Sulfur can be removed from benzothiophene (BT) by some bacteria without breaking carbon-carbon bonds. However, a clear mechanism for BT desulfurization and its genetic components have not been reported in literatures so far. In this study, we used comparative transcriptomics to study differential expression of genes in Gordonia terrae C-6 cultured with BT or sodium sulfate as the sole source of...
We report here the whole-genome sequence of a biodesulfurizing bacterium, Gordonia sp. strain IITR100. The bacterium has the unique ability to desulfurize both aliphatic and aromatic organosulfurs. The draft genome sequence will provide insights into the various genes and regulators involved in biodesulfurization and other catabolic pathways.
Gordona terrae strain C-6 was isolated from oil-contaminated soil and is capable of desulfurizing benzothiophene (BT). Here we report the draft genome sequence of G. terrae strain C-6, which may help to reveal the genetic basis of the BT biodesulfurization pathway.
Rhodococcus erythropolis strains have shown excellent characteristics in petroleum oil biodesulfurization. Here we present the first announcement of the draft genome sequence of an efficient biodesulfurizing bacterium named R. erythropolis XP (7,229,582 bp). The biodesulfurizing genes dszABC are located on a plasmid, while the flavin reductase gene dszD is located on the chromosome.
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. Tween 80 was shown to decrease the product concentration associated with the cells, reducing product inhibition.
Biotechnological techniques enabling the specific removal of sulfur from fossil fuels have been developed. In the past three years there have been important advances in the elucidation of the mechanisms of biodesulfurization; some of the most significant relate to the role of a flavin reductase, DszD, in the enzymology of desulfurization, and to the use of new tools that enable enzyme enhanceme...
sulfur emission from coal combustion presents many environmental problems. the techniques used to reduce the amount of sulfur in coal before combustion, include physical, chemical and biological processes.biological processes based on degradation of sulfur compounds by microorganisms offer many advantages over the conventional physical and chemical processes. the processes are performed under m...
