Phosphorus enrichment and carbon depletion contribute to high Microcystis biomass and microcystin concentrations in Ugandan lakes
Phosphorus enrichment carbon depletion contribute
2014/4/2
We investigated the factors influencing cyanobacterial biomass and microcystin (MC) concentrations in several
Ugandan lakes from September 2008 to February 2009. We characterized thermal structure, l...
Studies on Extracting Microcystin-Lr from Microcystis Aeruginosa by Water Bath
Boiling Water Bath Extract Microcystin-LR
2013/3/9
Different temperatures of water bath was used to extract the intracellular microcystin-LR(MC-LR) of Microcystis aeruginosa. Researching the extraction efficiency under the suitable temperature, so tha...
The Effects of Sample Matrices on Immunoassays to Detect Microcystin-LR in Water
Microcystin Immunoassay Sample Matrix Natural Organic Matter
2013/3/12
Immunoassays are widely used biochemical techniques to detect microcystins in environmental samples. The use of immunoassays for the detection of microcystins is vulnerable to matrix components and ot...
微囊藻毒素Microcystin-LR体外遗传毒性
微囊藻毒素 微核 突变 TK6细胞
2008/9/17
背景与目的： 应用人类淋巴母细胞TK6研究微囊藻毒素 (Microcystin-LR,MCLR)的体外遗传毒性。 材料与方法： MCLR体外染毒TK6细胞4 h或24 h后检测细胞毒性、微核及tk位点突变频率。 结果： 4 h染毒未引发明显细胞毒性，24 h MCLR染毒导致TK6细胞相对存活率下降，细胞微核率及TK基因突变频率明显上升，并有剂量－反应关系。最高浓度组(80 μg/ml)的细胞微核...
Changes in microcystin production in cyanobacteria exposed to zooplankton at different population densities and infochemical concentrations
microcystin production cyanobacteria exposed to zooplankton different population densities infochemical concentrations
2014/4/22
We investigated microcystin (MC) production by four cyanobacterial strains (three Microcystis aeruginosa and one Planktothrix agardhii) in response to different grazer densities (direct exposure: zero...
A direct test of cyanobacterial chemical defense: Variable effects of microcystin-treated food on two Daphnia pulicaria clones
cyanobacterial chemical defense microcystin-treated food two Daphnia pulicaria clones
2014/4/22
To determine the direct effects of microcystin on the fitness of herbivorous zooplankton, we experimentally added microcystin-LR to freeze-dried cells of palatable Chlorella and fed these compound-tre...
Effects of Microcystis aeruginosa and purified microcystin-LR on the feeding behavior of Daphnia pulicaria
Effects of Microcystis aeruginosa purified microcystin-LR feeding behavior Daphnia pulicaria
2014/5/14
We investigated the mechanisms behind the negative effects of cyanobacteria on zooplankton by comparing the effects of Microcystis aeruginosa single cells, colonies, and toxins on the feeding behavior...
Daphnia growth on microcystin-producing and microcystin-free Microcystis aeruginosa in different mixtures with the green alga Scenedesmus obliquus
Daphnia growth microcystin-producing microcystin-free Microcystis aeruginosa green alga Scenedesmus obliquus
2014/5/22
The hypothesis that negative effects of Microcystis on Daphnia growth and reproduction can be explained from the presence of microcystin in the Microcystis cells was tested by comparing the effects on...
