Biodegradation of low density polythene (LDPE) by pseudomonas species

Low density polythene (LDPE) is the most widely used packaging material primarily because of its excellent mechanical properties, barrier properties against water, light weight, low cost and high energy effectiveness. However, due to its ubiquitous nature, and resistance to biodegradability, the dis...
