Circumscription of three new taxa of Merismopedia‐like Cyanobacteria shows how far convergent evolution can go

Journal of Phycology, EarlyView.
Abstract The genus Merismopedia (Merismopediaceae, Chroococcales), characterized by rectangular colonies with cells arranged in regular perpendicular rows and columns, represents a challenging study system due to its limited cultivability. The genus recently underwent taxonomic revision using cultivation‐independent techniques and a polyphasic approach.

Investigation of Microcystin Processing, Production and Export by Microcystis sp. [PDF]

, 2014
During this study, the effect of different processing methods on the microcystin quota (microcystins per cell) was investigated. Microcystins from two Microcystis strains and one Planktothrix strain were quantified using liquid chromatography-mass ...

Applicability of the MTT assay for measuring viability of cyanobacteria and algae, specifically for Microcystis aeruginosa (Chroococcales, Cyanobacteria) [PDF]

, 2007
Several assay methods were screened for viability assessment in cyanobacteria using Microcystis aeruginosa FACHB 905. Compared with fluorescent diacetate (FDA), Evan's Blue and autofluorescence, the 3-[4,5-dimethylthiazol-2-yl]2,5-diphenyl tetrazolium ...

Sustainable control of Microcystis aeruginosa, a harmful cyanobacterium, using Selaginella tamariscina extracts

Ecotoxicology and Environmental Safety
Eco-friendly reagents derived from plants represent a promising strategy to mitigate the occurrence of toxic cyanobacterial blooms. The use of an amentoflavone-containing Selaginella tamariscina extract (STE) markedly decreased the number of Microcystis ...

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 6, Page 2203-2216, November/December 2026.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, Volume 41, Issue 11, Page 1299-1310, November 2026.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.
