Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition. [PDF]

Environ Microbiol Rep
ABSTRACT Microcystis aeruginosa is a toxic cyanobacteria species that is often abundant during cyanobacterial harmful algal blooms (cyanoHABs) in freshwaters. This study examined how growth on different nitrogen substrates influences the exometabolome of toxic and non‐toxic strains of

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.

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

Morchella Effectively Removes Microcystins Produced by Microcystis aeruginosa. [PDF]

Microbes Environ
Microcystins (MCs) produced by Microcystis aeruginosa are harmful to animal and human health, and there is currently no effective method for their removal. Therefore, the development of biological approaches that inhibit cyanobacteria and remove MCs is needed.

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 ...

Light limitation inducing overcompensatory growth of cyanobacteria and function of serine/threonine kinase (STK) genes involved

Water Science and Technology, 2021
The rapid overcompensatory growth that appears when cyanobacteria are supplied with adequate resources after a period of resource deprivation might contribute to the occurrence of cyanobacterial blooms.

Leucine incorporation by Microcystis aeruginosa [PDF]

Limnology and Oceanography, 2000
In experiments with axenic cultures of Microcystis aeruginosa, we tested whether this cyanobacterium incorporates leucine, a compound that is often used for the measurement of heterotrophic bacterioplankton production. Microcystis showed significant leucine incorporation, and the uptake of exponentially growing cells was higher than the uptake of cells
