Antibiotics in soils may affect the structure and function of microbial communities. In this study, we investigated effects tetracycline on soil community composition production nitrous oxide (N2O) dinitrogen (N2) as end-products denitrification. Grassland were pre-incubated with without for one-week prior to measurements N2O N2 slurries along analysis prokaryotic fungal communities by qPCR next-generation sequencing. Abundance taxonomical bacteria carrying two genotypes reductase genes...
Oil spills are among the most catastrophic events to marine ecosystems and current remediation techniques not suitable for ecological restoration. Bioremediation approaches can take advantage of activity microorganisms with biodegradation capacity thus helping accelerate recovery contaminated environments. The use native increase bioremediation efficiency since they have higher potential survive in natural environment while preventing unpredictable impacts associated introduction non-native...
ABSTRACT The extensive microbial diversity found in the oceans is becoming to be uncovered despite limited knowledge and cultured representatives for many taxonomic groups. This study analysed distribution of Planctomycetota at four water column profiles Eastern North Pacific subtropical front (ENPSF) using 16S rRNA gene sequencing. A dual approach, utilising PacBio long‐reads Illumina short‐reads, was employed enhance accuracy assignment compare sequencing methods. increased below deep...
Nitrification is a vital ecosystem function in the open ocean that regenerates inorganic nitrogen and promotes primary production. Recent studies have shown ecology physiology of nitrifying organisms more complex than previously postulated. The distribution these remote oligotrophic their interactions with physicochemical environment are relatively understudied. In this work, we aimed to evaluate depth profile archaea bacteria Eastern North Pacific Subtropical Front, an area limited...
Recirculating aquaculture systems (RAS) pose unique challenges in microbial community management since they rely on a stable with key target groups, both the RAS environment and host (in this case, Solea senegalensis). Our goal was to determine how much of sole microbiome is inherited from egg stage, acquired during remainder life cycle an production batch, especially regarding potentially probiotic pathogenic groups. work comprises tissue samples 2 days before hatching up 146 after (-2...
The intensification of the poultry industry in last decades has led to a sharp increase number animal processing plants discharging wastewater water bodies. These discharges may have significant effect on environmental quality and important ecosystem functions, such as denitrification. We conducted seasonal survey microcosm experiment an impacted reference tidal creek investigate impacts discharge from plant sedimentary microbial communities, denitrification activity, nitrate removal....
The intensification of the poultry industry may lead to increased spread antibiotic resistance genes (ARGs) in environment. However, impacts wastewater discharge from processing plants on sediment resistome are relatively unexplored. Furthermore, its relationships with important biogeochemical pathways, such as N cycle, virtually unknown. overall objective this study was examine abundance and diversity cycling microbial communities impacted by wastewater. We performed a metagenomic...
ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas and its reduction to dinitrogen by the N2O reductase (encoded nosZ gene) only known biological sink. Within phylogeny there are two major clades (I II), which seem have different ecological niches. However, physiological differences of nosZI nosZII expression that may impact emissions not well understood. Here, we evaluated differential nosZII, both present in Thauera linaloolentis strain 47LolT, response concentration presence...
The monitoring of cities' wastewaters for the detection potentially pathogenic viruses and bacteria has been considered a priority during COVID-19 pandemic to monitor public health in urban environments. methodological approaches frequently used this purpose include deoxyribonucleic acid (DNA)/Ribonucleic (RNA) isolation followed by quantitative polymerase chain reaction (qPCR) reverse transcription (RT)‒qPCR targeting genes. More recently, application metatranscriptomic opened opportunities...
Microbial communities are crucial for important ecosystem functions in the open ocean, such as primary production and nutrient cycling. However, few studies have addressed distribution of microplankton remote oligotrophic region Pacific Ocean. Moreover, biogeochemical physical drivers microbial community structure not fully understood these areas. This research aims to investigate patterns prokaryotic protists communities’ North Subtropical Front (NPSF). The NPSF is a vast with layered...
Keywords: precipitation, aerosols, microorganisms, Antarctica, cloudsClouds and precipitation play an intrinsic role in the global climate, upholding Earth's surface energy equilibrium water cycle. Despite their significance, clouds aerosols over Antarctica Southern Ocean remain poorly understood, primarily due to extreme environment for observations insufficient data. The Antarctic Peninsula (AP) has been exhibiting a significant warming trend last 60 years (Jones et al, 2019). Coupled with...
Abstract Research on the emerging COVID-19 pandemic is demonstrating that wastewater infrastructures can be used as public health observatories of virus circulation in human communities. Important efforts are being organized worldwide to implement sewage-based surveillance SARS-CoV-2 for preventive or early warning purposes, informing preparedness and response measures. However, its successful implementation requires important iterative methodological improvements, well establishment...

Prokaryotic interactions in recirculating aquaculture systems (RAS) environmental communities may play a crucial role driving their functional potential. However, these are often neglected. The aim of this work is to detect prokaryotic Solea senegalensis RAS, through the definition relevant taxa and cluster identification using co-variance co-occurrence tools. Amplicon sequence variants (ASV) were obtained from water, tank biofilm, biofilters two systems, pre-ongrowing weaning, study focuses...
Deep-sea mining may lead to the release of high concentrations metals into surrounding seabed, which can disturb important ecosystem functions provided by microbial communities. Among these, production N2O and its reduction N2 is great relevance since an greenhouse gas. Metal impacts on net deep-sea bacteria are, however, currently unexplored. Here, we evaluated effects cadmium (Cd) a isolate, Shewanella loihica PV-4. We performed series Cd exposure incubations in oxic conditions determined...
