摘　　要：用电子自旋共振(ESR)方法对液体培养的大豆根瘤菌1132—2的完整细胞在常温下进行了测量,并得到了g=2.0024的自由基信号.该信号的强度随菌的培养时间而改变,培养的菌处在对数生长期的信号最大.Electron spin resonance (ESR) spectroscopic measurements have been performed on the free living cells of Rhizobium japonicum liquid cultured in Vitro. The results show that an ESR singnal with g = 2.0024 was observed in aqueous samples of the intact cells. The signal intensities changed according to different phases of the population cultures and the maximum was obtained in the exponential phases of cultures.
