  • Bacteria can be used for mining minerals in space.

    Can Bacteria Mine Minerals In Space? On the Earth, bacteria play a vital role in getting the minerals from the ground. They are responsible for the natural weathering of rocks and thereby, the release of minerals stored in them. This ability of the bacteria to retrieve metals has been used in human mining activities. It a called as 'biomining
