南开菊酯微生物降解的研究
THE STUDY ON THE BIODEGRADATION OF NANKAI-PYRETHRIN BY AEROBE
-
摘要: 南开菊酯(高效反体氯氰菊酯),是一种新型广谱杀虫剂,经研究可被微生物降解。其溶液中细菌总数的消长,与其降解速率呈正相关关系,说明南开菊酯可被微生物分解利用,在研究土壤混合菌对其降解作用的同时,发现筛选出优势菌株(NK102)。Abstract: Nankai-pyrethrin, namely high effective transisomer cyperme-thrin, is a new type insecticide in a wide range of lethal variety. The experimental results show that Nankai-pyrethrin can be degraded by aerobe. As the total number of bacteria is in direct proportion to the degradation speed of Nankai-pyrethrin, it proves that Nankai-pyrethrin can be decomposed and utilized by aerobe.In the process of the experiment, the dominant (NK102) is selected, and found that its degradation effect to Nankai-pyrethrin is of significance.
