The mosaic structure of the mcyABC operon in Microcystis [PDF]
Microbiology, 2008 An extensive study of the mcyABC genes and regions flanking the mcy gene cluster was performed in naturally occurring Microcystis strains. Lack of methylation in strains producing only desmethyl(7)-microcystin was found to be associated with point mutations in substrate-binding sequence motifs of the N-methyltransferase (NMT) domain in McyA.

Coordinated Diel Gene Expression of Cyanobacteria and Their Microbiome
Microorganisms, 2021 Diel rhythms have been well recognized in cyanobacterial metabolisms. However, whether this programmed activity of cyanobacteria could elicit coordinated diel gene expressions in microorganisms (microbiome) that co-occur with cyanobacteria and how such ...

Toxic concentrations of metronidazole to Microcystis protocystis [PDF]
Brazilian Journal of Biology, 2014 Antimicrobials are among the most commonly used drugs and have become a class of contaminants with great environmental importance. Metronidazole is an antimicrobial used for the therapeutic management of several human diseases. The toxicity of antimicrobials on aquatic species may affect sensitive microorganisms and reduce metabolic processes ...

Journal of Freshwater Ecology, 2019 We investigated how the N:P ratio can shape the structure of picophytoplankton and Microcystis, which are abundant and widespread in eutrophic lakes. Unialgal culture and coculture batch experiments were conducted to study the growth and interspecific ...

Colony formation in the cyanobacterium Microcystis [PDF]
Biological Reviews, 2018 ABSTRACTMorphological evolution from a unicellular to multicellular state provides greater opportunities for organisms to attain larger and more complex living forms. As the most common freshwater cyanobacterial genus, Microcystis is a unicellular microorganism, with high phenotypic plasticity, which forms colonies and blooms in lakes and reservoirs ...

Use of a generalized additive model to investigate key abiotic factors affecting microcystin cellular quotas in heavy bloom areas of Lake Taihu. [PDF]
PLoS ONE, 2012 Lake Taihu is the third largest freshwater lake in China and is suffering from serious cyanobacterial blooms with the associated drinking water contamination by microcystin (MC) for millions of citizens.

Lipopolysaccharides of the cyanobacterium Microcystis aeruginosa [PDF]
European Journal of Biochemistry, 1983 Lipopolysaccharides (LPS) of two isolates of Microcystis aeruginosa were extracted with phenol/water and purified. Cesium chloride gradient ultracentrifugation of these preparations yielded only one fraction. The LPS contained significant amounts of 3‐deoxy‐d‐manno‐octulosonic acid, glucose, 3‐deoxy sugars, glucosamine, fatty acids, fatty acid esters ...
