SKRINING JAMUR PENDEGRADASI PLASTIK LOW DENSITY POLYETHYLENE (LDPE)

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
