The influence of Ni~(2+),Cd~(2+) and Cu~(2+) on electron transport system(ETS) activity of anaerobic 2-chlorophenon degradation sludge,as well as the effect of acclimation on microbial resistance to metallic toxicity,was investigated.

• 以2-氯酚(2-CP)厌氧降解污泥电子传递体系(ETS)活性为考察对象；研究了3种典型重金属元素Cu2+、Cd2+、Ni2+对ETS活性的影响；并比较了驯化过程对提高厌氧微生物抗重金属毒性的作用.
