The Role Of Bacteria In Microplastic Bioremediation And Implications For Marine Ecosystems
AI summary Read the abstract
This literature review summarizes how bacteria can be harnessed through bioremediation to break down microplastics in marine environments, cataloging the bacterial species and mechanisms involved. While biological degradation is slow and not yet a practical cleanup solution at scale, identifying effective bacteria is an important step toward developing tools to reduce the long-term accumulation of microplastics in ocean ecosystems.
Microplastics are micro particles <5 mm in size that pose a threat to the survival of organisms living on land and in the ocean. Microplastics contain toxic and carcinogenic or persistent chemicals that will directly or indirectly have a negative impact on marine ecosystems. The process of decomposing waste into microplastics takes a very long time that can take hundreds of years. This can be overcome by the use of bacteria using bioremediation techniques to degrade microplastics in the marine ecosystem. With regard to this, this article aims to review the role of bacteria in degrading microplastics and their impact on marine ecosystems. The method used in this article is a literature review by reviewing related and relevant articles as references. The articles obtained will be sorted according to the topic of the role of bacteria in microplastic bioremediation. Furthermore, it will be analyzed and the results used as a reference for the preparation of this article. The results of the review that the author found were that Pseudomonas , Ochrobactrum, Halomonas sp and Clostridium botulinum bacteria were able to become agents of microplastic degradation in the marine ecosystem.
