[Objective]The aim was to screen out strain with high tolerance to cadium,to provide theoretical basis for remediation technology of heavy metal contaminated microorganism. [Method]With DN-1 and DN-2 as tested strains,under different conditions of culture time,temperature,pH,initial concentration of Cd~(2 +)solution,the effect of different strains on the adsorption of Cd~(2 +)was studied. [Result]The results showed that under certain experimental conditions,when cultured for three days the adsorption rate o...
