Abstract In the Anthropocene, increasing pervasive plastic pollution is creating a new environmental compartment, plastisphere. How plastisphere affects microbial communities and antibiotic resistance genes (ARGs) an issue of global concern. Although this has been studied in aquatic ecosystems, our understanding microbiota soil ecosystems remains poor. Here, we investigated ARGs four types microplastics (MPs) from diverse environments, revealed effects manure, temperature, moisture on them. Our results showed that MPs select for plastisphere, these are involved metabolic pathways, indicating they could drive ecological processes ecosystem. The relationship within bacterial zero-radius operational taxonomic units (zOTUs) was predominantly positive, neutral appeared to dominate community assembly. However, deterministic were more important explaining variance plastispheres. A range potential pathogens detected which enriched compared but varied across types. We further found addition manure elevation temperature all enhance plastispheres, increase with moisture. These suggested plastispheres habitats increased pathogen abundance spatially co-located under change. findings provided insights into ecology microbiome resistome

Marine microplastic pollution is a growing problem for ecotoxicology that needs to be resolved. In particular, microplastics may carriers of “dangerous hitchhikers,” pathogenic microorganisms, i.e., Vibrio . Microplastics are colonized by bacteria, fungi, viruses, archaea, algae and protozoans, resulting in the biofilm referred as “plastisphere.” The microbial community composition plastisphere differs significantly from those surrounding environments. Early dominant pioneer communities belong primary producers, including diatoms, cyanobacteria, green bacterial members Gammaproteobacteria Alphaproteobacteria With time, mature, diversity increases quickly include more abundant Bacteroidetes than natural biofilms. Factors driving environmental conditions polymers, with former having much larger influence on polymers. Microorganisms play key roles degradation plastic oceans. Up now, many species, especially Bacillus Pseudomonas well some polyethylene degrading biocatalysts, have been shown capable microplastics. However, relevant enzymes metabolisms need identified. Here, we elucidate potential quorum sensing research first time. Quorum become new area understand promote ocean.

The cryosphere is the term used to describe frozen areas of Earth, including all forms snow and ice, which are primarily influenced by anthropogenic pollutants through atmospheric transport. In this review, we described current status newly emergent pollutant-microplastics-in ice typical cryospheric regions (e.g., Arctic, Antarctic, Alps, Tibetan Plateau, Andes), discussed their transport pathways, provided perspectives for future research. A brief summary sampling, pretreatment, identification microplastics in suggested that standard procedures were inadequate urgently required improvement. Microplastics widely distributed across regions, indicating ubiquitous distribution such environments. However, abundance, size distribution, shape, polymer composition showed significant differences.

Global economies depend on the use of fossil-fuel-based polymers with 360-400 million metric tons synthetic being produced per year. Unfortunately, an estimated 60% global production is disposed into environment. Within this framework, microbiologists have tried to identify plastic-active enzymes over past decade. Until now, research has largely failed deliver functional biocatalysts acting commodity such as polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC), ether-based polyurethane (PUR), polyamide (PA), polystyrene (PS) and rubber (SR). However, few are known act low-density low-crystalline (amorphous) terephthalate (PET) ester-based PUR. These above-mentioned represent >95% all plastics produced. Therefore, main challenge currently facing in finding polymer-active targeting majority plastics. identifying either implement them biotechnological processes or understand their potential role nature emerging field. The application these still its infancy. Here, we summarize current knowledge microbial enzymes, distribution impact plastic degradation industrial nature. We further outline major challenges novel optimizing ones by approaches problems arising through falsely annotated unfiltered database entries. Finally, highlight applications possible re- upcycling concepts using microorganisms.

Microplastic (MP) pollution is of great environmental concern. MPs have been found all over the Earth, including in poles, which indicative for important threat they constitute. Yet, while ocean object major interest, data available literature about MP freshwaters Earth's poles are still limited. Here, we review current knowledge Arctic, Antarctica and Third Pole, assess its ecological implications. This highlights presence lakes, rivers, snow, glaciers investigated sites, questions transport patterns through reach these remote areas, illustrates that a real problem not only marine systems, but also freshwater environments poles. can indeed be ingested by animals physically damage their digestive tracts, as well escalate trophic levels. alter microbial communities serving surfaces onto microbes grow develop, enhance ice melting when trapped glaciers. Hence, considered limited available, encourage more research on theme.

Southeast Asia is considered to have some of the highest levels marine plastic pollution in world. It therefore vitally important increase our understanding impacts and risks ecosystems essential services they provide support development mitigation measures region. An interdisciplinary, international network experts (Australia, Indonesia, Ireland, Malaysia, Philippines, Singapore, Thailand, United Kingdom, Vietnam) set a research agenda for region, synthesizing current knowledge highlighting areas further Asia. Using an inductive method, 21 questions emerged under five non-predefined key themes, grouping them according which: (1) characterise Asia; (2) explore its movement fate across region; (3) describe biological chemical modifications undergoes; (4) detail environmental, social, economic impacts; and, finally, (5) target regional policies possible solutions. Questions relating these priority highlight importance better pollution, degradation, it can generate communities different ecosystem services. Knowledge aspects will help actions which currently suffer from transboundary problems, lack responsibility, inaction tackle issue point source Being profoundly affected by Asian countries opportunity test effectiveness innovative socially inclusive changes governance, as well both high low-tech solutions, offer insights actionable models rest
