Abstract
Plastic pollution endangers ecosystems and human health globally, with High-density polyethylene (HDPE) as a major contributor. This study investigated the biodegradation using microorganisms of HDPE through a microbial process. Through a comprehensive literature review, Micrococcus luteus and Proteus vulgaris were identified as potential HDPE-degrading species and were selected for evaluation. Both strains exhibited growth using HDPE as the sole carbon source. By day 4, M. luteus achieved a cell density of 6.0 x 108 cells while P. vulgaris reached approximately 9.0 x 108 cells, indicating potential plastic degradation capacity. Results showed that P. vulgaris had the highest average weight loss at 3.33 ± 2.89, while M. luteus had an average of 1.38% ± 6.04. The consortium consisting of M. luteus and P. vulgaris exhibited lower weight loss averages, suggesting that degradation is more effective in individual cultures. However, the differences in the plastic degradation experiment were found statistically insignificant. A Scanning Electron Microscopy (SEM) analysis revealed that the surfaces of M. luteus and P. vulgaris showed unevenness, and pits, in contrast to the negative control. P. vulgaris possesses enzymes involved in plastic degradation such as catalase-peroxidase and lipase, while M. luteus possesses laccase. Both species degraded HDPE, with P. vulgaris having relatively higher efficiency in both carbon utilization and weight reduction. Future research should optimize growth conditions to enhance bacterial and enzymatic activity.
