Abstract
One of the problems limiting industrial application of fossil fuel biodesulfurization is the cost of culture media used to grow the microorganisms involved in the process. The use of alternative carbon sources resulting from agro-industrial by-products could be a strategy to reduce the investment in the operating expenses of a future industrial application.
Gordonia alkanivorans 1B has been described as a fructophilic desulfurizing bacterium, a property which opens a new interest in alternative carbon sources rich in fructose. Authors report results of a study to evaluate the use of sugar beet molasses (SBM) in the dibenzothiophene (DBT) desulfurization process using strain 1B. Study results showed the high potential of SBM to be used in a future industrial fossil fuel biodesulfurization process using strain 1B.
