Micropollutants are ubiquitously found in natural surface waters and pose a potential risk to aquatic organisms. Stream biofilms, consisting of bacteria, algae other microorganisms potentially contribute bioremediating environments by biotransforming xenobiotic substances. When investigating the stream biofilms remove micropollutants from water column, it is important distinguish between different fate processes, such as biotransformation, passive sorption active bioaccumulation. However, due complex nature biofilm community its extracellular matrix, this task often difficult. In study, we combined biotransformation experiments involving collected up- downstream wastewater treatment plant outfalls with QuEChERS extraction method processes. The proved be suitable for broad range (> 80% investigated compounds). We that 31 out 63 compounds were biotransformed majority being substitution-type biotransformations, have an increased towards specific wastewater-relevant micropollutants. Overall, using experimental analytical strategy developed, demonstrated inherent micropollutant potential, thus bioremediation improving ecosystem health.

Abstract Biofilms are matrix‐enclosed communities that represent the most dominant and active mode of microbial life on Earth. Because biofilms inherently more productive than any equivalent planktonic community, they great relevance to all environments inhabit. However, their existence importance still poorly known by general public, conservation practitioners environmental policymakers. Most micro‐organisms multicellular organisms (including humans, animals plants) occur in form true or biofilm‐like structures play vital roles development, physiology immunity. Conversely, some can have a negative effect host health. growing non‐biological surfaces essential components many terrestrial marine ecosystems: basis food webs ensure nutrient cycling bioremediation natural systems. promote persistence human pathogens, produce harmful toxins, foul corrode man‐made settings; which significant health economic implications. There is knowledge gap about epidemiology wildlife emerging infectious diseases, yet these pose major threat public health, biodiversity sustainability. The drivers global change affect biofilm structure functions. consequences for ecosystem are, however, understood. While concept healthy microbiome (as opposed dysbiosis) medicine biology, remains be defined sciences. Here, we use an integrative approach (a) review current biological interfaces ecosystems, (b) provide future research directions address identified gaps.

Wastewater treatment plants (WWTPs) play an important role in retaining organic matter and nutrients but to a lesser extent micropollutants.Therefore, treated wastewater is recognized as major source of multiple stressors, including complex mixtures micropollutants.These can potentially affect microbial communities the receiving water bodies ecological functions they provide.In this study, we evaluated flow-through channels consequences exposure mixture stream different percentages urban WWTP effluent, ranging from 0% 80%, on diversity function periphyton communities.Assuming that micropollutants exert selective pressure for tolerant microorganisms within communities, further examined sensitivity micropollutant extracted passive samplers were immersed effluent.As well, comprehensively quantified.Our results show detected differed those found water, both term concentration composition.Especially photosystem II inhibitors accumulated more than other pesticides.Although effects substances cannot be excluded, accumulation may have contributed observed higher tolerance phototrophic upon 30% 80% wastewater.On contrary, no difference was heterotrophic communities.Exposure gradient led structural differences prokaryotic eukaryotic communities.For instance, relative abundance cyanobacteria with increasing percentage whereas opposite diatoms.Such could indicate community structure do not necessarily lead tolerance.This highlights need consider constituents such wastewater-derived modulate tolerance.By using engineered mimic some required field conditions development periphyton, our study constitutes base investigate mechanisms underlying increased tolerance, potential originating effluents, options reduce load effluents.

Environmental pollution is one of the main challenges faced by humanity. By their ubiquity and vast range metabolic capabilities, microorganisms are affected with consequences on host organisms functioning environment. They also play key roles in fate pollutants through degradation, transformation, transfer organic or inorganic compounds. Thus, they crucial for development nature-based solutions to reduce bio-based environmental risk assessment chemicals. At intersection between microbial ecology, toxicology, biogeochemistry, ecotoxicology a fast-expanding research area aiming decipher interactions microorganisms. This perspective paper gives an overview identified Ecotoxicomic network within emerging One Health framework light ongoing interest biological approaches remediation current state art ecology. We highlight prevailing knowledge gaps pitfalls exploring complex among environment context chemical pinpoint areas where future efforts needed.
