摘要：

Stationary phase cultures of Lactobacillus acidophilus CRL 639 are naturally acid resistant to pH 3.0 while exponential phase cells induce an acid tolerance response upon exposure to sublethal pH (3.8-6.0). Maximal response was achieved after adaptation at pH 4.2 and pH 5.0. Protein synthesis was required in the latter case.
