The current article investigates the biodegradation ability of Brevibacillus, Pseudomonas, and Rhodococcus spp. in degrading polyethylene. Shake-flask incubation for 3 weeks was performed for the purpose of biodegradation. The initial and final dry weights of polyethylene before and after incubation in the culture medium were compared and the percentage of degradation was calculated. Pseudomonas was found most efficient in degrading polyethylene with its biodegradability of 40.5% followed by Brevibacillus with 37.5% and Rhodococcus with 33% biodegradability, respectively.
