Soil plastispheres as hotspots of antibiotic resistance genes and potential pathogens

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

Estuarine plastisphere as an overlooked source of N2O production

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: July 6, 2022

"Plastisphere", microbial communities colonizing plastic debris, has sparked global concern for marine ecosystems. Microbiome inhabiting this novel human-made niche been increasingly characterized; however, whether the plastisphere holds crucial roles in biogeochemical cycling remains largely unknown. Here we evaluate potential of biotic and abiotic denitrification nitrous oxide (N2O) production estuaries. Biofilm formation provides anoxic conditions favoring denitrifiers. Comparing with surrounding bulk water, exhibits a higher denitrifying activity N2O production, suggesting an overlooked source. Regardless bacterial fungal denitrifications are main regulators instead chemodenitrification. However, contributions bacteria fungi different from those indicating distinct pattern plastisphere. These findings pinpoint as source, provide insights into new biotope Anthropocene.

Exploring the Composition and Functions of Plastic Microbiome Using Whole-Genome Sequencing

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(8), P. 4899 - 4913

Published: March 9, 2021

Besides the ecotoxicological consequences of microplastics and associated chemicals, association microbes on plastics has greater environmental implications as may select for unique microbiome participating in environmentally significant functions. Despite this, functional potential with different types is understudied. Here, we investigate interaction between plastic marine biofilm-forming microorganisms through a whole-genome sequencing approach four incubated environment. Taxonomic analysis suggested that microplastic surfaces exhibit microbial profiles niche partitioning among substrates. In particular, abundance Vibrio alginolyticus campbellii pollution pose risk to food chain negatively impact aquaculture industries. Microbial genera involved xenobiotic compound degradation, carbon cycling, genes type IV secretion system, conjugal transfer protein TraG, plant–pathogen interaction, CusA/CzcA family heavy metal efflux proteins, TolC proteins were significantly enriched all substrates, indicating variety processes operated by plastic–microbiome. The present study gives detailed characterization rapidly altering composition gene pools adds new knowledge surrounding ramifications pollution.
