Substrate preferences in biodesulfurization of diesel range fuels by Rhodococcus sp. strain ECRD-1

Article Abstract:

Research shows that the biosulfurization capacity of Rhodococcus sp. strain ECRD-1 encompasses all isomers of dibenzothiophene and less avidly the substituted benzothiophenes. Further, some sulfidic sulfur compounds are also substrates for desulfurization.

Fate of selenate and selenite metabolized by Rhodobacter sphaeroides

Article Abstract:

The purple nonsulfur bacterium Rhodobacter sphaeroides converts selenate and selenite into organic forms and the red elemental form. Very little is produced in volatile form.

A novel selenite- and tellurite-inducible gene in Escherichia coli

Article Abstract:

Researchers describe the isolation of the gutS gene in E. coli. This gene is induced by selenium and telluride, which are both toxic to living cells in high concentrations.
