Azolla-Anabaena Relationship [PDF]

open access: yesPlant Physiology, 1987
The major radioactive products of the fixation of [(13)N]N(2) by Azolla caroliniana Willd.-Anabaena azollae Stras. were ammonium, glutamine, and glutamate, plus a small amount of alanine. Ammonium accounted for 70 and 32% of the total radioactivity recovered after fixation for 1 and 10 minutes, respectively. The presence of a substantial pool of [(13)N]

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

open access: yesChemistry &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.

Harnessing Algal Biorefineries for Waste to Wealth Paradigm: A Pathway Toward Circular and Sustainable Bioeconomy

open access: yesCleanMat, Volume 2, Issue 4, Page 297-326, December 2025.
This review highlights the use of wastewater from various sources including industrial, municipal, and agricultural effluents for microalgal cultivation. It emphasizes on the integrated approach of wastewater treatment and microalgal biomass production for high value‐added bioproducts such as biofuels, animal feed, biofertilizers, bioplastics while ...

Specific mutations in the permease domain of septal protein SepJ differentially affect functions related to multicellularity in the filamentous cyanobacterium Anabaena

open access: yesMicrobial Cell, 2018
Filamentous, heterocyst-forming cyanobacteria are multicellular organisms in which growth requires the activity of two interdependent cell types that exchange nutrients and regulators.

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

open access: yesEcology 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 ...

Influence of Plant Genotype on Nodule‐Associated Bacterial Community Composition and Function in Seasonal Field Pea Varieties

open access: yesLegume Science, Volume 7, Issue 4, December 2025.
ABSTRACT Legume root nodules host symbiotic rhizobia that are essential for nitrogen fixation but also harbor diverse non‐rhizobial taxa that remain poorly characterized. Field pea (Pisum sativum) cultivars adapted to distinct seasonal growth (spring and winter) offer an opportunity to explore whether host genotype influences nodule‐associated ...

Molecular and phylogenetic characterization of two species of the genus Nostoc (Cyanobacteria) based on the cpcB-IGS-cpcA locus of the phycocyanin operon [PDF]

open access: yesJournal of BioScience and Biotechnology, 2012
Traditionally, the taxonomy of the genus Nostoc is based on morphological and physiological characters. The extreme morphological variability of the Nostoc species, due to their life cycle and environmental conditions, hampers the correct identification ...

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

open access: yesLimnology 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
