ABSTRACT:
Disclosed is an efficient biological process for recovering silver and manganese from refractory manganiferous silver ore. The process utilizes manganese reducing Bacillus sp. Specifically exemplified is a novel microbe designated Bacillus MBX 69, or mutants thereol 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 to recover silver and manganese from refractory manganiferous silver ore.
