Microplastics Degradation Mechanism by Aquatic Plastiomes: A Review
AI summary Read the abstract
Researchers reviewed how aquatic microorganisms can break down plastic debris into microplastics and potentially degrade plastic polymers further, exploring whether natural 'plastisphere' communities might be harnessed as a biological tool to reduce ocean plastic pollution.
Considering the increasing amount of plastic waste in the oceans, it is now obvious that plastic pollution poses a global societal and ecological concern. Discarded plastic pollutants gradually gets fragmented into microplastics (MPs) under the action of various...
