Abundance, Diversity and Metabolomic Profiles of Soil Cyanobacteria-Dominated Microbial Communities Under Long-Term Differential Management in an Olive Orchard. [PDF]

Environ Microbiol
Sustainable management in a semi‐arid olive orchard increased abundance and diversity of nitrogen‐fixing cyanobacteria, shifting dominance towards Nodosilinea and Nostoc, while conventional soils were dominated by Leptolyngbya. Metabolomics showed stress‐related lipid and vitamin production under conventional management versus enhanced amino acids and ...

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States). [PDF]

J Phycol
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).
