Mismanaged plastics, upon entering the environment, undergo degradation through physicochemical and/or biological processes. This process often results in formation of microplastics (MPs), most prevalent form plastic debris (<1 mm). MPs pose severe threats to aquatic and terrestrial ecosystems, necessitating innovative strategies for effective remediation. Some photosynthetic microorganisms can degrade but there lacks a comprehensive review. Here we examine specific role photoautotrophic water soil environments biodegradation focussing on their unique ability grow persistently diverse polymers under sunlight. Notably, these cells utilise light CO2 produce valuable compounds such as carbohydrates, lipids, proteins, showcasing multifaceted environmental benefits. We address key scientific questions surrounding utilisation nanoplastics (NPs) bioremediation, discussing potential engineering enhanced efficacy. Our review highlights significance alternative biomaterials exploration strains expressing enzymes, polyethylene terephthalate (PET) hydrolases, conjunction with microalgal cyanobacterial metabolisms. Furthermore, delve into promising photo-biocatalytic approaches, emphasising coupling sunlight exposure. The integration microalgal-bacterial consortia is explored biotechnological applications against NPs pollution, synergistic effects wastewater treatment absorption nitrogen, heavy metals, phosphorous, carbon. In conclusion, this provides overview current state research use bioremediation. It underscores need continued investigation development approaches tackle global issue pollution ecosystems.

Terrestrial and Aquatic Plastisphere: Formation, Characteristics, and Influencing Factors

Sustainability, Год журнала: 2024, Номер 16(5), С. 2163 - 2163

The increasing number of plastic particles in the environment gives rise to a unique ecological niche called plastisphere, which is characterized by dynamic assemblage microorganisms comprising autotrophs, heterotrophs, predators, and pathogens. This paper reviews formation, characteristics, factors influencing terrestrial aquatic plastisphere. plastisphere forms when hitchhiking microorganisms, often bacteria, adhere surfaces alter surface properties for subsequent colonization increasingly tightly clinging microorganisms. not as mobile defined characteristics soil anchoring it. on are dominant surroundings, particularly those phyla Proteobacteria, Actinobacteria, Bacteroidota, Firmicutes, Chloroflexi, Acidobacteria, Cyanobacteria, Ascomycota, Basidiomycota, Chytridiomycota, Ciliophora, Ochrophyta, Chlorophyta. However, compositions microbial species different vary widely they change with time, properties, biotic abiotic environmental factors. Temporal changes due succession. Plastic type, size, color, degree aging, chemical leaching, also affect composition Biotic ambient interspecies interactions, together ones, including pH, temperature, nutrient availability, salinity, light, significantly shape review provides insight into biodiversity its roles spreading pathogens degrading plastics.

Isolation and Identification of Bacterial Strains Colonizing the Surface of Biodegradable Polymers

Microorganisms, Год журнала: 2025, Номер 13(3), С. 609 - 609

Опубликована: Март 6, 2025

Plastics play a key role in every sector of the economy, being used manufacturing products fields health, food packaging, and agriculture. Their mismanagement poses serious threat to ecosystems and, general, human life. For this reason, particular attention has been paid last decade use biodegradable polymers (BPs) as an alternative classic plastics. In study, we aimed identify bacterial strains able colonize surface five BPs: poly(butylene succinate) (PBS), succinate-co-butylene adipate) (PBSA), poly(ε-caprolactone), (PCL), poly(3-hydroxybutyrate) (PHB), poly(lactic acid) (PLA). experiment, mesocosms were designed ad hoc mimic conditions which can be found marine environments: i. suspended water column; ii. laying over gravel; iii. under gravel. Four samples taken (3, 4, 10, 12 months from start experiment) BPs incubated above-mentioned three conditions. Our results demonstrated that bacteria belonging Proteobacteria, Actinobacteria, Firmicutes, Bacillota, Bacteroidota, Cyanobacteria phyla most frequent colonizers surfaces analysis, could responsible for their degradation, resulting evolution strategies degrade plastics through secretion specific enzymes.

Degradation and habitat-dependent colonization of plastics in Caribbean coastal waters and sediments by bacterial communities

Marine Pollution Bulletin, Год журнала: 2025, Номер 214, С. 117787 - 117787

This study investigates microbial colonization of plastics in Caribbean coastal waters. We deployed five polymer types, on set with a mild UV-pretreatment and one without UV-pretreatment, for 4.5 months the water column sediment at two locations, analyzed epiplastic biofilms 16S rRNA gene sequencing. While significant influence location habitat was apparent, we could not detect notable effects related to type or community composition. Nevertheless, potential plastic hydrocarbon degraders constituted up 43 % sequences from biofilms, suggesting an affinity plastic. Indeed, utilizing 13C-labeled PE PP, determined incorporation plastic-derived carbon into biomass. measured isotopically labeled fatty acids incubations 13C both sediments, whether virgin pre-weathered UV light. The apparent biodegradation benthic habitats challenges perception marine sediments as final sink polyolefins.
