Biodegradation of Typical Plastics: From Microbial Diversity to Metabolic Mechanisms

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(1), С. 593 - 593

Опубликована: Янв. 2, 2024

Plastic production has increased dramatically, leading to accumulated plastic waste in the ocean. Marine plastics can be broken down into microplastics (<5 mm) by sunlight, machinery, and pressure. The accumulation of organisms release additives adversely affect health marine organisms. Biodegradation is one way address pollution an environmentally friendly manner. microorganisms more adapted fluctuating environmental conditions such as salinity, temperature, pH, pressure compared with terrestrial microorganisms, providing new opportunities pollution. Pseudomonadota (Proteobacteria), Bacteroidota (Bacteroidetes), Bacillota (Firmicutes), Cyanobacteria were frequently found on biofilms may degrade plastics. Currently, diverse plastic-degrading bacteria are being isolated from environments offshore deep oceanic waters, especially Pseudomonas spp. Bacillus Alcanivoras Actinomycetes. Some fungi algae have also been revealed degraders. In this review, we focused advances biodegradation their enzymes (esterase, cutinase, laccase, etc.) involved process polyethylene terephthalate (PET), polystyrene (PS), (PE), polyvinyl chloride (PVC), polypropylene (PP) highlighted need study sea.

Microplastic pollution as an environmental risk exacerbating the greenhouse effect and climate change: a review

Carbon Research, Год журнала: 2024, Номер 3(1)

Опубликована: Янв. 26, 2024

Abstract Microplastics are polymer-based materials with carbon as their main framework. During degradation, they release greenhouse gases such dioxide and methane. Additionally, environmental microplastics can enter plant tissues, triggering oxidative stress in cells, adversely affecting photosynthesis, metabolism, gene expression, other growth parameters. This reduction efficiency sequestering utilizing atmospheric indirectly impacts global cycling, exacerbating the effect. Furthermore, significantly alter soil structure composition of microbial communities, emissions dioxide, methane, nitrous oxide, thus promoting gas emissions. Increasing research suggests a mutual reinforcement between microplastic pollution climate warming, where exacerbates rise average temperature leads to resuspension sediments, intensifying environment. article primarily focuses on different ecosystems relationship warming. It summarizes effects marine, terrestrial, ecosystems, well mechanisms by which change affect ecosystem services. By delving into intricate connection emissions, this paper aims raise awareness caused calls for further change, ultimate goal protecting human health. Graphical

Magnetic Microrobot Swarms with Polymeric Hands Catching Bacteria and Microplastics in Water

ACS Nano, Год журнала: 2024, Номер 18(20), С. 13171 - 13183

Опубликована: Май 8, 2024

The forefront of micro- and nanorobot research involves the development smart swimming micromachines emulating complexity natural systems, such as swarming collective behaviors typically observed in animals microorganisms, for efficient task execution. This study introduces magnetically controlled microrobots that possess polymeric sequestrant "hands" decorating a magnetic core. Under influence external fields, functionalized beads dynamically self-assemble from individual microparticles into well-defined rotating planes diverse dimensions, allowing modulation their propulsion speed, exhibiting motion. These mobile microrobotic swarms can actively capture free-swimming bacteria dispersed microplastics "on-the-fly", thereby cleaning aquatic environments. Unlike conventional methods, these be collected complex media release captured contaminants second vessel controllable manner, is, using ultrasound, offering sustainable solution repeated use decontamination processes. Additionally, residual water is subjected to UV irradiation eliminate any remaining bacteria, providing comprehensive solution. In summary, this shows microrobot design

Frequently used protective items during the pandemics are prepared from plastics products, such as polypropylene, polyurethane, polyacrylonitrile, polystyrene, polycarbonate, polyethylene, and polyester. Globally more than 57 million pounds of personal equipment along with other biomedical plastic waste entering into oceans per annum. Lots economic benefits can be obtained by recycling polymeric wastes converting them useful products through, reduced manufacture cost, bio converted cleaner environment developing a circular management model. Personal equipment's different outer most surface these free-floating presents in aquatic serve colonization support to diverse microbial populations known plastisphere. Microbial starts an initial attachment under environmental conditions, subsequently permanent association on surface. The community structure microorganisms plastisphere significantly influenced depth water ecosystem where microplastics present nutrients availability. As have been deeply investigated for their role biodegradation several pollutants, review article focuses diversity ecosystem, underlying mechanism colonization, potential microplastic degradation.

Novel functional insights into the microbiome inhabiting marine plastic debris: critical considerations to counteract the challenges of thin biofilms using multi-omics and comparative metaproteomics

Microbiome, Год журнала: 2024, Номер 12(1)

Опубликована: Фев. 22, 2024

Microbial functioning on marine plastic surfaces has been poorly documented, especially within cold climates where temperature likely impacts microbial activity and the presence of hydrocarbonoclastic microorganisms. To date, only two studies have used metaproteomics to unravel genotype-phenotype linkages in 'plastisphere', these revealed dominance photosynthetic microorganisms warm climates. Advancing functional representation plastisphere is vital for development specific databases cataloging diversity associated their peptide protein sequences, fuel biotechnological discoveries. Here, we provide a comprehensive assessment metaproteomics, using multi-omics data mining thin biofilms unique insights into metabolism. Our robust experimental design assessed DNA/protein co-extraction cell lysis strategies, proteomics workflows, diverse search databases, resolve active taxa expressed functions from an understudied environment.
