| 本主苦难对分离自宁夏沙直以头地区的１７株根瘤菌手１６株已知参比菌进行了１６种多位点酶电泳分析。将所得数据做聚类分析表明，分离自沙坡头地区的根瘤菌中，有１２株相似性较高，不同于已知参比菌，而独立成群，这与数值分类结果吻其分类地位需进一步研究确定。 |

| Abstract: |
| Seventeen strains of rhizobia isolated from Shapotou region in Ningxia Autonomous Rogion and 16 reference strains of rhizobium species were analysed by electrophoresis of 16 multilocus enzymes. Based on clustering analysis. There were 12 new isolates differred from the reference strains. This result is in accordance with that of the numerical taxonomy and composed as a separate group at 90% similarity. The elec-trophoretic patterns of isocitrate dehydrogenase (ICDH), 6-phosphogluconate dehydroge-nase (6PG), glucose 6-phosphate dehydrogenase(G6P), xanthine dehydrogenase (XDH),phosphoglucose isomerase (PGI), phosphoglucomutase (PGM) and superoxide dismutase (SOD) were rather useful to classification of rhizobia. |
