对208株谷氨酸产生菌的分类学特征和代表菌株的DNA碱基组成进行了研究。这些微生物通常为革兰氏阳性、不形成孢子、不活动、椭圆形球形至短多形性杆状，生长需要生物素，并需氧积累大量L-谷氨酸。在这些菌株的生理特性中发现了一些微小的差异。检查的所有菌株都属于棒杆菌属中的单一物种或非常密切相关的物种。它们在生理上可分为12个生物型。DNA的鸟嘌呤+胞嘧啶（G-C）含量可分为3组，Ⅰ、Ⅱ、Ⅲ组，G-C含量分别为53%、56%和65%。
The taxonomic characteristics of 208 strains of glutamic acid-producing bacteria and the base compositions of DNA from representative strains were studied. These organisms are usually gram-positive, non-sporulating non-motile and ellipsoidal spheres to short pleomorphic rods, requiring biotin for growth and accumulating aerobically large amounts of L-glutamic acid. Some minor differences are found in the physiological characteristics of these strains. All strains examined belong to a single species or to very closely related species in genus Corynebacterium. They can be classified biotypes physiologically into 12 types. The guanine plus cytosine (G-C) content of DNA of these strains varied as represented by 3 groups, groups -I, -II and -III, G-C contents of which are 53,56 and 65%, respectively.
