Abstract:
A bacterial strain DN25, effective on cyanide-degradation, was isolated from contaminated soil and identified as Alcaligenes sp. on the basis of phenotype analysis and 16S rDNA sequence analysis. It showed great tolerance to the cyanide, which can grow in the medium containing 500mg CN -/L. The suitable condition for the cell growth and boitransformation was pH8.0 and 30oC and the transformation rate for 500mg CN - /L could achieve 99% in 10 h. It has also been found that the screened strain had the ability of K 4Fe(CN) 6 transformation with 96% of transformation rate at 12 h for the concentration of 500 mg CN /L.
