TIBAYAN, YVES ROY M. "In vitro Screening of Low-density Polyethylenebiodegrading Filamentous Fungi Isolated from Soils in Indang, Cavite". Undergraduate Thesis.

Low-density polyethylene (LDPE) plastics are substantial wellsprings of pollution as they are recalcitrant and bioinert materials; thus, they are escalating incessantly in the
environment. Not only the Philippines, but also the other countries have an immense need to search for efficient and economical approach that would be vastly used to degrade these pollutants.
The present work is on the study of LDPE biodegradation by filamentous fungi
obtained from different sampling locations in Indang, Cavite. The isolates were first screened for their biodegrading ability based on abundant growths on Mineral Salt Agar (MSA) amended with LDPE powder. Out of 58 isolates, 28 yielded positive results with abundant growths on MSA after a 30-day incubation. Thereafter, they were subjected to in vilro biodegradation assay on Mineral Salt Broth (MSB) containing LDPE plastic strips for 30 days. The 24 filamentous fungal isolates were phenotypically characterized and were identified belonging to four genera, viz. Aspergillus, Penicillium, Paecilomyces and Helminthosporium; four were not identified.
The three most promising isolates which exhibited more than 20% biodegradation rates were identified as Aspergillus niger, Paecilomyces sp. and Aspergillus niger with
38.70%, 35.96% and 28.78% rates of biodegradation, correspondingly
