Abstract: The possibility of application of biochemical method on desulfurization technique is discussed. Although desulfurization from crude oil by caustic soda is simple, it has low sulfide removal efficiency and produces a large quantity of waste water after treatment. The application of biochemical method has modified this situation. In addition, this technology shows good prospects in removing sulfide coming from waste water and oil products. It can simplify the treating process, lower the cost and prevents effe...

Key words: desulfurization, organism, environmental pollution, sulfide
