Scientists from CSIR-Institute of Minerals and Materials Technology (CSIR-IMMT) have found four bacterial strains that remove sulfur from fossil fuels such as petroleum and coal.
The four bacterial strains are Rhodococcus rhodochrous, Arthrobacter sulfureou, Gordonia rubropertinita and Rhodococcus erythropolis.
Sulfur is one of the major pollutants emitted during the combustion of fossil fuels.
They use dibenzothiophene, an organic sulfur compound which is a major contaminant of fossil fuel as energy source thereby getting rid of sulfur.
The process of bio-desulfurization using these four bacterial strains is also eco-friendly and economical.
