为了研究胡卢巴根瘤菌的生理生化特性,通过对10株青海胡卢巴根瘤菌的生理特性试验,结果表明,采自同一地区同一生长时期或不同生长时期的胡卢巴根瘤菌,在生理上有一定的差异,同时表明胡卢巴根瘤菌具有多样化的代谢途径;生化性状试验结果表明,同一地区同一生长时期或不同生长时期的胡卢巴根瘤菌在碳源利用、氮源利用、矿质元素利用等方面均存在差异。
In order to study the physiological and biochemical characteristics of Rhizobium ulmoides, the physiological characteristics of 10 Rhizobium strains were studied. The results showed that Rhizobium mucronatus was isolated from Rhizobium mucronatus in the same region or in different growth stages, There are some differences between the two species. At the same time, Rhizobium versicolor has diversified metabolic pathways. The results of biochemical traits showed that Rhizobium meliloti in the same region or in different growth stages had the greatest difference in carbon source utilization, nitrogen source utilization, There are differences in the use of mineral elements and so on.
