Morphologies of LDPE film under the optical microscope. For morphological analysis, all LDPE specimens were taken after 30-day incubation except for blank (fresh film). Surfaces (a–d) and edges (e–h) were analyzed separately. a, e Blank group, indicating fresh LDPE film; b, f negative control, indicating LDPE specimens incubated in a flask in which bacterial cells were not inoculated; c, g LDPE film incubated with B. subtilis; and d, h LDPE film incubated with B. licheniformis
