| 摘 要： | 从大港油田石油污染土壤中分离筛选出1株原油降解菌X3，对原油的降解率达72．6％，经鉴定X3菌株属于假单胞菌属（Psedomonas）。利用生物摇床对X3菌株降解原油的实验发现，共代谢基质α-乳糖对X3菌株降解原油有促进作用，可使原油降解率提高到80．3％；而葡萄糖和蔗糖对X3菌株降解原油有抑制作用。Fe2＋对X3菌株的降解原油也有促进作用，在α-乳糖和Fe2＋的共同作用下，X3菌株对原油的降解率可达82．3％；K＋和Mg2＋对X3菌株降解原油则有抑制作用。在FeSO4质量浓度为0．2～0．3mg／L时，X3菌株对原油的降解率最高，FeSO4质量浓度继续增加，X3菌株对原油的降解率下降。

| Abstract: | One bacterial strain,designated as X3 which has the capability of degrading crude oil,was isolated from Dagang oil-field.The degradation rate of crude oil is 72.6%.It is identified that the strain X3 belongs to Psedomomas sp.The tests for crude oil degradation by the strain X3 were carried out under shaking-aeration condition.It is found that:Lactose has the effect of promoting the activity of the strain X3,and the degradation rate of crude oil is increased to 80.3%;Glucose and sucrose have the effects of i... |
