Evaluating the influence of light intensity in mcyA gene expression and microcystin production in toxic strains of Planktothrix agardhii and Microcystis aeruginosa

Journal of Microbiological Methods, 2016
Cyanobacteria are phytoplanktonic organisms widely occurring in freshwaters, being frequently associated with the production of toxins, namely microcystins (MCs). MCs are produced non-ribosomally by a multienzyme complex (mcy genes). It has been reported that environmental factors, such as light intensity, can influence toxin production.

Genome Mining of Myxopeptins Reveals a Class of Lanthipeptide-Derived Linear Dehydroamino Acid-Containing Peptides from Myxococcus sp. MCy9171.

ACS Chemical Biology, 2023
Myxobacteria exhibit a substantial capacity to produce bioactive natural products. The biosynthetic potential of ribosomally synthesized and post-translationally modified peptides (RiPPs) from myxobacteria remains largely underexplored.

Seasonality of cyanobacteria and eukaryotes in Lake Geneva and the impacts of cyanotoxins on growth of the model ciliate Tetrahymena pyriformis.

Aquatic Toxicology
Toxic cyanobacteria are likely to be favored by global warming and other human impacts, posing significant threats to aquatic ecosystems. While cyanobacterial blooms in eutrophic lakes are widely investigated, the dynamics of cyanobacteria and the ...

Mechanistic study on the increase of Microcystin-LR synthesis and release in Microcystis aeruginosa by amino-modified nano-plastics.

Journal of Hazardous Materials
Ecological risk of micro/nano-plastics (MPs/NPs) has become an important environmental issue. Microcystin-leucine-arginine (MC-LR) produced by Microcystis aeruginosa (M. aeruginosa) is the most common and toxic secondary metabolites (SM).

Harmful algal blooms in Cayuga lake, NY: From microbiome analysis to eDNA monitoring.

Journal of Environmental Management
The global increase in harmful algal blooms (HABs) has become a growing concern over the years, and New York State (NYS) is no exception. The Finger Lakes region in NYS has been identified as a hotspot for HABs, with Cayuga Lake having the highest number
