Abstract: ANUAT, JESREENE M., VERGARA, SOHFIA JESSE N. AND VICEDO, RIA ROCEL D. Screening of Low Density Polyethylene (LDPE) Plastic Degrading Filamentous Fungi Isolated from Backyard Soils. Research Study (General Science Curriculum). Science High School, College of Education, Cavite State University. Indang, Cavite. April 2015. Adviser: Ms. Sherine M. Cruzate. The study was conducted to screen filamentous fungi isolated from backyard soils for its capability to biodegrade LDPE plastic. Specifically, it aimed to: (1) isolate the filamentous fungi found in backyard soils; (2) identify the filamentous fungi isolated from backyard soils based on cultural and morphological characteristics; (3) determine which of the identified fungi have the ability to degrade plastic; and (4) determine the percentage of degradation of LDPE plastic using filamentous fungi through weight loss under liquid culture. The fungal isolates were characterized and their cultural and morphological characteristics were used as basis for identification. All fungal isolates were screened for their ability to degrade LDPE plastics using liquid culture technique. Thirty six fungal isolates were obtained from nine backyard soils. Twenty seven of these were identified as Aspergillus, seven were Penicillium, and only one isolate each was Fusarium and Acremonium. In regards to their biodegradation ability, Penicillium sp. 1 has the greatest rate of degradation with 36.93 percent while Acremonium showed the lowest rate of degradation with only 0.29 percent. However, Aspergillus sp. 3 registered a -8.74 percent of degradation, which indicate an increase in the weight of the LDPE plastic used. This implies that Aspergillus sp. 3 developed a biomass in the LDPE plastic.

The study was conducted to screen filamentous fungi isolated from backyard soils for its capability to biodegrade LDPE plastic. Specifically, it aimed to: (1) isolate the filamentous fungi found in backyard soils; (2) identify the filamentous fungi isolated from backyard soils based on cultural and morphological characteristics; (3) determine which of the identified fungi have the ability to degrade plastic; and (4) determine the percentage of degradation of LDPE plastic using filamentous fungi through weight loss under liquid culture.

The fungal isolates were characterized and their cultural and morphological characteristics were used as basis for identification. All fungal isolates were screened for their ability to degrade LDPE plastics using liquid culture technique.

Thirty six fungal isolates were obtained from nine backyard soils. Twenty seven of these were identified as Aspergillus, seven were Penicillium, and only one isolate each was Fusarium and Acremonium. In regards to their biodegradation ability, Penicillium sp. 1 has the greatest rate of degradation with 36.93 percent while Acremonium showed the lowest rate of degradation with only 0.29 percent. However, Aspergillus sp. 3 registered a -8.74 percent of degradation, which indicate an increase in the weight of the LDPE plastic used. This implies that Aspergillus sp. 3 developed a biomass in the LDPE plastic.
