摘要
运用遗传算法 ,对利用莫格假丝酵母由木糖生产木糖醇的发酵培养基优化进行研究。用 40个实验样本完成了 6种培养基成份、50个浓度水平的优化任务。实验结果表明 :利用遗传算法可优化培养基成份含量 ,取得更好的发酵效果。按照优化后的培养基组成 ,由 50 g/L木糖获得了 2 9.7g/L木糖醇 ,比优化前提高5.7%。
Medium optimization of the batch fermentation for producing xylitol from D xylose by Candida mogii using genetic algorithms (GA) was studied. The 50 concentration levels of 6 medium components were optimized within 40 experiments. The results showed that GA can be applied in the medium optimization and better results were obtained. Employing optimized medium composition, a final xylitol concentration of 29.7 g/L was obtained from 50 g/L xylose, and it was improved by 3.5% compared to the results with the medium before optimization.
