This study used the experimental research design. The isolation of bacteria and collection of used polystyrene took place in a landfill located in Cabuyao, Laguna. Furthermore, the experimentation, which includes inoculation and incubation of the bacterial isolate, took place in a research laboratory in Dasmarinas, Cavite. Lastly, the use of scanning electron microscopy for the analysis of the samples was done in the Nanotech Analytical Services and Training Corporation (NASAT Labs). The study concluded that the use of bacterial isolates namely, K. pneumoniae, P. mirabilis, E. coli, P. aeruginosa, S. enterica and E. cloacae exhibited effective as biodegrading capabilities for expanded polystyrene beads.
