Bacteria help remove sulphur from fossil fuels

• Scientists from CSIR-Institute of Minerals and Materials Technology (CSIR-IMMT) in Bhubaneswar used four bacterial strains that use dibenzothiophene (an organic sulphur compound which is a major contaminant of fossil fuel) as an energy source thereby getting rid of the sulphur.

• Using novel bacterial strains, scientists have successfully removed sulphur from fossil fuels such as petroleum and coal.

• Sulphur is one of the major pollutants emitted during the combustion of fossil fuels.

=> Significance

• The new process is also eco-friendly and economical, and these new bacterial strains can be potentially explored for the removal of sulphur from fossil fuels on a commercial scale.
