BIOLOGICAL DEGRADATION OF LOW DENSITY POLYETHYLENE (LDPE)AFEEFA ATEEQ AND AMAR P. GARGAbstract Polythene is a serious problem which causes pollution to the environment and pollutes the land and marine ecosystem. However, the biological degradation could be a solution of polythene pollution. According to the previous studies microbes have ability to degrade polythene. Microbes use polythene as their carbon source and energy. In this present research, we found fungal strain which degrade polythene in 45 days. The isolated fungi have shown great ability to degrade and they grow rapidly and can be isolated from the soil. We isolate Aspergillus fumigatus and it has have ability to degrade the LDPE. Some enzymes such as Polyesterases, esterases, Lipases and hydrolases involved in degradation of polythene and produced by the Aspergillus fumigatus. The isolated fungi secrete Lipases enzyme showed activity on agar plate assay and halo area was measured as 4.67mm. So our study suggest that polythene can be degrade by microorganism and we can overcome from the white pollution from the natural process. |
