Anaerobic microbial dissolution of lead and production of organic acids

Patent ·
OSTI ID:6803310
; ; ;
A method of solubilizing lead oxide in industrial wastes and producing soluble Pb/sup 2+/ which is described comprises dissolving the lead oxide by contacting the wastes with an anaerobic bacterial culture containing Clostridium sp. ATCC No. 53464 before the wastes are dumped into the environment, and removing the solubilized lead from the wastes by chemical separation and bioaccumulation.
