Published: May 6, 2023

Overusing non-degradable plastics causes a series of environmental issues, inferring switch to biodegradable plastics. Polyhydroxyalkanoates (PHAs) are promising that can be produced by many microbes using various substrates from waste feedstock. However, the cost PHAs production is higher compared fossil-based plastics, impeding further industrial and applications. To provide guideline for reducing costs, potential cheap feedstock have been summarized in this work. Besides, increase competitiveness mainstream economy, influencing parameters discussed. The degradation has reviewed related type bacteria, their metabolic pathways/enzymes, conditions. Finally, applications different fields presented discussed induce comprehension on practical potentials PHAs.

The effects of climate change and natural disasters on fungal pathogens the risks for diseases remain incompletely understood. In this literature review, we examined how fungi are adapting to an increase in Earth's temperature becoming more thermotolerant, which is enhancing fitness virulence. Climate creating conditions conducive emergence new priming adapt previously inhospitable environments, such as polluted habitats urban areas, leading geographical spread some traditionally non-endemic areas. also contributing increases frequency severity disasters, can trigger outbreaks pathogens. populations mostly affected socially vulnerable. More awareness, research, funding, policies part key stakeholders needed mitigate disaster-related diseases.

Microplastics and their interactions with microbiota

Heliyon, Journal Year: 2023, Volume and Issue: 9(4), P. e15104 - e15104

Published: March 31, 2023

As a new pollutant, Microplastics (MPs) are globally known for their negative impacts on different ecosystems and living organisms. MPs easily taken up by the ecosystem in variety of organisms due to small size, cause immunological, neurological, respiratory diseases impacted organism. Moreover, environments, can release toxic additives act as vector scaffold colonization transportation specific microbes lead imbalances microbiota biogeochemical nutrients dynamic. To address concerns controlling pollution ecosystem, microbial biodegradation be potentially considered an effective environment friendly approach. The objectives presented paper provide information toxicological effects microbiota, discuss MPs, introduce with ability MPs.

Impact of PVC microplastics on soil chemical and microbiological parameters

Environmental Research, Journal Year: 2023, Volume and Issue: 229, P. 115891 - 115891

Published: April 12, 2023

Microplastics (MPs) are emerging pollutants whose occurrence is a global problem in natural ecosystems including soil. Among MPs, polyvinyl chloride (PVC) well-known polymer with remarkable resistance to degradation, and because its recalcitrant nature serious environmental concerns created during manufacturing waste disposal. The effect of PVC (0.021% w/w) on chemical microbial parameters an agricultural soil was tested by microcosm experiment at different incubation times (from 3 360 days). parameters, CO2 emission, fluorescein diacetate (FDA) activity, total organic C (TOC), N, water extractable (WEOC), N (WEN) SUVA254 were considered, while the structure communities studied taxonomic levels (phylum genus) sequencing bacterial 16S fungal ITS2 rDNA (Illumina MiSeq). Although some fluctuations found, microbiological exhibited significant trends. Significant (p < 0.05) variations FDA hydrolysis, TOC, WEOC WEN found PVC-treated soils over times. Considering communities, presence significantly affected abundances specific taxa: Candidatus_Saccharibacteria, Proteobacteria, Actinobacteria, Acidobacteria Bacteroides among bacteria, Basidiomycota, Mortierellomycota Ascomycota fungi. After one year experiment, reduction number dimensions detected supposing possible role microorganisms degradation. abundance both taxa phylum genus level also PVC, suggesting that impact this could be taxa-dependent.

Polystyrene nanoplastics of different particle sizes regulate the polarization of pro-inflammatory macrophages

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: July 15, 2024

Abstract Microplastics (MPs) are defined as plastic particles smaller than 5 mm in size, and nanoplastics (NPs) those MPs with a particle size of less 1000 nm or 100 nm. The prevalence the environment human tissues has raised concerns about their potential negative effects on health. Macrophages major defence against foreign substances intestine, can be polarized into two types: M1 phenotype M2 phenotype. However, effect NPs polarization macrophages remains unclear. Herein, we selected polystyrene, one most plastics controlled sizes at 50 500 respectively to study macrophages. We used mouse RAW264.7 cell line models this macrophage-associated study. Experiments absorption showed that could quickly ingest polystyrene both diameters time-dependent uptake. Compared untreated group 10 μg/mL treatment group, exposed groups (50 nm) had considerably higher levels CD86, iNOS, TNF-α, but decreased aCD206, IL-10, Arg-1. According these findings, macrophage induced inhibited by nanoplastics. This work provided first evidence possible mode action appropriate concentration through production M1, providing dietary environmental recommendations for people, particularly autoimmune autoinflammatory illnesses.
