| 摘 要： | 菌株Ochrobactrum sp. CH10是从北京元大都城垣遗址处的人工湿地筛选到的高效苯酚降解菌.以苯酚为唯一碳源和能源对其进行了生长和苯酚降解特性的研究.该菌生长和降解苯酚的适宜条件为30℃、初始pH 7.0、接种量为5%.在该条件下,初始苯酚浓度为400 mg·L-1,24 h时苯酚完全被降解;初始苯酚浓度为900 mg·L-1时,44 h的降解率为92.3%;初始苯酚浓度为1 000 mg·L-1,48 h时的降解率为82.2%.对该菌株苯酚降解动力学过程进行模拟,符合基质抑制型的Haldane模型,各参数分别为:υmax(最大比降解速率)0.126 h-1,KS(半饱和常数)23.53 mg·L-1,KI(抑制常数)806.1 mg·L-1.该菌在苯酚中的生长动力学符合Andrews模型,表现出与苯酚降解相似的趋势.该菌为目前所发现的Ochrobactrum菌属中苯酚降解能力最强的菌株.该菌株在高效处理含酚废水方面具有广阔的应用前景.
