The Range of the Colonial Microcystis’ Biomass for Shift to Diatom Aggregates Under Aeration Mixing and Low Light

Diversity
In order to investigate non-cyanobacteria dominance succession from Microcystis blooms, particularly to diatom dominance, an experiment using varying colonial Microcystis biomasses expressed as bulk concentrations of 2.0, 4.0, 6.0, 8.0, 10.0, 12.0, 14.0,

Effects of iron on growth, pigment content, photosystem II efficiency, and siderophores production of Microcystis aeruginosa and Microcystis wesenbergii [PDF]

, 2007
Changes in growth, photosynthetic pigments, and photosystem II (PS II) photochemical efficiency as well as production of siderophores of Microcystis aeruginosa and Microcystis wesenbergii were determined in this experiment.

Aerobic anoxygenic phototrophs play important roles in nutrient cycling within cyanobacterial Microcystis bloom microbiomes

Microbiome
Background During the bloom season, the colonial cyanobacterium Microcystis forms complex aggregates which include a diverse microbiome within an exopolymer matrix.

Dynamics of Microcystis surface scum formation under different wind conditions: the role of hydrodynamic processes at the air-water interface

Frontiers in Plant Science
Due to climate change, Microcystis blooms occur at increasing frequencies in aquatic ecosystems worldwide. Wind-generated turbulence is a crucial environmental stressor that can vertically disperse the Microcystis surface scum, reducing its light ...

Three newly recorded species of Microcystis (Cyanophyta) from China

, 2007
About 50 species of Microcystis so far have been reported in the world, and 19 species were described in China. During our recent investigations for water-bloom forming blue-green algae in China, a diverse group of Microcystis species occurring in some ...

Performance and characterization of snail adhesive mucus as a bioflocculant against toxic Microcystis

Ecotoxicology and Environmental Safety
Toxic Microcystis blooms are widespread in aquatic bodies, posing major threats to aquatic and human life. Recently, bioflocculants have attracted considerable attention as a promising biomaterial for Microcystis management. In search of a novel organism

Identification of toxic and non-toxic Microcystis by three primers

, 2004
To discriminate from toxic and non-toxic Microcystis, 3 pairs of primers epF/mb1R, mcF/teR and mcF/umR were designed, based on sequences of microcystin synthetase gene cluster.

Colonial Microcystis’ biomass affects its shift to diatom aggregates under aeration mixing

Scientific Reports
The effect of hydrodynamic mixing on controlling Microcystis blooms or changing the algal community to diatom dominance has been widely studied; however, the effects of colonial Microcystis biomass on the development of the algal community are poorly ...

COMPARISON BETWEEN THE TOXIC MICROCYTIS SPECIES AND NON-TOXIC MICROCYSTIS SPECIES ORIGINATED FROM THE COCULTURE OF MICROCYSTIS AND POTERIOOCHROMOAS SP.

, 2009
Predation of Poterioochromonas sp. on prey Microcystis is normally a one way process, i.e., prey cells were continuously ingested and gradually disappeared. However, it was not always the same.

Inhibition of the predatory activity of the copepod Mesocyclops notius by Microcystis spp.

, 2004
The feeding rate of the copepod Mesocyclops notius on two species of cladocerans (Daphnia carinata and Ceriodaphnia cornuta) decreased with increasing environmental concentration of 64-122 mum colonial Microcystis spp.
