Effects of terrestrial dissolved organic matter on the growth, photosynthesis and colonial morphology of Microcystis aeruginosa at different levels of iron

Ecotoxicology and Environmental Safety
Terrestrial dissolved organic matter (tDOM) holds great promise for controlling cyanobacteria blooms through watershed management. To identify tDOM that could inhibit the growth, photosynthesis and colony formation, unicellular Microcystis aeruginosa ...

Simulated microgravity alters growth and microcystin production in Microcystis aeruginosa (cyanophyta)

, 2010
Recent researches indicated that microgravity can increase pathogenic bacteria virulence. We presumed that microgravity might affect the toxin production of toxic cyanobacteria too.

Elucidating the toxicity targets of beta-ionone on photosynthetic system of Microcystis aeruginosa NIES-843 (Cyanobacteria)

, 2011
In order to explore the potential targets of toxicity of beta-ionone on the photosynthetic system of Microcystis aeruginosa, the polyphasic rise in chlorophyll a (Chl a) fluorescence transient and transcript expression for key genes in photosystem II ...

Involvement of nitric oxide in the mechanism of biochemical alterations induced by simulated microgravity in Microcystis aeruginosa

, 2012
Simulated microgravity (SMG) can inhibit proliferation and enhance microcystin production of Microcystis aeruginosa. We investigated the role of nitric oxide (NO) in regulating the SMG induced changes of proliferation, photochemical system II ...

Homeostatic response of calcium and potassium ions in Microcystis spp. and Chlorella to MC-LR

Ecotoxicology and Environmental Safety
Cyanobacteria and green microalgae often co-exist during toxic algal blooms, but the influence of microcystins (MCs) on ionic homeostasis of these algae is not well-studied.

Correlations Between a Cyanobacteria Bloom's Decline and Environmental Dynamics. [PDF]

, 2009
Lake Kainui is an ombrogenous peat lake that is eutrophic and has frequent cyanobacterial blooms. This research aimed to elucidate the factors that correlated with cyanobacterial bloom decline in Lake Kainui. Abiotic and biotic variables in Lake Kainui

Leucine incorporation by Microcystis aeruginosa

, 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.

Enhancement of planktonic rotifers by Microcystis aeruginosa blooms: An enclosure experiment in a shallow eutrophic lake

, 2002
Enclosure experiments with three treatments (sediment addition, sediment + nitrogen enrichment, sediment + phosphorus enrichment) and unfertilized controls were performed in shallow hypereutrophic Lake Donghu during the summer of 2000.

Towards clarification of the inhibitory mechanism of wheat bran leachate on Microcystis aeruginosa NIES-843 (cyanobacteria): physiological responses

, 2010
Wheat bran leachate (WBL) has been shown to have an inhibitory effect on Microcystis aeruginosa in this study. In order to explore the inhibitory mechanism of WBL on M. aeruginosa, physiological responses of M.
