“…Particularly organic matter and Humic + Fulvic Acid contained in coal or coal waste contribute to soil quality and plant growth. Obtaining better results in the prepared mixtures than the reference mixture is due to this organic matter and Humic + Fulvic Acid in the coal content (Song and Lee, 2010;Peña et al, 2015;Ultra et al, 2022;Bai et al, 2023;Feng et al, 2023;Jayapal et al, 2023;Yin et al, 2023).…”

“…It was determined that heavy metal values of all mixtures were below the heavy metal limit values allowed in the soil. Thus, it was understood that heavy metals in the content of the waste would not cause harm to human health, as in similar studies using different mine waste (Chen et al, 2019;Samsuri et al, 2019;Esteves-Aguilar et al, 2023;Jayapal et al, 2023;Nassiri et al, 2023;Tibane and Mamba, 2023;Zhang et al, 2023).…”

In this study, the usability of the mixtures consisting of lignite coal taken from Tekirdag region and marble and travertine wastes taken from the marble factory in Gumushane region in local bean (Kelkit) cultivation was researched. First, control samples were created using only humus soil without coal, marble, or travertine dust. Then, for each coal or coal waste, coal/coal waste—waste marble dust and coal/coal waste—travertine dust mixtures were formed. These mixtures were obtained by mixing 25%, 50%, 75%, and 100% by weight of coal and 25%, 50%, and 75% by weight of marble and travertine dust. Afterwards, local beans were planted in these mixtures and their development was followed under laboratory conditions. Additionally, temperature and humidity values were recorded at certain intervals, pH and heavy metal analysis measurements were made on the mixtures before and after bean planting, the height and leaf measurement of the beans grown and the number of beans grown in these beans were also followed, and chlorophyll analysis was performed on the bean plants grown in these mixtures. As a result, 50% Coal-3D + 50% Travertine mixture had the maximum length increase, that 25% Coal Waste (Powder)-K3 + 75% Marble mixture had the highest number of beans, and that 50% Coal Waste -AK + 50% Marble mixture had the maximum leaf formation. In these mixtures, maximum 12 beans were grown and maximum 93 leaves were formed. Also, the bean plant was grown in all mixtures. The chlorophyll contents were at least as much as the values of the beans grown only in soil. However, heavy metal values do not exceed the permissible limit values in soil.

“…Strains of Paenibacillus and Bacillus are known to produce various enzymes and useful molecules, including exo-polysaccharides (EPS), biosurfactants, and enzymes such as oxygenases, dehydrogenases, amylases, cellulases, hemicellulases, lipases and lignilolytic enzymes (Grady et al 2016). Considering the physiological and biochemical properties of Paenibacillus and Bacillus strains, they exhibit the ability to degrade aliphatic and aromatic organic pollutants (Guisado et al 2015, Mauricio-Gutiérrez et al 2020, Jayapal et al 2023. Both genera, Paenibacillus and Bacillus, are Grampositive, endospore-forming bacteria capable of thriving in both aerobic and anaerobic conditions.…”

This study represents the first culture-independent profiling of microbial diversity in post-processing wastewater from underground coal gasification (UCG) processes. Three types of post-processing wastewater, named W1, W2 and W3, were obtained from three UCG processes involving two types of coal and two gasification agents, namely oxygen-enriched air and oxygen. Very high concentrations of BTEX (benzene, toluene, ethylbenzene, xylene), polyaromatic hydrocarbons (PAHs), and phenol were detected in the wastewater, classifying it into the fifth toxicity class, indicating very high acute toxicity. The values for the Shannon (H), Ace and Chao1 indices in W2 were the lowest compared to their values in W1 and W3. The dominate phyla were Proteobacteria, contributing 84.64% and 77.92% in W1 and W3, respectively, while Firmicutes dominated in W2 with a contribution of 66.85%. At the class level, Gammaproteobacteria and Alphaproteobacteria were predominant in W1 and W3, while Bacilli and Actinobacteria were predominant in W2. Among Bacilli, the Paenibacillus and Bacillus genera were the most numerous. Our results suggest that the main differentiating factor of the bacterial structure and diversity in the wastewater could be the gasification agent. These findings provide new insights into the shifting patterns of dominant bacteria in post-processing wastewater and illustrate the spread of bacteria in industrial contaminated wastewater.

“…The mining industry is in constant development to reduce waste generation, improve storage as well as treatment techniques for its tailings deposits. Among them, strategies related to: (i) improvement of soil mechanical properties; (ii) chemical and physical stabilization; (iii) liquefaction, permeability and neutralization of acid leachates; (iv) resistance to water lixiviation, seismic action and wind erosion; (v) bioremediation, phytoremediation and biomineralization, are some of the most studied techniques ( Edraki et al, 2014 ; De Giudici et al, 2019 ; Kiventerä et al, 2019 ; Barati et al, 2020 ; Kaseng et al, 2020 ; Kiventerä et al, 2020 ; Xie and van Zyl, 2020 ; East and Fernandez, 2021 ; Gerding et al, 2021 ; Rezasoltani, 2021 ; Woodcock, 2021 ; Zandarin, 2021 ; Jayapal et al, 2023 ; Si et al, 2023 ). Currently, biotechnological applications using biomineralizing microorganisms have generated interest in the materials industry, because they significantly reduce the energy demand to produce biocement if compared to that necessary for the conventional cement and, moreover, they can be used successfully in the neutralization of toxic elements such as PTEs or fossil fuel residues ( Akyel et al, 2022 ).…”

In this study, native ureolytic bacteria were isolated from copper tailings soils to perform microbial-induced carbonate precipitation (MICP) tests and evaluate their potential for biocement formation and their contribution to reduce the dispersion of particulate matter into the environment from tailings containing potentially toxic elements. It was possible to isolate a total of 46 bacteria; among them only three showed ureolytic activity: Priestia megaterium T130-1, Paenibacillus sp. T130-13 and Staphylococcus sp. T130-14. Biocement cores were made by mixing tailings with the isolated bacteria in presence of urea, resulting similar to those obtained with Sporosarcina pasteurii and Bacillus subtilis used as positive control. Indeed, XRD analysis conducted on biocement showed the presence of microcline (B. subtilis 17%; P. megaterium 11. 9%), clinochlore (S. pasteurii, 6.9%) and magnesiumhornblende (Paenibacillus sp. 17.8%; P. megaterium 14.6%); all these compounds were not initially present in the tailings soils. Moreover the presence of calcite (control 0.828%; Paenibacillus sp. 5.4%) and hematite (control 0.989%; B. subtilis 6.4%) was also significant unlike the untreated control. The development of biofilms containing abundant amount of Ca, C, and O on microscopic soil particles was evidenced by means of FE-SEM-EDX and XRD. Wind tunnel tests were carried out to investigate the resistance of biocement samples, accounted for a mass loss five holds lower than the control, i.e., the rate of wind erosion in the control corresponded to 82 g/m2h while for the biocement treated with Paenibacillus sp. it corresponded to only 16.371 g/m2h. Finally, in compression tests, the biocement samples prepared with P. megaterium (28.578 psi) and Paenibacillus sp. (28.404 psi) showed values similar to those obtained with S. pasteurii (27.102 psi), but significantly higher if compared to the control (15.427 psi), thus improving the compression resistance capacity of the samples by 85.2% and 84.1% with respect to the control. According to the results obtained, the biocement samples generated with the native strains showed improvements in the mechanical properties of the soil supporting them as potential candidates in applications for the stabilization of mining liabilities in open environments using bioaugmentation strategies with native strains isolated from the same mine tailing.
