Potential of plants and microorganisms for bioremediation technologies for mine rehabilitation

pollution by potentially toxic metals. The impact on the environment
remains significant even after the end of mining activities. Numerous
studies report the environmental impact of abandoned mines.
Therefore, cleaning of mine territories from the pollution is of
priority importance. Phytoremediation and microbial remediation are
some of the methods. The study of plants for their possible use in
phytoremediation is of great interest. Such works are of great
importance in developing modern phytoremediation technologies, as
they allow us to find new hyperaccumulators for possible mine
reclamation.
Microorganisms possessing resistance to heavy metals, such as fungi
and bacteria, as well as unicellular algae, may be used to clean up
tailings contaminated with potentially toxic metals. The
microbiological method of tailings treatment is based on the ability
of microorganisms to transform and decompose chemical
compounds.
Microbial remediation and phytoremediation are attracting more and
more attention due to their relatively low cost and environmental
friendliness. A large number of studies related to the investigation of
mine plants and microorganisms and their utilization for mine
cleanup demonstrate the promise of using bioremediation. Further
development of bioremediation technologies will be associated with
wider implementation of the research findings in practice and the
possible use of biotechnology in bioremediation.
The successful practical application of mine bioremediation requires
a complex interdisciplinary approach associated with biological,
ecological, biotechnological, and geographic-geological areas.
