Adaptive acid tolerance response in Lactobacillus acidophilus

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 re...

Description
Summary: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. © Rapid Science Ltd. 1998[PUBLICATION ABSTRACT]
