• The nifh sequence similarity between isolates t7 and paenibacillus odorifer was 97 % . the 7 isolates with nifli gene were tested for their nitrogenase activity using acetylene reduction assay ( ara ) . isolates c4 , g2 , t7 and w5 showed nitrogenase activity , whereas nitrogenase activity was not detected in the isolates c5 , gl and t1 and suitable conditions for demonstrating nitrogenase activity for them remain to be found
  采用乙炔还原方法对这7个菌株的固氮酶活性进行了测定，其中4个菌株具有固氮酶活性，菌株g2和t7的固氮酶活性相对来讲比较高，分别达到660 . 0nmol乙烯mg蛋白和292 . 5nmol乙烯mg蛋白，但用同样方法却没有测出菌株g1 、 t1和c5的固氮酶活性，它们的最佳固氮条件还有待于发现。
