“…Bioconversion of coal by fungi has been the subject of thorough investigation since the early 1980s [1][2][3][4][5][6][7][8][9][10][11]. A wide range of bioconversion mechanisms are used by fungi and these include biosolubilization [9,12,13], liquefaction [14,15], and depolymerization [16][17][18].…”

Fundamental processes involved in the microbial degradation of coal and its derivatives have been well documented. A mutualistic interaction between plant roots and certain microorganisms to aid growth of plants such as Cynodon dactylon (Bermuda grass) on hard coal dumps has recently been suggested. In the present study coal bioconversion activity of nonmycorrhizal fungi was investigated in the C. dactylon/coal rhizosphere. Fungal growth on 2% Duff-agar, gutation formation on nitric acid treated coal and submerged culture activity in nitrogen-rich and -deficient broth formed part of the screening and selection of the fungi. The selected fungal isolates were confirmed to be found in pristine C. dactylon/coal rhizosphere. To simulate bioconversion, a fungal aliquot of this rhizosphere was used as inoculum for a Perfusate fixed bed bioreactor, packed with coal. The results demonstrate an enhanced coal bioconversion facilitated by low molecular weight organics and the bioconversion of coal may be initiated by an introduction of nitrogen moieties to the coal substrate. These findings suggest a phyto-bioconversion of hard coal involving plant and microbes occurring in the rhizosphere to promote the growth of C. dactylon. An understanding of this relationship can serve as a benchmark for coal dumps rehabilitation as well as for the industrial scale bioprocessing of hard coal.

“…Interestingly, they found that when the fungal spores germinated, there was no affinity to the coal, but in mature stage many coal particles adhered to the fungal cell wall and the older hyphae became completely coated with the coal layer. Cohen and Gabriele (1982) found that the two white rot fungi, Trametes versicolor and Poria monticola were able to convert leonardite, a low rank coal deposit in North Dakota. Few more researchers have also shown that the fungi and actinomycetes are able to solubilise small amount of 3.2 N nitric acid oxidized coals in liquid culture (Quigley et al, 1988).…”

Coal is an important non-renewable source of energy, which is being constantly used by mankind for various purposes. Coal mining activities affect the surrounding ecosystem by contaminating it with traces of toxic metals, which may accumulate and affect the diversity and abundance of biological communities. A number of microorganisms, such as, filamentous fungi, yeasts and bacteria are known to degrade coal by their enzymatic action and use it as the sole source of carbon. In addition, the indoor environments of coal mines possess bioaerosols, which may include living or dead allergens, pathogenic or non-pathogenic bacteria, fungi, viruses, mycotoxins, bacterial endotoxins, peptidoglycans, etc., that may cause skin, respiratory tract and other health problems. This article throws light on the impact of coal mining on the surrounding ecosystem, degradation of coal by the microbial inhabitants and their effects on the health of miners.

“…Some coals (mostly low-rank and in some cases bituminous coals) have the potential to be solubilized by the action of microorganisms [7]. There are several microorganisms, from different taxa, for which a coal solubilization capability was demonstrated ( Table 17).…”

This paper presents challenging opportunities for production of liquid and gaseous fuels by biotechnology. From the liquid fuels, ethyl alcohol production has been widely researched and implemented. The major obstacle for large scale production of ethanol for fuel is the cost, whereby the substrate represents one of the major cost components. Various scenarios will be presented for a critical assessment of cost distribution for production of ethanol from various substrates by conventional and high rate processes. The paper also focuses on recent advances in the research and application of biotechnological processes and methods for the production of liquid transportation fuels other than ethanol (other oxygenates; diesel fuel extenders and substitutes), as well as gaseous fuels (biogas, methane, reformed syngas). Potential uses of these biofuels are described, along with environmental concerns which accompany them. Emphasis is also put on microalgal lipids as diesel substitute and biogas/methane as a renewable alternative to natural gas. The capturing and use of landfill gases is also mentioned, as well as microbial coal liquefaction. Described is also the construction and performance of microbial fuel cells for the direct high‐efficiency conversion of chemical fuel energy to electricity. Bacterial carbon dioxide recovery is briefly dealt with as an environmental issue associated with the use of fossil energy.
