【Abstract】 Medium optimization of the culture for oil degradation by Candida tropicalis using genetic algorithms (GA) was studied. The 64 concentration levels of 6 medium components were optimized within 50 experiments. The results show that GA can be applied in the medium optimization and better results are obtained. Employing optimized medium composition, a final oil degradation rate of 95.4% was obtained and it was improved by 6.94% compared to the results with the medium before optimization. GA is an efficient new medium optimum method which is superior to the other optimum means such as orthogonal array method.更多还原
