The good, the bad and the ugly: Critical insights on the applications of microbes in microplastic degradation
AI summary Read the abstract
This review critically examined the complex roles of microorganisms in microplastic degradation, highlighting both promising microbial capabilities and significant challenges such as slow degradation rates and incomplete mineralization. The paper provided a nuanced assessment of the good, bad, and ugly aspects of deploying microbes as tools against microplastic contamination.
Abstract Microplastic pollution has become a global environmental challenge, with significant impacts on ecosystems and human health. Microbes have emerged as a promising tool in the combating against microplastic contamination. However, the complex relationship between microbes and microplastics presents both opportunities and challenges, leading to a nuanced understanding of their applications in degradation. This paper provides critical insights into the multifaceted roles of different microorganisms in microplastic degradation. It begins by highlighting the ‘good’ aspects, where several strains of microorganisms show the potential to break down microplastics through enzymatic activities and the formation of biofilms. Conversely, the ‘bad’ aspects of microbial involvement in microplastic degradation are examined. Microorganisms can facilitate the transport and bioaccumulation of microplastics in various ecosystems, potentially exacerbating their harmful effects. The ‘ugly’ side of microplastic degradation includes the production of harmful byproducts during microbial breakdown, raising concerns about secondary pollution and toxicity. The concept of plastisphere is discussed in this context, focusing on the phototrophs, photoheterotrophs and heterotrophs. Novel technologies involving microbial degradation of microplastics are also explained. The work emphasises the need for a comprehensive and balanced approach regarding the application of microorganisms in microplastic degradation and remediation.

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.
Harnessing microorganisms for multiscale biodegradation of microplastics and nanoplastics in terrestrial and aquatic environments
AI summary Read the abstract
Tiny plastic particles called microplastics and nanoplastics have spread throughout our soil and water, and scientists once thought they'd stick around forever—but this review of existing research shows certain microbes and environmental conditions (like sunlight, heat, and moisture) can actually break some of them down. This matters because it hints at future cleanup methods using bacteria, fungi, or even plants working with microbes to reduce plastic pollution before it builds up further in our food and water supplies. That said, scientists still don't fully understand how this breakdown happens or whether it's safe and scalable enough to rely on, so more research is needed before this
