Stimulation of rhamnolipid biosurfactants production in Pseudomonas aeruginosa AK6U by organosulfur compounds provided as sulfur sources

Biotechnology Reports, 2015
A Pseudomonas aeruginosa AK6U strain produced rhamnolipid biosurfactants to variable extents when grown on MgSO4 or organosulfur compounds as sulfur sources and glucose as a carbon source. Organosulfur cultures produced much higher biosurfactants amounts

BIOTRANSFORMATION AND REMOVAL OF SULFUR FROM DIBENZOTHIOPHENE USING IMPROVED BIOCATALYTIC METHODS

CT&F Ciencia, Tecnología & Futuro, 1998
Three methods for the removal of sulfurfrom dibenzothiophene were evaluated using biocatalytic processes. The methods were a microbial, an enzymatic and a combined one that involves a previous enzymatic oxidation followed by microbial degradation.

Anaerobic biodesulfurization of thiophenes

Distillates from crude oil such as diesel and fuel oil may contain significant amounts of dibenzothiophenes and their alkylated derivatives, containing organically bound sulfur. Combustion of those fossil fuels leads to the release of polluting sulfur dioxide into the atmosphere, where it causes 'acid rain'.

Study the effect of environmental factors and different carbon sources on dibenzothiophene desulfurization by Exophiala spinifera

یافته‌های نوین در علوم زیستی, 2019
It is necessary to reduce the amount of sulfur in fossil fuels due to direct impact of the quality of these fuels on the environment. In this research, a novel fungus strain of Exophiala spinifera, namely FM, was used to desulfurize dibenzothiophene (DBT)
