An experimental study of the effects of bacteria on asphaltene adsorption and wettability alteration of dolomite and quartz

Scientific Reports, 2023
The adsorption of asphaltene on the rock surface and the changes in its wettability are very relevant issues in flow assurance and oil recovery studies, and for carbonate reservoirs, they are even more important.

Effect of Immobilizing Bacillus megaterium on the Compressive Strength and Water Absorption of Mortar

Journal of Chemistry, Volume 2022, Issue 1, 2022., 2022
The world’s growing population and industrialization have led to increased construction activities. This has increased the amount of waste aggregates which can be recycled in construction and cut the cost of infrastructure development. This study, therefore, reports the experimental findings for the effect of immobilizing Bacillus megaterium on the ...

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 ...

Abundant and diverse arsenic‐metabolizing microorganisms in peatlands treating arsenic‐contaminated mining wastewaters

Environmental Microbiology, Volume 22, Issue 4, Page 1572-1587, April 2020., 2020
Summary Mining operations produce large quantities of wastewater. At a mine site in Northern Finland, two natural peatlands are used for the treatment of mining‐influenced waters with high concentrations of sulphate and potentially toxic arsenic (As).

Bio-modulation of galena and sphalerite surfaces using Thiobacillus thiooxidans

, 2001
The interaction of Thiobacillus thiooxidans (T. thiooxidans) with sphalerite and galena has been investigated through adsorption, electrokinetic, and flotation studies. The amount of T. thiooxidans cells adsorbed onto galena and sphalerite is found to be
