A recent breakthrough by researchers at the Royal Netherlands Institute for Sea Research (NIOZ) and collaborators has uncovered a promising solution to ocean plastic pollution. The marine fungus Parengyodontium album has been found to break down polyethylene (PE) plastic, one of the most common and persistent types of plastic waste in the ocean.
Parengyodontium album resides in thin biofilms on ocean plastic and can degrade PE when exposed to ultraviolet (UV) light. This discovery adds the fungus to the short list of known plastic-degrading marine fungi, which includes only three other species to date.
The research, published in Science of the Total Environment, demonstrated that the fungus could degrade PE at a rate of about 0.05% per day. Interestingly, while the fungus breaks down PE, it does not significantly utilize the carbon released; instead, most of it is converted into carbon dioxide, a process similar to human respiration and not considered environmentally harmful.
Crucially, the degradation process by P. album requires prior exposure of the plastic to UV light. This means that the fungus can only degrade plastic that has been floating near the ocean surface where it can be exposed to sunlight. UV light mechanically breaks down the plastic, making it easier for the fungus to further decompose it biologically.
While P. album shows promise, it is unlikely to tackle all oceanic plastic due to its reliance on UV exposure. However, researchers are optimistic that other, yet undiscovered, fungi might also contribute to plastic degradation in deeper ocean layers.
The discovery of Parengyodontium album‘s plastic-degrading capabilities offers a glimmer of hope in the fight against ocean pollution. Continued research is essential to fully understand and harness the potential of marine fungi in mitigating plastic waste in our oceans.
