利用介电谱(DS)技术研究了Cu 2+溶液对铜绿微囊藻(Microcystis aeruginosa)的毒性。发现0.04 mM Cu 2+对介电增量没有影响,而高于0.1 mM的Cu 2+浓度降低Δ ε/Δ ε的值。Cu ~(2+)对M.铜绿假单胞菌细胞凋亡呈时间依赖性和浓度依赖性。在0.04 ~ 0.1 mM之间存在一个阈值浓度,表明Cu ~(2+)在高于0.1 mM时对M.铜绿假单胞菌加入1 mM Ca ~(2+)或Mg ~(2+)对M无保护作用。铜绿假单胞菌细胞从ImM Cu 2+毒性。该研究表明,DS监测细胞生物量,便于观察金属离子的毒性作用。
Dielectric spectroscopy (DS) was utilized to investigate the toxicity of the Cu2+ solution to Microcystis aeruginosa. It was found that 0.04 mM Cu2+ had no effect on dielectric increment, whereas the Cu2+ concentrations above 0.1 mM decreased the value of Δɛ/Δɛintact. The toxic effect of Cu2+ on M. aeruginosa cells was time-dependent and concentration-dependent. There was a threshold concentration between 0.04 mM and 0.1 mM, which affected the cell membrane, suggesting that Cu2+ at the concentrations higher than 0.1 mM caused serious plasmalemma damage to M. aeruginosa cells. The addition of 1 mM Ca2+ or Mg2+ did not protect M. aeruginosa cells from 1 mM Cu2+ toxicity. The study demonstrates that DS monitors cell biomass facilitating observation of the toxic effects of metal ions.
