Microplastic-Degrading Microorganisms: An Emerging Frontier in Environmental Microbiology
AI summary Read the abstract
Scientists are studying special bacteria, fungi, and algae that can actually "eat" microplastics by breaking them down with natural enzymes—this matters because microplastics are now found everywhere, including inside our bodies, and current cleanup methods aren't working well enough. This review pulls together existing research on these plastic-munching microbes and highlights promising advances, like an AI-engineered enzyme that speeds up plastic breakdown, though scientists note real-world cleanup is still slow and faces major hurdles before it can be used at large scale.
Microplastics (MPs), plastic particles smaller than 5 mm, have emerged as ubiquitous and persistent environmental contaminants of global concern.Their pervasive presence in terrestrial, aquatic, and atmospheric compartments poses significant ecological and public health risks.Conventional physicochemical remediation strategies have proven inadequate at scale, necessitating the exploration of sustainable biological alternatives.This comprehensive review examines the diversity of microplastic-degrading microorganisms including bacteria, fungi, yeasts, algae, and cyanobacteria their enzymatic degradation mechanisms, biochemical degradation pathways, and the ecological dynamics of the plastisphere biofilm community.Key genera including Ideonella, Pseudomonas, Bacillus, Rhodococcus, Aspergillus, Trametes, and Penicillium are discussed with reference to the specific enzymes they deploy against distinct polymer types.The roles of hydrolytic enzymes (PETase, MHETase, cutinases, lipases) and oxidative enzymes (laccases, peroxidases, alkane hydroxylases) are critically analyzed alongside recent protein engineering advances, including AI-guided directed evolution yielding the high-efficiency FAST-PETase variant.The influence of environmental parameters temperature, pH, UV radiation, nutrient availability, and plastic crystallinity on degradation efficiency is systematically reviewed.Current challenges, including slow degradation rates, polymer recalcitrance, additive toxicity, and scale-up barriers, are identified and future directions encompassing synthetic biology, metagenomics, and circular biorefinery concepts are critically discussed.

Microbial plastic and microplastic bioremediation and innovations
AI summary Read the abstract
Scientists are studying certain bacteria and fungi that can naturally "eat" plastic, breaking it down using special enzymes instead of letting it pile up in landfills and oceans. This review paper rounds up what researchers have learned so far, including new tech that could speed up this microbial cleanup process, but notes there are still real challenges before it can be used on a large scale. This matters because as plastic waste breaks down into microplastics that contaminate our water, food, and even our bodies, finding safer ways to eliminate plastic pollution could reduce our long-term exposure to these particles.
Plastic pollution and its global environmental impacts: a comprehensive review of microbial biodegradation mechanisms, plastic-degrading enzymes, emerging biotechnological strategies and artificial intelligence-driven approaches for sustainable plastic waste management
AI summary Read the abstract
This review pulls together current research on using bacteria and enzymes to break down plastic waste instead of relying on landfills or incineration, which are costly and create their own pollution. Scientists are now pairing this "microbial recycling" with artificial intelligence to speed up the discovery of plastic-eating enzymes, though the technology still needs more real-world testing before it can be scaled up. This matters because plastic waste breaks down into micro- and nanoplastics that are turning up in our water, food and even our bodies, so finding better ways to eliminate plastic waste could reduce our long-term exposure to these particles.
Plastic-Degrading Microorganisms: Biodegradation Pathways and Habitat Origins
AI summary Read the abstract
Scientists have found that certain bacteria and fungi—living in places like landfills, soil, and compost—naturally produce enzymes that can break down different types of plastic, essentially "eating" them as food. This matters because plastic pollution (including the microplastics we're increasingly exposed to in food, water, and air) is a growing health concern, and these microbes could offer a natural, eco-friendly way to clean up plastic waste instead of relying on landfills or incineration. This paper is a review, meaning it summarizes and organizes findings from existing studies rather than presenting brand-new experiments.
Microplastics in the Environment
AI summary Read the abstract
Microplastics—tiny plastic fragments from everyday products—are piling up in our air, water, and food, and scientists are increasingly concerned about their effects on wildlife and human health. This review paper (which summarizes existing research rather than presenting new experiments) explores how certain bacteria and enzymes might be able to break down these plastics naturally, offering a promising but still-developing solution to plastic pollution. While this "eating plastic" approach isn't ready for widespread use yet, it highlights a potential path toward reducing the microplastics that end up in our environment and, ultimately, our bodies.
Microbial enzyme power: Breaking down microplastics for a cleaner planet
AI summary Read the abstract
This review examines how microbial enzymes produced by bacteria, fungi, and algae can break down and degrade microplastic polymers. The study suggests that enzymatic biodegradation represents a promising and more sustainable alternative to conventional microplastic removal methods, though further research is needed to improve enzyme efficiency and scalability.
