Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

Diversity, Community Assemblage, and Environmental Determinants of Phytoplankton in a Subtropical Transboundary Coastal River

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study examined spatial and seasonal dynamics of phytoplankton communities in the Dakatia River, identifying 37 genera across six major taxonomic classes, with Bacillariophyceae being the most dominant. Seasonal peaks in phytoplankton abundance and diversity indices indicated higher richness and evenness during winter, while multivariate analyses ...

Physiological and Metabolic Responses of Marine Mussels Exposed to Toxic Cyanobacteria Microcystis aeruginosa and Chrysosporum ovalisporum [PDF]

, 2020
Toxic cyanobacterial blooms are a major contaminant in inland aquatic ecosystems. Furthermore, toxic blooms are carried downstream by rivers and waterways to estuarine and coastal ecosystems. Concerning marine and estuarine animal species, very little is

Insights Into the Distribution of Two Bloom‐Forming Dinoflagellates of Phytosanitary Concern Using Regional and Global Temperature Data

International Review of Hydrobiology, Volume 110, Issue 2, Page 83-89, December 2025.
ABSTRACT Large bloom‐forming dinoflagellates can alter aquatic biodiversity and impact human use, posing conservation challenges. We used the maximum entropy (MaxEnt) model to predict the potential distribution of two Ceratium congeners, C. hirundinella and C.

The Range of the Colonial Microcystis’ Biomass for Shift to Diatom Aggregates Under Aeration Mixing and Low Light

Diversity
In order to investigate non-cyanobacteria dominance succession from Microcystis blooms, particularly to diatom dominance, an experiment using varying colonial Microcystis biomasses expressed as bulk concentrations of 2.0, 4.0, 6.0, 8.0, 10.0, 12.0, 14.0,

Variations of bacterial community during the decomposition of Microcystis under different temperatures and biomass

BMC Microbiology, 2019
Background The decomposition of Microcystis can dramatically change the physicochemical properties of freshwater ecosystems. Bacteria play an important role in decomposing organic matters and accelerating the cycling of materials within freshwater lakes.

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms

Limnology and Oceanography, Volume 70, Issue S2, Page S140-S154, December 2025.
Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a
