Physiological characteristics, DNA base composition (% GC) and DNA-DNA reassociation values were determined for 138 Lactobacillus acidophilus strains. Twenty seven strains were received from various culture collections and 111 strains were freshly isolated during a study on the composition of the intestinal lactic microflora of piglets and suckling calves. All strains had physiological characteristics which were substantially similar. The strains isolated from pigs were unable to ferment trehalose. The % GC ranged from 35.8 to 43.4. On the basis of the results of DNA-DNA hybridization the strains were divided into four genetic groups.
测定了138株嗜酸乳杆菌的生理特性、DNA碱基组成（%GC）和DNA-DNA重结合值。27株菌来自不同的菌种保藏机构，111株菌是在一项关于仔猪和哺乳犊牛肠道乳酸微生物区系组成的研究中新鲜分离得到的。所有菌株的生理特性基本相似。从猪分离的菌株不能发酵海藻糖。%GC范围为35.8至43.4。根据DNA-DNA杂交结果，这些菌株被分为四个遗传组。
