摘要
该文介绍了巴氏醋酸杆菌以乙醛为惟一碳源和能源,通过合成细菌纤维素而将含乙醛的废水中的乙醛净化,其对乙醛的最大净化浓度为2.2g/L.试验结果表明,适宜的培养条件为:培养基初始pH值5.0～5.5,接种量为5%,发酵培养温度为30℃,摇瓶转速100r/min.对含乙醛1.4g/L的废水进行处理,培养4d时的最大净化率达98%以上.
This paper introduced the Acetobacter pasteurianus using acetaldehyde as unique carbon resource, depurate acetaldehyde in wastwater through synthesizing bacterial cellulose by Acetobacter pasteurianus . The biggest content of depurated acetaldehyde was 2.2%, and the feasible conditions were pH5.0～6.0, quantity of inoculation 5%, the temperature 30℃, and shaking-flask speed 100 r/min. The maximum depurating rate was over 98% in 4 days.
