Reduction of sulphate released to the atmosphere by specific bacteria
Khalil Y. Mataqi and Fadheelah A. Gholoum


Oil compounds release sulphur dioxide into the atmosphere leading to the generation of acid rain. Bio-desulphurization technology can be used to reduce the sulphur prior to the decomposition of fossil fuels. The use of microbes to desulphurize fossil fuel provides an improved process of organic sulphur removal before its combustion. In this study the ability of five bacterial strains (3s5a, 3s17d, 3s20d 3s19d and jpn) to desulfurize oil fractions (e.g. gas oil, naphtha and oil) was investigated. Optimization of growth conditions such as ph, temperature; and growth sources (carbon and sulphur) enabled the identification of desulfurization capability in these strains.
