Abstract:
The use of plastic bags made from low density polyethylene (LDPE) is one of the main
sources of environmental pollution, because it degrades very slowly in nature so that it
accumulates in large quantities in the environment. Biodegradation is an important
approach to waste reduction that relies on biological processes to break down plastic
pollutants. This study screened fifteen Riau local fungi isolates for their ability to degrade
Low-density polyethylene (LDPE) plastic. Fungi capable of degrading this polymer showed
the presence of fungal growth on selective media, namely MSA with the addition of 0.1%
w-/-v LDPE powder. The results showed that all isolates could grow on the medium with
the largest growth diameter found in Aspergilllus fumigatus KP (8,13 cm) and the smallest
in Penicillium PN4 (1,22 cm) within 3 days of incubation
