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.
Restoration of ecosystem functions is one of the primary objectives of mine restoration. Microorganisms can help with the restoration of ecosystem functions and play an important role in mine restoration (Jiao et al., 2022).Microbial communities have been shown to promote plant community restoration by affecting ecosystem functions such as element cycling …
Literature on the use of microbial inoculants to increase crop yields, to control soil-borne plant diseases, or to degrade pollutants has been reviewed. Established inoculant technology based on Rhizobium/peat inoculants has been summarized. Special emphasis has been placed on the use of carrier materials for the delivery of microbial inoculants. Some new developments, e.g., the …
Johnson and Hallberg divide the remediation approaches in two categories: (a) abiotic systems where a chemical agent is used to neutralize the AMD and (b) biological …
It was generally believed that coal sources are not favorable as live-in habitats for microorganisms due to their recalcitrant chemical nature and negligible decomposition. However, accumulating evidence has revealed the presence of diverse microbial groups in coal environments and their significant metabolic role in coal biogeochemical dynamics and …
The microorganisms can act like natural biocontrol agents that help to suppress plant diseases caused by pathogens. The beneficial microbes colonize plant surfaces like the rhizosphere (the soil around the plant root), compete with harmful organisms for resources, and produce antimicrobial compounds or induce systemic resistance in plants ...
Owing to their roles in the arsenic (As) biogeochemical cycle, microorganisms and plants offer significant potential for developing innovative biotechnological applications able to remediate As pollutions. This possible use in bioremediation processes and phytomanagement is based on their ability to catalyse various biotransformation reactions leading to, e.g. the …
produce cheese, yoghurt, kefir and kimchi. Acetic acid bacteria (AAB) is used in traditional manufacturing of vinegar. Bacteria are used to create multiple antibiotics such as streptomycin from the bacteria streptococcus. Another important role in pharmaceuticals is the use of microbes for the medically important studies, such as bacteriorhodopsin.
Restoration of ecosystem functions is one of the primary objectives of mine restoration. Microorganisms can help with the restoration of ecosystem functions and play an …
The responsible use of indigenous microorganisms to get economic, ... concerned companies and local authorities have demonstrated interest in managing water from metallurgical and mining areas. After processing of mineral ores in metallurgical industries, the residual metals in effluent water would cause a substantial loss in revenue for ...
Rapid depletion of the world's mineral deposits combined with the expanding demand for metals places great pressure on our ability to provide technologically and economically feasible processes to recover greater amounts of metals from progressively lower grade sources. Chemical mining is one area in which expanding research and development can provide new …
In biosurfactants, almost all microorganisms are external microorganisms. In fact, the flotation system contains internal microorganisms. Päivi Kinnunen pointed out that microorganisms could be introduced into the flotation system from the intake water and ore material [17].During the coal flotation process, raw coal in the coal seams is used as the …
This chapter provides a detailed overview of microbial remediation technologies specifically tailored to mining and industrial waste. It explores the diversity of microorganisms capable …
Land use change is among the global challenges that pose a serious threat to biodiversity loss (Winkler et al., 2021).Changes in land use are the manifestations of how human inference affects the Earth's natural system and contributes significantly to global environmental change (Lawler et al., 2014).For example, in China, the most common land use change …

Generally speaking, biotechnology involves the use of processes that are facilitated by cells or their components to achieve a specific end-goal. For the mining sector, biotechnologies have been proposed or established for a …
The present review was based on publications that attend at least one of the following criteria: (1) use of microorganism with capacity to induce CaCO 3 precipitation; (2) analysis of the capacity to precipitate calcite; (3) use of different strategies for the application of microorganisms to concrete or mortar – encapsulated, impregnated in ...
These bacteria utilize oxidoreductive enzymes for dye degradation. Aerobic bacteria use oxygen-catalyzed azoreductase to break the azo bonds . Some bacterial strains degrade dyes in aerobic conditions and use mono and dioxygenase for oxidizing the aromatic ring of organic compounds . Anaerobic bacteria use the enzyme azoreductase to degrade azo ...
Traditional methods of biobutanol and bioethanol production involve the use of a chemical process supplemented with the use of mesophilic microorganisms such as Saccharomyces cerevisiae and Clostridium species 27. ... In addition to biofuels, another important application of extremophiles and their enzymes can be found in the mining sector 40.
This process, called bioleaching, involves the use of bacteria and archaea that can dissolve and extract metals from low-grade ore. The microorganisms used in bioleaching can tolerate high levels of heavy metals and acidity, making them well-suited for use in mining operations.
While the exact biochemical and molecular mechanisms involved in coal biodegradation under ambient conditions remain to be better elucidated, there certainly appears to be a contribution of microbial solubilization, oxidation, and liquefaction [5,93] that demonstrate the potential to use microorganisms in effective rehabilitation strategies.
1. Introduction. Arsenic (As) is a highly toxic element among aquatic environments, especially in its inorganic form (Preetha et al., 2023).Arsenic-containing acid mine drainage is generated by the oxidation of abandoned sulfide-enriched arsenopyrite rocks, a most prevalent byproduct of coal mining, typically with a total arsenic concentration over 20 mg·L −1 (Laha et …

Introduction. Arsenic (As), which is often considered a non-essential element except for some organisms (but would be in fact an ultratrace element) and classified as a carcinogen, is a common contaminant of water, soil and food, and a global danger to human health (Nordstrom 2002; Zhao et al. 2010; ATSDR 2017; Marchant et al. 2017; da Silva et al. 2018a).
Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
