Abstract

One of the most often utilized polymers, low density polyethylene (LDPE), has contaminated the environment. Plastic use has increased over the past several decades due to its versatility. The majority of the methods for managing LDPE already in use was neither ecologically nor economically sounds. The issue brought about by LDPE wastes may be resolved via LDPE biodegradation. After being separated from the polluted soil, the bacterial strains were enhanced to increase their ability to break down LDPE. Molasses was added to the polluted soil after enhanced bacterial strains were introduced. At various trial times (0, 6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 hours), the effects of various amounts of contaminated soil, such as 0, 50, 200, 350, 500, and 650 mg, were assessed. According to the findings in treatment, bacterial growth (Staphylococcus and Bacillus species) and breakdown rates were greater at 350 mg concentrations of LDPE. As a result, the bacterial strains may be used to manage LDPE wastes without contaminating the environment through the biodegradation of LDPE.
