CHANGES IN SHALE OIL COMPOSITION AND YIELD AFTER BIOLEACHING BY BACILLUS MUCILAGINOSUS AND THIOBACILLUS FERROOXIDANS; pp. 146–154 [PDF]
Oil Shale, 2017 Bacillus mucilaginosus (B. mucilaginosus) and Thiobacillus ferrooxidans (T. ferrooxidans) have been earlier shown to be conducive to the demineralization of oil shale and thus improve shale oil yield.

Sulfide oxidation by spheroplasts of Thiobacillus ferrooxidans [PDF]
Applied and Environmental Microbiology, 1978 Thiobacillus ferrooxidans is an acidophilic organism important to metal leaching of low-grade ores. The aforementioned importance is related to the ability of the bacterium to oxidize reduced iron and sulfur, principally found in nature as pyrite (FeS2).

Recent advances in microbial capture of hydrogen sulfide from sour gas via sulfur‐oxidizing bacteria
Engineering in Life Sciences, Volume 21, Issue 10, Page 693-708, October 2021., 2021 Abstract Biological desulfurization offers several remarkably environmental advantages of operation at ambient temperature and atmospheric pressure, no demand of toxic chemicals as well as the formation of biologically re‐usable sulfur (S0), which has attracted increasing attention compared to conventionally physicochemical approaches in removing ...

GeoHealth, Volume 5, Issue 10, October 2021., 2021 Abstract Mine wastes pollute the environment with metals and metalloids in toxic concentrations, causing problems for humans and wildlife. Microorganisms colonize and inhabit mine wastes, and can influence the environmental mobility of metals through metabolic activity, biogeochemical cycling and detoxification mechanisms. In this article we review the

A Rapid and Facile Approach for the Recycling of High‐Performance LiNi1−x−yCoxMnyO2 Active Materials
ChemSusChem, Volume 14, Issue 1, Page 441-448, January 7, 2021., 2021 Recycle and re‐synthesize: Spent LiNi0.8Co0.1Mn0.1O2 (NCM‐811) from Li‐ion batteries is recovered by a facile and inexpensive recycling approach. After a series of decomposition and dissolution reactions, Ni/Co/MnC2O4 and Li2CO3 are formed, which serve as precursors for the re‐synthesis of NCM‐811.

Molecular genetics of Thiobacillus ferrooxidans
Microbiological Reviews, 1994 Thiobacillus ferrooxidans is a gram-negative, highly acidophilic (pH 1.5 to 2.0), autotrophic bacterium that obtains its energy through the oxidation of ferrous iron or reduced inorganic sulfur compounds. It is usually dominant in the mixed bacterial populations that are used industrially for the extraction of metals such as copper and uranium from ...

Role of Atmospheric Aerosol Content on Atmospheric Corrosion of Metallic Materials
International Journal of Corrosion, Volume 2021, Issue 1, 2021., 2021 Despite extensive work on improving atmospheric corrosion resistance in metals, i.e., steel and alloy, the corrosion rate on the metallic surface is higher at some localized geographical area of the globe. Despite the visible successes in recent coating technology in curbing environmental conditions, it is proposed that the recent increase of ...
