ClearBiodegradation of typical plastics and its mechanisms
This review summarizes the mechanisms by which common plastic types are broken down by bacteria, fungi, and other microorganisms in the environment. Despite their chemical stability, many plastics can be degraded — though slowly — with the pace depending on environmental conditions and plastic type. The paper provides a foundation for developing faster biodegradation strategies to reduce plastic pollution.
Characteristic Features of Plastic Microbial Degradation
This book chapter reviews the characteristics of microbial plastic degradation, covering the enzymes, metabolic pathways, and environmental conditions that affect breakdown rates for different polymer types. Understanding microbial degradation mechanisms is foundational to developing biological solutions for microplastic pollution.
Biodegradation of macro- and micro-plastics in environment: A review on mechanism, toxicity, and future perspectives.
This review examined mechanisms, toxicology, and future perspectives for biodegradation of macro- and micro-plastics, cataloguing microbial species capable of polymer degradation, discussing enzymatic pathways, and identifying key limitations including slow degradation rates and the need for pretreatment to accelerate breakdown in environmental settings.
Microbial degradation of plastic-A brief review
This review examined microbial degradation of plastics, surveying known plastic-degrading bacteria and fungi and the enzymes they produce, while acknowledging that degradation rates in natural environments remain extremely slow and that biotechnology approaches to accelerating biodegradation require further development.
Review on the Biological Degradation of Polymers in Various Environments
This review provides an overview of how biodegradable plastics degrade under different environmental conditions including soil, freshwater, marine, and composting environments. It finds that biodegradability is a material property strongly dependent on environmental conditions, and that many so-called biodegradable plastics degrade far more slowly in nature than in controlled test conditions.
Microbial Degradation of Plastics
This review examines microbial degradation of plastics in the environment, discussing how environmental breakdown of plastics generates microplastic particles that accumulate in plants and animals and cause metabolic disruptions, while exploring the potential of microorganisms to break down plastic polymers.
A Review on Natural Biodegradation of Plastics
This review examines the natural biodegradation of plastics in soil and water environments by microorganisms and photochemical processes, discussing why conventional disposal methods are insufficient for addressing the growing global plastic waste problem. The paper distinguishes between plastics that are highly sensitive to microbial degradation and those that remain stable in natural environments, reviewing the mechanisms and limitations of biological breakdown.
Classification and microbes involved in Plastic biodegradation: A review
This review classifies types of plastics and catalogues the bacteria, fungi, and other microbes involved in plastic biodegradation, examining enzymatic mechanisms and conditions that facilitate microbial breakdown of synthetic polymers. The authors argue that microbial biodegradation offers a more sustainable and less hazardous alternative to physical and chemical disposal methods such as landfill and incineration.
Mechanisms of interaction between microplastics and microorganisms in the environment
This review summarized the sources, environmental distribution, and hazards of microplastics, focusing on how MPs influence both individual microorganisms and microbial communities in the environment. Microbial degradation pathways and methods were analyzed, and future research directions proposed to better understand the environmental behavior of microplastics and their interactions with microorganisms.
Microbial plastic degradation: enzymes, pathways, challenges, and perspectives.
This review synthesizes current knowledge on microbial plastic degradation, covering the enzymes and metabolic pathways involved in breaking down major synthetic polymers, the challenges limiting efficient biodegradation, and perspectives for engineering improved microbial solutions to plastic waste.
Microbial Degradation of Plastic Polymers
This review examines microbial degradation pathways for common synthetic plastics including polyethylene, polypropylene, polystyrene, PVC, polyurethane, and PET, describing how mechanical and biological processes fragment plastics into microplastics and how microorganisms can be leveraged to address plastic pollution in aquatic and terrestrial environments.
Microbial degradation of plastics: Biofilms and degradation pathways
This review covers how microorganisms form biofilms on plastic surfaces in soils and water, and how these communities gradually break plastics down through enzymatic activity. Microbial plastic degradation is still slow and incomplete, but understanding the process is key to developing biological plastic cleanup strategies.
Microbial Degradation of Plastics
This review covers microbial species capable of degrading synthetic plastics, examining the enzymes and metabolic pathways involved and the environmental conditions that influence breakdown rates. While microbial degradation offers a promising long-term remediation strategy, the review concludes that current rates are far too slow to address the scale of plastic accumulation in the environment.
Role of Biofilms in the Degradation of Microplastics
This review examines the role of microbial biofilms in degrading microplastics, presenting insights into how microbial communities colonizing plastic surfaces may contribute to the breakdown of microplastic particles in aquatic and terrestrial environments.
Biodegradable plastics in the marine environment: a potential source of risk?
This review examines whether biodegradable plastics offer a genuine solution to marine plastic pollution, finding that their environmental behavior depends heavily on specific conditions and that they may still pose risks in marine environments where decomposition is slow.
The Role of Soil Microorganisms in Microplastic Biodegradation: Mechanisms, Carbon Preferences, and Ecological Impacts
This review examines how soil microorganisms interact with microplastics and attempt to biodegrade them, finding that despite plastics being carbon-based, their unique chemical structures prevent microbes from using them the same way they use natural organic matter. Soil carbon availability affects which microbes preferentially colonize and partially break down plastic particles, but full assimilation remains limited. Understanding microbial degradation pathways is important for assessing how long microplastics persist in soils and for developing bioremediation strategies.
Microbial Degradation and Valorization of Plastic Wastes
This review covers recent advances in microbial and enzymatic degradation of synthetic plastic wastes, summarizing the microorganisms and enzymes capable of attacking different polymer types and assessing the prospects for biological plastic waste treatment at scale.
[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
In-soil degradation of polymer materials waste – A survey of different approaches in relation with environmental impact
This review surveys the in-soil degradation of polymer materials — including natural fibers, synthetic plastics, and composites — examining how environmental factors such as UV radiation, microorganisms, moisture, and temperature drive degradation and influence the environmental impact of plastic waste in terrestrial ecosystems.
Biodegradation of plastic by some Microorganisms as influenced by Chemical factors
This study examined microbial and enzymatic biodegradation of plastic materials, testing which fungi and bacteria can break down common plastics under various chemical conditions. Fungi like Penicillium and Aspergillus showed capacity to degrade plastic, offering potential biological pathways for plastic waste management.
