研究测定了40株细菌菌株发酵液的几丁质酶活性及对北方根结线虫二龄幼虫的作用。
The activities of chitinase and lethal effects on the second juvenile 40 bacteria strains were determined .

对线虫有强致死作用的菌株并不具有较高的几丁质酶活，细菌对北方根结线虫二龄幼虫的致死作用与其分泌的几丁质酶活性的高低相关性不大。
The activities of chitinase for effective and non-effective strains had not much difference , and the strains which were strongly lethal to the juveniles did not have high activity of chitinase .
