May 5 , 2018 2267 days 894 0
  • 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.
