“…Several other studies also indicated the stress tolerance characteristics of PGP bacteria. For example, Barman et al, in their recent study [ 192 ], isolated and characterized 10 bacterial strains from the coal dumping area; among them, Bacillus toyonensis DD1, B. mycoides DD2, B. velezensis DD9, and B. flexus DD10 strains demonstrated tolerance to two or more heavy metals. Additionally, these PGP bacteria could solubilize phosphate, produce IAA, produce siderophore, and show ACC deaminase activity.…”

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 ecosystem functioning. The high oxygen content, organic fractions, and lignin-like structures of lower-rank coals may provide effective means for microbial attack, still representing a greatly unexplored frontier in microbiology. Coal degradation/conversion technology by native bacterial and fungal species has great potential in agricultural development, chemical industry production, and environmental rehabilitation. Furthermore, native microalgal species can offer a sustainable energy source and an excellent bioremediation strategy applicable to coal spill/seam waters. Additionally, the measures of the fate of the microbial community would serve as an indicator of restoration progress on post-coal-mining sites. This review puts forward a comprehensive vision of coal biodegradation and bioprocessing by microorganisms native to coal environments for determining their biotechnological potential and possible applications.

“…For example, the lead (Pb) immobilization potential of phosphate solubilizing bacteria isolated from heavy metal contaminated soils was reported previously 18 . Metal resistant and plant growth‐promoting bacteria were previously isolated from gold mining soil, coal dumping, and metal‐contaminated mine tailings 19–21 . Likewise, Jain et al 3 linked bacteria isolated from the rhizosphere of B. monnieri with nutrient mineralization and contaminant degradation in acidic mine‐affected soil.…”

The phytostabilization of acid mine spoil by industrially important aromatic crops could be a sustainable solution with minimum input for the problem associated with acidic mine spoil-affected areas. In the present study, the suitability of Pelargonium graveolens for phytostabilization of acidic mine spoil has been investigated in three different combinations (T1: 100% soil; T2: 100% mine spoil, T3: 75 mine spoil: 25 soil and T4: 50 mine spoil: 50 soil). The plant growth performance, metal accumulation, ecological indices, soil properties, enzymes, and microbial diversity along with the identification of dominant bacterial isolates were investigated in the study. The results indicated that mine spoil was highly acidic (pH 3.01) and rich in minerals and toxic metals. The values of the tolerance index and oil content of P. graveolens L under different treatments varied from 43% to 89% and from 0.10 to 0.13% without affecting oil quality, respectively. Bioconcentration (BCF) and translocation factor (TF) indicated that the P. graveolens can be used as a phyto-excluder for Al, Fe, Cr, Zn, and Pb and phytoextractor for Cu, Ni, and Mn. The plantation of P. graveolens enhanced the microbial biomass and enzymatic activities of soil and immobilized the metals. The increase in the Shannon index from 1.67-1.86 to 1.9-2.61 suggested enhanced bacterial diversity after plantation. The identify bacterial isolates were metal tolerant and plant growth promoters. The study suggested that P. graveolens is suitable for the phytostabilization purpose of acidic mine spoils along with the economic return.
