Effect of Coal Mining on Soil Microorganisms from

The response strategy of soil fungi to coal mining and the stability of arbuscular mycorrhizal fungi (AMF) in the soil fungal community were determined. Our results showed that coal mining affected AMF and Microorganisms play a key role in biogeochemical cycles controlling metals and metalloids fate and behavior in polluted environments. Some microorganisms Role of microorganisms in rehabilitation of mining sites,

Coal mining activities produce coal mine drainage which becomes a potential pollutant of regional groundwater. The temperature and microbial community in aquifers and rock The samples of raw coal and mine water were from the coal seam, indicating that the microorganisms in the coal slurry are from the coal seam and enter Sources and succession of microorganisms in industrial coal

Unveiling the crucial role of soil microorganisms in carbon

Study on the factors of hydrogen sulfide production from

1 天前Bacterial sulfate reduction (BSR) is one of the key factors leading to the anomalous accumulation of hydrogen sulphide in coal mines. Environmental factors such as Coal mines offer habits for a large diversity of microorganism. These microbes play an essential role in many geochemical cycles around coal mine, such as sulfur and carbon Microorganisms Special Issue : Microorganisms around Coal

Microbiome of highly polluted coal mine drainage from

1 Altmetric Metrics Abstract Drains from coal mines remain a worrisome point-source of toxic metal/metalloid pollutions to the surface- and ground-waters Such relationships had already been revealed in research conducted on semi-natural alpine meadows 26 as well as on other post-industrial lands such as those on brown coal spoil heaps 1, 23, 29, 34, 75, 76, and surface coal mining sites 29, 77. To our knowledge no such detailed investigation has been previously conducted on spoil heaps The role of plants and soil properties in the enzyme activities

The relationships between heavy metals and bacterial

Coal plays an important role in the development of the national economy (Xiao et al., 2019; Zhang et al., 2018), and it continues to dominate the field of energy consumption (Chen et al., 2020a; Vick et al., 2019). Coal gangue is a solid waste by-product that is generated during the process of coal mining, transportation, washing, and The environmental changes caused by coal mining activities caused disturbances to the plant, soil, and microbial health in the mining area. Arbuscular mycorrhizal fungi (AMF) play an important role Effect of Coal Mining on Soil Microorganisms from

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 Soil is the main limiting factor that affects the restoration of degraded ecosystems in coal mining areas (Du et al. 2009; Yin et al. 2010).Soil microorganisms, such as bacteria, participate in the decomposition of organic matter, growth of plants, and other critical ecological processes (Lu et al. 2022).The influence of the microenvironment is Diversity of soil bacteria in alpine coal slag mountain

Fertilizer management methods affect bacterial community

The filling or mixed stack mode is a frequently used coal mine reclamation engineering technique that results in changes in soil microbial community structure and nutrient content, which lead to considerable deviations from the characteristics of restored coal mine reclamation areas that can be used for farming. Fertilization is an effective Acidophiles are ecologically and economically important groups of microorganisms that thrive in acidic natural habitats, like solfataric fields, sulfuric pools, sulfur springs, marine volcanic vents, and man-made acidic environments such as acid mine drainage (AMD) or acid rock drainage (ARD), mining of coal and metal ores, having Acidophilic Microorganisms SpringerLink

Phosphate solubilizing microorganisms as a driving force to assist mine

Phosphate solubilizing microorganisms (PSMs) are a group of beneficial microorganisms that mediate soil phosphorus cycling and biological utilization. The primary function of these micoorganisms is to release phosphorus from insoluble phosphorus compounds to promote the utilization of P by plants (Chen et al. 2019).PSM category is Soil microorganisms play vital roles in ecosystem functions, and soil microbial communities might be affected by heavy metal contamination caused by the anthropogenic activities associated with the coal-based industry.

Different fertilization treatments in coal mining-affected soils

Purpose Coal mining activities result in large-scale soil degradation and ecosystem imbalances in many countries. Fertilization is an effective way to improve soil fertility and microbial activity. However, the effect of different fertilizers and remediation time on the subsided soil is not clear. The aim of this study is to explore the effects on soil The paper deals with the nature of mine drainage in the North Eastern Coalfield, Margarita, Assam (India). The drainages from the Margerita group of mines are found to be acidic with high sulphate ranging up to 1500 ppm and iron content rising up to 40 ppm. The total sulphur in coals is up to 7% out of which 50–80% is non-reactive organically found sulphur. The The role of micro-organisms in the formation of acid mine

Microbial remediation technology has engrossed rapid attention in the field of environmental research (Das et al. 2014; Das and Singh 2011; Ghosh and Das 2015 ). Microorganisms play a significant 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.

Since plants take up the nutrients as well as heavy metals along with water from soil, the bioavailability of heavy metals is determined at large by the indigenous microbial communities.

Silicified Microorganisms and Microorganism-Like Particles

Relatively little research has been conducted on the preservation of microorganisms and microbial particles in the groundwater of abandoned mines (GAM). In this study, silicified microorganism-like particles, 50–450 nm in diameter, were found to commonly occur outside microbes and their associated extracellular polymers. These Microbes are playing increasingly important roles in commercial mining operations, where they are being used in the "bioleaching" of copper, uranium, and gold ores. Direct leaching is when microbial© 1995 Nature Publishing Group

Sources and succession of microorganisms in industrial coal

1. Introduction. Coal flotation can recover coal (<0.5 mm) and increase economic efficiency based on differences in surface properties between coal and inorganic minerals [1], [2].The flotation reagents play a significant role in the flotation process [3], [4].Some studies have pointed out that microorganisms or extracellular polymeric One of the soil functions is supplying plants with nutrients; microbiome plays a considerable role in this function by transforming nutrients (first and foremost, nitrogen and phosphorus compounds) into the form available for plants [].Microorganisms transform nitrogen-containing substances by nitrogen fixation, ammonification, Microbiological Indicators of Soil Ecological Functions: A

The impact of indigenous microorganisms on coal flotation:

Therefore, coal preparation plants increase the ratio of circulating water in process water [10], [11], the ratio may be up to 90 % in some areas [7]. So the water management of coal preparation plants needs more attention. Raw coal contains a large number of microorganisms, generally 10 4-10 5 cells/ml in coalbed [12], [13]. In flotation
