Abstract

Results of phenol biodegradation by both, free and immobilized Pseudomonas putida cells are presented. The influence of pH and the initial substrate concentration was analyzed. On the other hand, several tests of cell adaptation were carried out in order to increase the capacity and the rate of the biodegradation. The behaviour of free and immobilized microorganisms, was similar, reaching a maximum biodegradation capacity of 2000 ppm at an initial pH 6.6 and temperature 30 degrees C. Finally, two different kinetic models, for low and high phenol concentration were assayed.

摘要

本文展示了游离和固定化恶臭假单胞菌细胞对苯酚的生物降解结果。分析了pH值和初始底物浓度的影响。另一方面，进行了多项细胞适应性测试，以提高生物降解能力和速率。游离和固定化微生物的行为相似，在初始pH值为6.6、温度为30摄氏度时，最大生物降解能力达到2000 ppm。最后，对低苯酚浓度和高苯酚浓度的两种不同动力学模型进行了测定。
