Characterization of the response to low pH of Lactobacillus casei ΔRR12, a mutant strain with low D-alanylation activity and sensitivity to low pH.

Abstract excerpt

AIMS: To identify the differences that account for the acid sensitivity of Lactobacillus casei ΔRR12. RR12 controls the expression of the dlt operon, and its inactivation leads to a diminished teichoic acid D-alanylation activity. To this end, a comparison of its response of ΔRR12 to low pH with the parental strain Lact. casei BL23 was carried out. METHODS AND RESULTS: The ability to induce an acid tolerance...
