| 摘 要： | 研究了硝基苯的生物降解过程,探讨了在降解过程中加入环糊精造成的影响.结果表明,环糊精可以提高降解菌对硝基苯的耐受浓度,缩短降解菌的停滞时间,促进降解菌的生长,加快硝基苯的降解.这种作用与环糊精和硝基苯的浓度有关,硝基苯浓度高于降解菌的耐受浓度时影响更为显著;环糊精浓度越高,影响越大.

| Abstract: | Influence of cyclodextrin addition in the degradation process on the biodegradability of nitrobenzene was explored with studies on the biodegradation of nitrobenzene. Cyclodextrin could increase significantly the degradation bacterial durability concentration on nitrobenzene, shorten the bacterial retention time, promote the growth of the degradation bacterial and accelerate the degradation of nitrobenzene. This function was related with the concentration of cyclodextrin and nitrobenzene. When the concentration of nitrobenzene was more than the durable concentration of the degradation bacteria the influence was more remarkable. The higher the concentration of cyclodextrin, the greater the influence. |
