Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

Impact of UV Radiation on Bacterioplankton Community Composition [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT The potential effect of UV radiation on the composition of coastal marine bacterioplankton communities was investigated. Dilution cultures with seawater collected from the surface mixed layer of the coastal North Sea were exposed to different ranges of natural or artificial solar radiation for up to two diurnal cycles ...

In vitro study of the modulatory effects of heat-killed bacterial biomass on aquaculture bacterioplankton communities

Scientific Reports, 2022
Recent studies have shown that the addition of non-viable microbial biomass or their components (postbiotics) to fish feed can modulate the gut microbiome and positively influence fish health in aquaculture systems.

Bacterial Communities in Sand and Seawater of Northern Gulf Coast Beaches: Temporal, Spatial, and Environmental Influences

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Bacterial communities in sand and seawater collected every 3 months from 10 beaches along the Mississippi Gulf coast were fundamentally different from each other. Bacterial communities in both habitats showed more temporal variation over the course of 15 months than spatial variation between beaches. ABSTRACT Coastal microbial communities play critical

Exploring Regional Biogeography of Abundant and Rare Bacteria in Soils With Long‐Read CycloneSEQ

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Background Rare microbial communities represent an important component of biodiversity in soil ecosystems, co‐existing with abundant species to drive ecosystem multifunctionality and maintain its stable operation. However, knowledge remains limited regarding the geographical distribution patterns and potential driving factors of microorganisms,

Stream Hydrological Fragmentation Drives Bacterioplankton Community Composition

PLoS ONE, 2013
In Mediterranean intermittent streams, the hydrological fragmentation in summer and the successive water flow re-convergence in autumn allow exploring how local processes shape the microbial community within the same habitat. The objectives of this study were to determine how bacterial community composition responded to hydrological fragmentation in ...

Impact of treated sewage effluent on the microbiology of a small brook using flow cytometry as a diagnostic tool [PDF]

, 2016
Flow cytometry was applied to assess the microbiological impact of treated sewage effluent discharge into a small brook carrying surface runoff water. Increases in dissolved organic carbon and soluble reactive phosphorous were accompanied by increases in
