| Abstract | Diesel is a mixture of alkanes and aromatic compounds frequently used as engine fuel. The spillage of diesel due to accidents during transportation, leakage from storage tanks and human activities leads to contamination of soil, sea water and fresh water. Components of diesel are toxic for the environment and carcinogen for human. Bioremediation is one of the environmentally friendly and high efficient method for remediation of diesel, wherein microbial activity has been used for this purpose. Immobilization of microbial cell is the optimal bioremediation technology because this method protects microbial cells from toxic and harsh environment condition as well as enhances microbial stability and easy to separate from the environment. In the present study, bacterial consortium TS1, isolated from water hyacinth roots, could degrade 1% diesel for 73.41% within 7 days. TS1 consortium was immobilized on fired clay pellets by adsorption method. Scanning electron microscope (SEM) revealed bacterial cells attached on the surface of fired clay pellet. The immobilized cells could efficiently degrade 1% diesel for 89.56% within 7 days. The immobilization of TS1 could also enhanced the biodegradation of diesel at higher concentration, in which 3% and 5% diesel were degraded for 80.83% and 70.90%, respectively within 7 days, which were higher than those of non-immobilized cell. |
