Influence of cyclodextrin on the biodegradation of nitrobenzene.

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.
