Environmental DNA: Preliminary Characterization of Microbiota in Three Sicilian Lakes. [PDF]

Ecol Evol
Microbial content depends on the origin of the sample. This figure shows the relative abundance of bacteria in three lakes (Poma, Piana, and Scanzano) in Sicily, giving the first insights into microbial communities residing in those environments. ABSTRACT Freshwater ecosystems play a key role in biogeochemical cycles and face various anthropogenic ...

Co-exposure of dimethomorph and imidacloprid: effects on soil bacterial communities in vineyard soil

Frontiers in Microbiology, 2023
In Taiwan, the pesticides dimethomorph and imidacloprid are recommended for pest control in vineyards. Therefore, tank-mixing of these two pesticides is usually a routine practice before application.

Use of Microbial Biofilms to Assess Groundwater Quality in Karstic Ecosystems. [PDF]

Environ Microbiol
Analyses of prokaryotic diversity and community structures of biofilms showed variations linked to the nutrient and organic matter conditions in the studied karstic stations. Biofilms developed on artificial substrates appeared as promising indicators to assess groundwater quality in karst.

16S rRNA gene amplicon-based metagenomic analysis of bacterial communities in the rhizospheres of selected mangrove species from Mida Creek and Gazi Bay, Kenya.

PLoS ONE, 2021
Prokaryotic communities play key roles in biogeochemical transformation and cycling of nutrients in the productive mangrove ecosystem. In this study, the vertical distribution of rhizosphere bacteria was evaluated by profiling the bacterial diversity and

Persistent Circulation of Enterohemorrhagic Escherichia coli (EHEC) O157:H7 in Cattle Farms: Characterization of Enterohemorrhagic Escherichia coli O157:H7 Strains and Fecal Microbial Communities of Bovine Shedders and Non-shedders

Frontiers in Veterinary Science, 2022
Cattle are carriers, without clinical manifestations, of enterohemorrhagic Escherichia coli (EHEC) O157:H7 responsible for life-threatening infections in humans. A better identification of factors playing a role in maintaining persistence of such strains

Osmotic Adaptation and Compatible Solute Biosynthesis of Phototrophic Bacteria as Revealed from Genome Analyses

Microorganisms, 2020
Osmotic adaptation and accumulation of compatible solutes is a key process for life at high osmotic pressure and elevated salt concentrations. Most important solutes that can protect cell structures and metabolic processes at high salt concentrations are

Characterization of External Mucosal Microbiomes of Nile Tilapia and Grey Mullet Co-cultured in Semi-Intensive Pond Systems

Frontiers in Microbiology, 2021
The external mucosal surfaces of the fish harbor complex microbial communities, which may play pivotal roles in the physiological, metabolic, and immunological status of the host.

A Combined Application of Molecular Microbial Ecology and Elemental Analyses Can Advance the Understanding of Decomposition Dynamics

Frontiers in Ecology and Evolution, 2021
Introducing animal carbon-source to soil initiates biochemical and microbial processes that lead to its decomposition and recycling, which subsequently cause successional shifts in soil microbial community.

Metabarcoding Analysis Reveals Microbial Diversity and Its Environmental Drivers in the Pantanos de Villa Lagoons in Lima—Peru [PDF]

Ecol Evol
This study characterized, for the first time, the microbial diversity in four lagoons of the Pantanos de Villa Wildlife Refuge in Lima, Peru, using 16S rRNA marker gene metabarcoding and identified the physicochemical drivers that influence the microbial community structure of these lagoons.

Spatiotemporal and Host Variations in Faecal Microbiomes of Hairy‐Nosed Wombats (Lasiorhinus spp.)

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT The gut microbiome can play a critical role in humans and wildlife, assisting with digestion, immunity and detoxification. This community is often adapted to the animal's ecosystem and fluctuates with seasonal shifts in diet. The gut microbiome can also be altered by anthropogenic effects such as invasive species creating increasingly ...
