Manganese is a versatile element, a common component in several alloys' fabrication. For example, zinc alloys and magnesium alloys contain Mn, but also, we can find this element in gold, silver and bismuth production. Nevertheless, in some cases the quantities involved are very small.
Batch culture experiments showed that manganese could be leached from a manganese-containing silver ore by bacterial strain SSW 22, by a mixed culture derived from unsterilized ore, and by a Penicillium strain isolated from the mixed culture. The extent of leaching was influenced by the kinds of electrolytes and their concentration in the culture medium.
