactor study was characterized using UV-Vis spectrophotometer, FTIR, HPLC and GC/MS analysis, which showed a potential degradation of NG by the bacterial consortium. Phyto-toxicity tests revealed that significant growth of green gram in the pots irrigated with treated water.
