摘要
通过对硝基苯和对硝基苯酚混合体系微生物降解过程的研究,探讨了在降解过程中加入-环糊精及其衍生物羧甲基--环糊精(CMCD)对混合体系微生物降解的影响.研究表明,对硝基苯酚不能被单独降解;硝基苯能与对硝基苯酚产生共代谢作用,对硝基苯酚浓度影响混合体系的降解程度.加入环糊精能促进对硝基苯酚的降解率,影响程度与对硝基苯酚的浓度和环糊精的种类及量有关.
Through studies on the biodegradation course of nitrobenzene and p-nitrophenol mixed system, the influence of adding -cyclodextrin and its derivative carboxymethyl--cyclodextrin (CMCD) on the biodegradation of the mixed system was explored. P-nitrophenol could not be degraded alone. P-nitrophenol could produce co-metalolism with nitrobenzene; and its concentration influenced the degradation degree of the system. Addition of cyclodextrin could promote the degradation rate of p-nitrophenol, the degree of influence was related to the concentration of p-nitrophenol and the kind and amount of cyclodextrin.
