“…Also, investigations conducted on a same Indian coal sample aimed at comparison of desulfurization capacity of two bacteria, Pseudoxanthomonas sp. and Ralstonia sp., showed a better performance of the previous one [17,43]. Results from other investigations of coal remediation using other bacterial species showed sulfur removal values of 27%, 50%, and 31-51% [42,44,45].…”

The Raša Bay (North Adriatic, Croatia) has been receiving various pollutants by inflowing streams laden with untreated municipal and coalmine effluents for decades. The locality was a regional center of coalmining (Raša coal), coal combustion, and metal processing industries for more than two centuries. As local soil and stream water were found to be contaminated with sulfur and potentially toxic trace elements (PTEs) as a consequence of weathering of Raša coal and its waste, some clean-up measures are highly required. Therefore, the aim of this study was to test the remediating potential of selected microorganisms and synthetic zeolites in the case of soil and coal-mine water, respectively, for the first time. By employing bacterial cultures of Ralstonia sp., we examined removal of sulfur and selected PTEs (As, Ba, Co, Cr, Cu, Ni, Pb, Rb, Se, Sr, U, V, and Zn) from soil. The removal of sulfur was up to 60%, arsenic up to 80%, while Se, Ba, and V up to 60%, and U up to 20%. By applying synthetic zeolites on water from the Raša coalmine and a local stream, the significant removal values were found for Sr (up to 99.9%) and Ba (up to 99.2%) only. Removal values were quite irregular (insignificant) in the cases of Fe, Ni, Zn, and Se, which were up to 80%, 50%, 30%, and 20%, respectively. Although promising, the results call for further research on this topic.

Bacterial strains are successfully employed to desulfurize dibenzothiophene which may be determined by chromatography, HPLC and GC-Mass spectrometry. Strains of Ralstonia sp ., Pseudoxanthomons sp. and Rhodococcus sp. were used in the present investigation. Only Rhodococcus sp. was able to convert dibenzothiophene (DBT) into 2-hydroxy biphenyl (2-HBP). Gibb’s assay blue colour indicates the conversion of DBT into 2-HBP and brown colour indicates complete consumption of DBT by bacteria. After two days of bacterial treatment, there was no further removal of DBT. Conversion of DBT into 2-HBP was monitored through HPLC for six days of entire experiment.

“…They have found out that the removal ef ciency was more than 80% for Ni, Zn, Cd, Cu, and Cr, and 45% in the case of Pb. The authors have also been working on the desulphurisation of coal by using microorganisms Ralstonia sp and Pseudoxanthomonas sp (Singh et al, 2012b). One of their latest papers (Singh et al, 2017a) presents the results of the petrological considerations in relation to the demineralization of Rajmahal Gondwana coals by means of Pseudomonas mendocina B6-1.…”

Fossil fuels, coal in particular, are indispensable sources of energy necessary for today's technological and economical progress throughout the world. Their burning releases numerous environmental contaminants, like CO 2 , SO 2 , and a range of organic and inorganic compounds. Arguably, however, and despite the fact that these emissions have resulted in air pollution and regional acid rain problems, there is no evidence yet of their usage completely replaced by a low-CO 2 -producing energy source. Coal, due to its unique composition and characteristics, has been actively investigated by scientists and technologists from various disciplines in a search for economically valuable metals and medically active substances. Also, coal is used universally for the fabrication of new nanomaterials in laboratories, and utilized in wastetreatment and clean-coal technologies. The aim of this paper is to focus on the latest advancements in coal research of leading international scientists from India, China, and the USA. Also, this paper is brie y presenting selected papers of several Indian and Croatian research groups addressing environmental issues and emerging waste-treatment technologies. Although the two countries are di erent from a geographical, historical, economical, and industrial point of view, they both have been linked with coal extraction and its usage in power generation and associated heavy industries.
