| description | - Synthetic polymers like polyethylene terephthalate (PET) and high density polyethylene (HDPE) are hazardous
pollutants for the environment. The aim of this study is to investigate the ability of microbes in soil and water samples from
three different waste dumping sites in Chittagong to degrade PET and HDPE pellets. The sites are: sewage drain next to the
Asian University for Women (AUW) campus, the landfill of Chittagong City Corporation (CCC) in Anandabazar, and the
ship breaking yard in Sitakunda. Nineteen selected microbes from these samples were cultured on nutrient agar at 37oC and
their ability to biodegrade PET and HDPE were tested by placing the weighed pellets on the cultured agar plates. These
plates were observed periodically for about a month and final weights of the pellets were recorded. Similarly, the experiment
was also carried out in nutrient broth with sixteen microbes. Results from the agar method showed mean percent weight loss
of 8.32±0.52 in PET pellets by L3AW1 sample and 7.10±2.83 in HDPE pellets by L3AW3 sample. In the broth method,
percent weight loss was observed 11.77 in PET by L3AW3 and 5.26 in HDPE by S4SB1 sample. Identification of microbial
strains based on morphology and biochemical tests were conducted using Bergey’s Manual of Bacteriology. Further studies
will be conducted for accurate identification of the microbial strains, enzymes involved in degradation and assessment on
feasibility of commercialization of desired enzymes. |
