An effective strain of bio-surfactant producing bacteria named BSZ-07,identified as Pseudomonas aeruginaosa,was obtained from oil-polluted soil. This paper described the process for the bacteria screening and the experiment regarding orthogonal test which leads to the optimum condition,under which surface tension in fermentation broth could be reduced. According to the analysis with FTIR,the bio-surfactant is rhamnolipid.
