Fast-growing Rhizobium and Agrobacterium strans were studied for their behaviour towards two carbohydrates (glucose and fructose) according to the following criteria: acidification and soluble exopolysaccharide production by resting cells. R. meliloti and Agrobacterium spp. showed a similar behaviour: in glucose-containing medium, acidification occurred and few exopolysaccharides were produced, whereas in medium supplemented with fructose, a neutral pH was maintained and large amounts of exopolysaccharides were synthesized. Other fast-growing Rhizobium spp. did not acidify these media and produced variable amounts of exopolysacchrides.
根据以下标准，对快速生长的根瘤菌和农杆菌菌株针对两种碳水化合物（葡萄糖和果糖）的行为进行了研究：静止细胞的酸化作用和可溶性胞外多糖的产生。苜蓿根瘤菌和农杆菌属表现出相似的行为：在含葡萄糖的培养基中，发生了酸化作用，并且产生的胞外多糖很少，而在添加果糖的培养基中，pH保持中性，并且合成了大量的胞外多糖。其他快速生长的根瘤菌属不会使这些培养基酸化，并且产生的胞外多糖数量各不相同。
