ABSTRACT:
Disclosed is an efficient biological process for recovering heavy metals from refractory manganiferous ore, and a process for removing heavy metal contaminants from the soil. The process utilizes manganese reducing Bacillus sp. Specifically exemplified is a novel microbe designated Bacillus MBX 69, or mutants thereof, and the known microbe Bacillus polymyxa, which is disclosed in U.S. Pat. No. 5,055,130. Further, gene(s) encoding the enzyme(s) obtainable from the said bacteria can be used by placing such gene(s) on a suitable vector and transforming a competent host. The transformed host then can be used in the same manner as the native microbe. Also, the enzyme(s) themselves can be used in the above-described processes.
