15 صفحه اولCombined effects of two antibiotic contaminants on Microcystis aeruginosa.
Combined toxicity of spiramycin and amoxicillin was tested in Microcystis aeruginosa. The respective 50% effective concentrations (EC50mix) expressed in toxic unit (TU) values were 1.25 and 1.83 for spiramycin and amoxicillin mixed at 1:7 and 1:1, suggesting an antagonistic interaction at the median effect level. Deviations from the prediction of concentration addition (CA) and independent acti...
متن کاملEffects of Dihydroartemisinin and Artemether on the Growth, Chlorophyll Fluorescence, and Extracellular Alkaline Phosphatase Activity of the Cyanobacterium Microcystis aeruginosa
Increased eutrophication in the recent years has resulted in considerable research focus on identification of methods for preventing cyanobacterial blooms that are rapid and efficient. The objectives of this study were to investigate the effects of dihydroartemisinin and artemether on the growth of Microcystis aeruginosa and to elucidate its mode of action. Variations in cell density, chlorophy...

Phenolic Compounds Exuded from Two Submerged Freshwater Macrophytes and Their Allelopathic Effects on Microcystis aeruginosa
Culture solutions of the submerged freshwater macrophytes Hydrilla verticillata and Vallisneria spiralis, separately incubated at 10 g of fresh weight (FW) per liter for three days, were extracted by solid phase extraction (SPE) followed by liquid liquid extraction (LLE), and the acquired ethyl acetate fractions were analyzed by gas chromatograph-mass spectrometry (GC-MS) to identify potential ...
