Pencemaran lingkungan oleh sampah plastik masih menjadi isu yang tidak berkesudahan karena mengakibatkan biota laut tercemar dan kontaminasi dalam tanah. Penanganan mengenai sampah plastik yang efektif dan efisien dalam berbagai aspek, salah satunya dalam aspek biologis sangat diperlukan. Tujuan penelitian ini adalah mengetahui kemampuan mikroorganisme kapang Aspergillus niger dan jamur Pleurotus sp. dalam mendegradasi plastik LDPE (low density polyethylene). Kultur A. niger dan Pleurotus sp. diinokulasi ke dalam tabung reaksi menggunakan jarum ose. Setelah jamur tumbuh, diinokulasi kembali ke dalam erlenmeyer yang berisikan media molase sebanyak 20 ml. Sampel yang digunakan merupakan plastik jenis LDPE dengan massa per perlakuan sebesar 1 gram dengan ukuran 1×1 cm yang dimasukkan ke labu erlenmeyer berisi molase dan isolat jamur yang telah dikultur sebelumnya. Massa plastik diamati setiap minggu bersamaan dengan perhitungan populasi. Hasil penelitian menunjukkan bahwa penurunan massa plastik yang paling optimal terjadi pada isolat A. niger, dengan persentase penurunan mulai dari minggu kedua sebesar 0,95% dari total penurunan hingga 1,93% di minggu ketiga. Sementara pada isolat Pleurotus sp. mengalami penurunan yang konstan pada minggu pertama hingga kedua, dan penurunan massa plastik terjadi secara drastis di minggu ke tiga dan ke empat dengan persentase penurunan sebesar 1,05% dengan nilai tertinggi 2,23% pada minggu ke empat. A. niger dan Pleurotus sp. mempengaruhi penurunan persentase turunnya degradasi plastik LDPE, masing-masing sebesar 4.41% dan 2.23%.

Biodegradation potential of low-density polyethylene (LDPE) using Aspergillus niger and Phanerochaete chrysosporium

AI summary Read the abstract

Researchers tested two common fungi — Aspergillus niger and Phanerochaete chrysosporium — on low-density polyethylene plastic and found they degraded up to 40% of the material in just 20 days. The findings suggest these fungi could be part of a biological strategy for breaking down one of the world's most common plastic types.

Biodegradation of low-density polyethylene (LDPE) by Aspergillus niger and Aspergillus oryzae

AI summary Read the abstract

This study assessed the ability of two Aspergillus species—A. niger and A. oryzae—to biodegrade low-density polyethylene (LDPE) strips in minimal salt medium over multiple incubation periods. A. oryzae showed greater degradation efficiency (up to 10.22% weight loss), while SEM imaging confirmed fungal colonization and surface erosion including folds, grooves, and cracks in the plastic material.

Determination of Biodegradation Potential of Aspergillus niger, Candida albicans, and Acremonium sclerotigenum on Polyethylene, Polyethylene Terephthalate, and Polystyrene Microplastics

AI summary Read the abstract

Researchers tested the ability of three fungal species to biodegrade polyethylene, polyethylene terephthalate, and polystyrene microplastics over 30 days. Aspergillus niger showed the strongest degradation of polyethylene with 16% weight loss, while other fungi performed better on different plastic types. The study demonstrates that fungal biodegradation is a promising approach for breaking down common microplastics, as confirmed by visible surface changes and chemical alterations in the treated plastics.
