Study on a novel omnidirectional ultrasonic cavitation removal system for Microcystis aeruginosa

Ultrasonics Sonochemistry, 2022
Microcystis aeruginosa, as a typical alga, produces microcystin with strong liver toxicity, seriously endangering the liver health of human and animals. Inhibiting the bloom of the Microcystis aeruginosa in lakes becomes a significant and meaningful work.

Allelopathic Inhibition and Mechanism of Quercetin on Microcystis aeruginosa. [PDF]

Plants (Basel), 2023
The utilization of allelochemicals to inhibit algal overgrowth is a promising approach for controlling harmful algal blooms (HABs). Quercetin has been found to have an allelopathic effect on algae. However, its responsive mechanism needs to be better understood.

Harmful algal bloom species Microcystis aeruginosa releases thiamin antivitamins to suppress competitors [PDF]

mBio
In environmental ecosystems, vitamin concentrations are often exceedingly low, and auxotrophy, or reliance on exogenous vitamins or vitamin precursors, is widespread.

Oxidation of <i>Microcystis aeruginosa</i> and Microcystins with Peracetic Acid. [PDF]

Toxins (Basel)
Peracetic acid (PAA) shows potential for use in drinking water treatment as an alternative to prechlorination, such as for mussel control and disinfection by-product precursor destruction, though its impact as a preoxidant during cyanobacterial blooms remains underexplored.

Effect of photoreactivation on ultraviolet inactivation of Microcystis aeruginosa

Water Science and Technology, 2011
Microcystis aeruginosa forms algal bloom in lakes. They produce toxic compounds such as microcystin. Against such algal problems, the effect of UV treatment was examined. In UV treatment, the effect of photoreactivation should be examined. Photoreactivation is a repair mechanism of genomic DNA damage by sunlight irradiation.

Dog Poisonings Associated with a Microcystis aeruginosa Bloom in the Netherlands [PDF]

Toxins, 2013
In early autumn 2011, three dogs died after they had been exposed to a Microcystis aeruginosa bloom on Lake Amstelmeer, The Netherlands. The cyanobacterial scum from the lake contained up to 5.27 × 103 μg g−1 dry-weight microcystin, the vomit of one of ...

The Allelopathic Inhibition of Submerged Macrophytes (Ceratophyllum demersum and Myriophyllum spicatum) in Response to Toxic and Non-Toxic Microcystis aeruginosa [PDF]

Microorganisms
The present study systematically explored the purification effects and response of submerged plants, Ceratophyllum demersum and Myriophyllum spicatum, on toxic and non-toxic strains of Microcystis aeruginosa via indoor co-culture experiments. The results

Mobilome impacts on physiology in the widely used non-toxic mutant Microcystis aeruginosa PCC 7806 ΔmcyB and toxic wildtype [PDF]

BMC Genomics
The Microcystis mobilome is a well-known but understudied component of this bloom-forming cyanobacterium. Through genomic and transcriptomic comparisons, we found five families of transposases that altered the expression of genes in the well-studied ...

Synergy Effect of Environmental Factors on the Growth and Toxins Production by Microcystis aeruginosa [PDF]

Nature Environment and Pollution Technology, 2021
Microcystis is one of the most common algal genera that causes water eutrophication. The effect of water quality on the growth and toxins production of Microcystis has been attracting high research attentions.
