A process for treating liquid hydrocarbon, includes the steps of providing a liquid hydrocarbon containing complex sulfur-containing compounds, providing a bioactive material selected from or derived from members of genus Alcaligenes; and exposing the liquid hydrocarbon to the bioactive material under effective conditions such that the bioactive material interacts with the complex sulfur compounds and transforms the organic sulfur-containing compounds into inorganic sulfur compounds.
