| 英文摘要 | ［中文文摘］研究了在低营养含汞环境中,高选择性汞富集基因工程菌E.coliJM109(表达MerT、MerP汞特异结合转运蛋白和金属硫蛋白MT,该菌简称为M1)的生长富集耦合行为.考察了汞离子浓度、离子强度、络合物、共存金属离子等环境因素对其生长富集Hg2+耦合行为的影响;并且利用连续操作搅拌槽式生物反应器,实现了对有机废水配伍的含汞废水的连续化处理.［英文文摘］Genetically engineered E.coli JM109,namely M1,which expressed both Hg~2+ transport system and metallothionein,was tested for its capability of simultaneous growth and bioaccumulation of Hg~2+ (SG&B) under low nutritional circumstances.The influential factors of ambient conditions,e.g.initial concentrations of mercuric ion,ionic strength, the presence of metal chelators and other coexisting metal ions were investigated.Hg~2+ bioaccumulation behavior of M1 was proved to be well coupled with its growth of M1.Furthermore ,continuoust reatment of Hg2 + contaminated organic wastewater was realized via continuous stirred2tank bioreactor.; 教育部优秀青年教师资助计划项目; 福建省自然科学基金(D0310004). |
