Microplastic mixtures are ubiquitously distributed in global ecosystems and include varying types. However, it remains unknown how microplastic diversity affects the biotic interactions of microbes. Here, we developed novel experiments 600 microcosms with ranging from 1 to 6 types examined ecological networks for microbial communities lake sediments after 2 months incubation at 15 20 °C. We found that generally enhanced complexity both temperatures, such as increasing network connectance reducing average path length. This phenomenon was further confirmed by strengthened species toward high except negative Interestingly, temperatures exaggerated effects on structures, resulting higher connectivity interactions. Consistently, using extinction simulations, temperature led more robust networks, their were additionally positively mediated presence biodegradable microplastics. Our findings provide first evidence could unexpectedly promote stability future warming amplify this effect.

Freshwater plastisphere: a review on biodiversity, risks, and biodegradation potential with implications for the aquatic ecosystem health

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: April 18, 2024

The plastisphere, a unique microbial biofilm community colonizing plastic debris and microplastics (MPs) in aquatic environments, has attracted increasing attention owing to its ecological public health implications. This review consolidates current state of knowledge on freshwater focussing biodiversity, assembly, interactions with environmental factors. Current biomolecular approaches revealed variety prokaryotic eukaryotic taxa associated surfaces. Despite their importance, the presence potentially pathogenic bacteria mobile genetic elements (i.e., antibiotic resistance genes) raises concerns for ecosystem human health. However, extent these risks implications remain unclear. Advanced sequencing technologies are promising elucidating functions particularly biodegradation processes. Overall, this emphasizes need comprehensive studies understand plastisphere dynamics support effective management strategies mitigate impact pollution resources.

Biodegradable plastics in Mediterranean coastal environments feature contrasting microbial succession

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 928, P. 172288 - 172288

Published: April 8, 2024

Plastic pollution of the ocean is a top environmental concern. Biodegradable plastics present potential "solution" in combating accumulation plastic pollution, and their production currently increasing. While these polymers will contribute to future marine debris budget, very little known still about behavior biodegradable different natural environments. In this study, we molecularly profiled entire microbial communities on laboratory confirmed polybutylene sebacate-co-terephthalate (PBSeT) polyhydroxybutyrate (PHB) films, non-biodegradable conventional low-density polyethylene (LDPE) films that were incubated situ three coastal environments Mediterranean Sea. Samples from pelagic, benthic, eulittoral habitat taken at five timepoints during an incubation period 22 months. We assessed presence biodegrading bacterial fungal taxa contrasted them against previously published disintegration data polymers. Scanning electron microscopy imaging complemented our molecular data. Putative degraders occurred all environments, but there was no obvious "core" shared plastic-specific microbes. varied between polymers, predominantly selected for underlying communities. Observed patterns did not necessarily match community putative degraders.
