Title:
METHOD OF REDUCTION OF ARSENIC ACID TO ARSENIOUS ACID AND METHOD OF CLEANING ARSENIC CONTAMINATED SOIL USING THE SAME
Document Type and Number:
Japanese Patent JP2004305213
Kind Code:
A
Abstract:

To provide a method for inexpensively and easily eliminating arsenic in the soil contaminated by arsenic.

Bacillus spp. SF-1 strain (FERM P-15431) can reduce arsenic acid to arsenious acid and solubilize the arsenic. A bioremediation process for the soil contaminated by arsenic is constructed by using the strain, and the arsenic is easily eliminated in low cost. The SF-1 strain changes the arsenic acid into soluble arsenious acid therefore the soil contaminated by arsenic can be washed by water and the concentration of the arsenic is decreased.
