脱水休眠小卷蛾斯氏线虫的生化特性研究

STUDIES ON THE BIOCHEMICAL CHARACTERS OF STEINERNEMA CARPOCAPSAE BJ IN ANHYDROBIOSIS

该文报道了脱水休眠小卷蛾斯氏线虫SteinernemacarpocapsaeBJ的生化特性研究。结果表明当水分失去约24%时,线虫就能进入休眠。相对于未处理线虫,脱水休眠线虫酯酶活性降低,总糖和糖原含量分别减少6.37%和6.77%,海藻糖含量升高1.79%,但粗脂肪和肪脂酸含量保持不变。

The biochemical characters of anhydrobiotic entomopathogenic nematode S.carpocapsae BJ were reported in this paper. S.carpocapsae BJ entered into anhydrobiosis when its water content lost about 24% in SB high osmotic solution. The OD of esterase activity reached 0.085,which was a great difference as compared with control at 0.274. The content of carbohydrate, glycogen reduced 6.37% and 6.77% dry wt respectively,the content of trehalose increased 1.79% dry wt as compared with control. There were no changes in total lipid and fatty acids content.
