Azolla-Anabaena Relationship [PDF]
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]

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.

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 ...

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 ...

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]
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 ...

Growth assessment of cyanobacteria Anabaena Sp. FS 76 and Nostoc Sp. FS 77 affected by thermal shock condition [PDF]
Soil cyanobacteria Nostoc sp. FS 77 and Anabaena sp. FS 76 from the point of view to extreme constraints associated with light, carbon dioxide and cold shock, were evaluated.

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
