Insights Into the Efficiency and Health Impacts of Emerging Microplastic Bioremediation Approaches
AI summary Read the abstract
This review summarizes research on using living organisms like bacteria, fungi, and worms to break down microplastics, finding that bioremediation is a promising but still limited approach. Microplastics were detected in human feces (44% of studies), lungs (35%), and blood (17%), confirming widespread human contamination. While biological methods can partially degrade some plastics, no single organism can fully eliminate them, and the byproducts of biodegradation may themselves pose health risks.
The pollution caused by microplastics (MPs) is a global environmental and health concern. These plastic particles disrupt food chains and pose health risks to organisms, including humans. From a total of 827 studies, synthetic textiles (35%) and tires (28%) are the primary sources of MPs, with fibers being the most common shape (60%). MPs were detected in feces (44% of studies), lungs (35%), and blood (17%), indicating widespread contamination and potential health impacts. Bioremediation is a promising and sustainable method for mitigating MP pollution, as it uses microorganisms and plants to break down or convert MPs into less hazardous substances. However, it is important to understand and address the potential unintended consequences of bioremediation methods on the environment and human health. This scoping literature review examines the efficiency of currently emerging approaches for microplastic bioremediation, their strengths and weaknesses, and their potential impacts on the environment and human health. Highly effective methods such as mycoremediation, soil microbes for enhanced biodegradation, and phytoextraction were identified, but they pose high toxicity risks. Moderately effective methods include plant-assisted remediation, rhizosphere degradation, phytodegradation, and biodegradation, with effectiveness rates between 50% and 65% and moderate toxicity risks.

Bioremediation to Overcome Microplastic Contamination in The Water Environment
AI summary Read the abstract
This review examines how living organisms such as bacteria, algae, and worms can be used to break down and remove microplastics from water environments. Researchers evaluated evidence from 23 studies and found that bioremediation shows promise as a sustainable, low-cost approach to addressing microplastic contamination. The study identifies the key factors that influence how well these biological methods work and the challenges that remain before they can be widely deployed.
Microbial Bioremediation of Microplastics
AI summary Read the abstract
Tiny plastic bits called microplastics are now everywhere in our environment—and even in our bodies—raising concerns about long-term health effects. This review paper rounds up what scientists currently know about using bacteria and other microbes to break down these plastic particles, a promising cleanup strategy, while also pointing out the challenges researchers still need to solve before it works at scale. The takeaway: nature may offer tools to help tackle plastic pollution, but we're not there yet, so reducing microplastic use in the first place still matters for protecting our health.
Recent advances in biodegradation of emerging contaminants - microplastics (MPs): Feasibility, mechanism, and future prospects
AI summary Read the abstract
This review explores biological approaches to breaking down microplastics, including using bacteria, fungi, and enzymes. While some organisms can partially degrade certain plastic types, the process is slow and incomplete compared to the scale of pollution. The research is promising for future cleanup efforts but shows that biodegradation alone cannot yet solve the microplastic contamination problem.

Eco‐Friendly Solutions to Emerging Contaminants: Unveiling the Potential of Bioremediation in Tackling Microplastic Pollution in Water
AI summary Read the abstract
This review examines bioremediation -- using microorganisms to break down microplastics in water -- as a greener alternative to costly physical and chemical removal methods. While certain bacteria and fungi show real promise in degrading plastics like polyethylene and polystyrene, challenges remain in scaling these approaches. Reducing microplastics in water is important because contaminated water is one of the main ways these particles reach humans.
