The study showed that the biosorption process could be described well by pseudo-second-order kinetic model and Freundlich isotherm model.Higher cell concentration was favorable to the biosorption.Temperature's effect on the biosorption was not obvious.The oxygenous and nitrogenous functional groups on the cell wall played a very important role in the process of biosorption.Microdeposits were formed by int...

结果表明，菌体对银的吸附量可达91.75 mg/g，吸附过程符合Pseudo-second Order吸附动力学模型，相关系数高达0.999 9；吸附热力学很好地符合Freundlich吸附等温模型，相关系数为0.99；考察菌体浓度和温度对吸附的影响发现，菌体浓度增加有利于对银离子的吸附，温度对吸附影响较小；FTIR、SEM及EDAX实验结果表明吸附存在2种吸附机理，一为菌体表面一些含氮氧的基团对Ag+的络合作用，二为菌体分泌的胞外多糖等物质对Ag+的微沉淀成晶作用。

This experiment aimed to systematically investigate and analyze the ethanol activated rates of mouse oocytes, affected factors of oocytes activation, types and development of parthenotes, and the organization and roles of the cytoskeleton during pronuclear formation and migration and early embryo cleavage by ethanol activation of oocytes, embryo culture in vitro and immunofluorescence cyto-chemistry. The results:(1) The ethanol activation of mouse oocytes showed that the activated and developmental rates of oocytes increased significantly with the increase of ethanol concentration and extension of exposure time, but over concentration and exposure time would result in increased fragment rates significantly. 7% ethanol treated oocytes for 7min was the optimum activated condition.
