Role of microorganisms in rehabilitation of mining sites ...

These natural capacities can be exploited for the bioremediation of mine impacted sites. Microorganisms also play a key role in phytostabilisation, either indirectly by promoting plant growth or directly through metals and metalloids mobilization or immobilization in soils. Thus, microorganisms are important actors of mining sites remediation.

21 Major Beneficial Activities of Bacteria

ADVERTISEMENTS: Some of the major beneficial activities of bacteria are as follows: Role in Nature: 1. Nature's Scavengers: Bacteria decompose organic matter, by decay and putrefaction, to keep our earth clean. Decay is the aerobic decomposition of organic matter without the release of foul smell, while putrefaction is the anaerobic decomposition of organic compounds with [.]

Biomining - Wikipedia

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
