- Plastics constitute an important part of our life for many decades. All the wastes produced from human activities finally enters into the aquatic ecosystem. Microbial degradation of plastic is a promising eco-friendly strategy which represents a great opportunity to manage waste plastic materials with minimum adverse impacts. In this present study, totally 248 bacterial isolates were isolated from the plastic waste dumped sites in the coastal region districts of Tamil Nadu, India and screened for HDPE degradation. Based on the results obtained from the weight loss, viability and FT-IR, 10 bacterial isolates were considered to be potent HDPE degraders. The identification of efficient HDPE degrading isolates confirms that most of the bacterial isolates belong to the genus Bacillus spp. and Pseudomonas spp. The present study suggests that the isolated efficient bacterial strains can be used as cost-effective, eco-friendly and safe approach for the elimination of plastic wastes from the environment.
