耐酚优势菌细胞固定化效果的研究

Effects on Cell Fixation for Tolerant Phenol Super-Bacterium

应用耐酚能力达 1760mg/L的优势菌种W1、M2 和W2 进行了细胞固定化效果的研究 .结果表明 ,几种包埋剂中机械强度和稳定性能均以海藻酸钠较好。菌种W1的适宜包埋条件为 3 %浓度的海藻酸钠 ,包埋比为2 :2 5 ;菌种M2 和W2 的适宜包埋条件为 5 %浓度的海藻酸钠 ,包埋比为 4:2 5。在处理炼油废水时 ,采用添加营养盐的方法 ,固定后的细菌 12h内降酚率可达到 96.

Using super-bacteria W_2, M_2 and W_1 with the phenol decomposition ability reaching to 1760 mg/L ,the effects of their cell fixation have been carried out in the paper. The results show as following :among the parcel materials , sodium alginate is better in the stability and mechanical strength as a small-ball than others. The suitable parcel proportion of Bacterium W_1 and Sodium alginate in 3% density is 2: 25, that of W_2 /M_2 and Sodium alginate in the density of 5% is 4: 25.For handling the waste water of oil refinery,the good results can be given by using the method to add other nourish materials, the phenol decomposition rate reaches 96.8% within 12 hrs .
