Highly integrated adaptive mechanisms in Spiribacter halalkaliphilus, a bacterium abundant in Chinese soda‐saline lakes

Environmental Microbiology, Volume 23, Issue 11, Page 6463-6482, November 2021., 2021
Summary Soda‐saline lakes are polyextreme environments inhabited by many haloalkaliphiles, including one of the most abundant Spiribacter species. However, its mechanisms of adaptation are not ecophysiologically characterized. Based on a large‐scale cultivation strategy, we obtained a representative isolate of this Spiribacter species whose relative ...

The Alternating Growth of Bacteria within a Consortium During Desulfurization of Coal

Environment and Natural Resources Journal, 2022
Efforts to reduce organic sulfur in coal are taken through biodesulfurization by using desulfurization bacteria to release covalently-bound sulfur from the coal matrix. Coal is a complex hydrocarbon material that requires collaboration from more than one

Thermophilic carbon-sulfur-bond-targeted biodesulfurization [PDF]

Applied and Environmental Microbiology, 1997
Petroleum contains many heterocyclic organosulfur compounds refractory to conventional hydrodesulfurization carried out with chemical catalysts. Among these, dibenzothiophene (DBT) and DBTs bearing alkyl substitutions are representative compounds.

The Surfactant Tween 80 Enhances Biodesulfurization [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT In biocatalytic conversions, substrates and products may display inhibitory or toxic effects on the biocatalyst. Rhodococcus erythropolis 1awq could further remove sulfur from hydrodesulfurized diesel oil, and the biodesulfurization was enhanced by the surfactant Tween 80.

Biodesulfurization of Cayirhan Lignites

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2006
In this study, the lignite was improved oxidizing sulfur compounds by Thiobacillus thiooxidans and Thiobacillus ferrooxidans bacteria. Experiments in the batch reactors have been carried out 20% aqueous suspension of coal samples. Sugar beet molasses was used as the bacterial substrate.
