ClearExploring the Potential of Algae in the Mitigation of Plastic Pollution in Aquatic Environments
This review examined how algae can help mitigate plastic pollution in aquatic environments, finding that certain algal species can adsorb, degrade, or entrap microplastics, suggesting potential bioremediation applications though large-scale effectiveness remains to be demonstrated.
Microalgae for Plastic Biodegradation and Bioplastics Production
This review examines how microalgae biodegrade plastics through enzyme and toxin production while also serving as feedstocks for bioplastic manufacture, exploring both the mechanisms of algal stress from microplastic exposure and the potential of algae-derived biodegradable polymers.
Potential for Using Algae to Reduce Microplastics in the Environment
This review examined the potential of algae to reduce microplastic pollution both by adsorbing and intercepting plastic particles in water and by serving as a feedstock for biosynthesizing biodegradable bioplastics as alternatives to petroleum-based materials.
The role of algae in regulating the fate of microplastics: A review for processes, mechanisms, and influencing factors
This review examines how algae influence the fate of microplastics in aquatic environments through processes including retention, flocculation, deposition, and biodegradation. Researchers found that algae can trap microplastics via adhesion and produce extracellular substances and enzymes that contribute to aggregate formation and partial breakdown of plastic particles, though these interactions are influenced by algal species, microplastic characteristics, and environmental conditions.
Potential for Using Algae to Reduce Microplastics in the Environment
This review described how algae can reduce microplastic pollution through two mechanisms: physical adsorption and entrapment of particles into aggregates that sink, and enzymatic degradation of polymers. Additionally, algae can serve as feedstocks for producing bioplastics, offering a dual role in both plastic remediation and sustainable material production.
Exploring the potential of microalgae in removal of microplastics from the environment and scope of this entity as feedstock for biofuel production
This review explores the potential of microalgae to capture and remove microplastics from aquatic environments, examining the mechanisms by which algal cells adsorb or aggregate plastic particles and discussing the feasibility of algae-based remediation at scale.
Recent Advances in Micro-/Nanoplastic (MNPs) Removal by Microalgae and Possible Integrated Routes of Energy Recovery
This review examined the interactions between micro- and nanoplastics and microalgae, covering how microalgae are affected by plastic particles and how they can in turn be used to remove plastics from aquatic environments. The authors identify microalgae-based systems as promising tools for combined plastic removal and biomass production.
Interplay of plastic pollution with algae and plants: hidden danger or a blessing?
Researchers tested the ability of three microalgae species to remove microplastics from water through bioadhesion, finding that all three species could adsorb particles onto their surfaces. Removal efficiency depended on particle size, surface charge, and algae cell morphology.
Micro/nano-plastics and microalgae in aquatic environment: Influence factor, interaction, and molecular mechanisms.
This review examined the interactions between micro/nanoplastics and microalgae in aquatic environments, summarizing how plastic particle size, surface chemistry, and co-pollutants influence algal toxicity through oxidative stress, photosynthesis inhibition, and gene expression changes.
Nature’s fight against plastic pollution: Algae for plastic biodegradation and bioplastics production
This review explores two algae-based approaches to tackling plastic pollution: using algae to biodegrade existing plastic waste and using algae to produce biodegradable bioplastics. Researchers highlight promising early results showing certain algae species can break down conventional plastics, while algae-derived bioplastics offer a renewable and compostable alternative to petroleum-based materials.
Are algae a promising ecofriendly approach to micro/nanoplastic remediation?
This review examines the potential of algae as an eco-friendly approach to removing micro- and nanoplastics from wastewater treatment plant effluents, covering mechanisms including interception, entanglement, and heteroaggregation. Algae also offer the added benefit of nutrient recovery from wastewater and can be further processed into biochar or biofertilizer.
Bioremediation of Microplastics
This review summarized bioremediation strategies for microplastics, covering microbial degradation by bacteria, fungi, and algae along with enzyme-based approaches. Current limitations in degradation rates and the need for enhanced strains or enzymatic cocktails were discussed.
Evaluating physiological responses of microalgae towards environmentally coexisting microplastics: A meta-analysis
A meta-analysis of 52 studies found that microplastics inhibit microalgal growth and photosynthesis and induce oxidative damage, though microalgae can recover over time. Cyanobacteria are more vulnerable than green algae, and the relative size of microplastics to algal cells governs the mechanism of impact, while aged versus pristine microplastics have opposite effects on extracellular polymeric substance and microcystin production.
Research advances on impacts micro/nanoplastics and their carried pollutants on algae in aquatic ecosystems: A review
This review examines how micro- and nanoplastics harm algae, which are the foundation of aquatic food chains, by slowing growth, reducing photosynthesis, and damaging cells. The effects are worse when microplastics carry other pollutants on their surfaces, creating a combined toxic effect. Since algae support the entire aquatic food web, damage to these organisms can ripple upward through fish and shellfish to affect the safety of seafood consumed by humans.
Microbial Bioremediation of Microplastics
This review examines microbial bioremediation of microplastics, covering the bacteria, fungi, and algae known to degrade different plastic polymers and the enzymes involved. Biological degradation of microplastics offers a potentially scalable approach to reducing plastic contamination in soil and aquatic environments.
Microplastics – An emerging contaminants for algae. Critical review and perspectives
This review examines how microplastics and nanoplastics affect algae, which are the foundation of aquatic food chains. Microplastics can reduce algae growth, disrupt photosynthesis, and cause oxidative stress, with smaller nanoplastics being more harmful. Since algae are at the base of the food web, damage to them can ripple through ecosystems and ultimately affect the seafood that humans consume.
