Is barotolerance inducible by preincubation under hydrostatic pressure , cold- , osmotic- and acid-stress conditions in Lactobacillus sanfranciscensis DSM 20451T? Context: This study addresses the inducibility of barotolerance by preincubation of Lactobacillus sanfranciscensis DSM 20451T under various sublethal stress conditions. Stress conditions which reduce the growth rate of L. sanfranciscensis DSM 20451T to 10% of its maximum were determined. These conditions were met at 43, 12.5 degrees C, a pH value of 3.7, 1.9% NaCl, or 80 MPa respectively. In contrast to heat preincubation, other prestresses, including salt, cold and pressure led to an increase of barotolerance by hydrostatic pressure of 300 MPa for 30 min. Stationary-phase cells also showed an increased barotolerance. Sublethal pressure leads to enhanced heat tolerance.

Stress response to salt, low temperature and acidic pH as well as starvation overlap with that one to high pressure by inducing barotolerance. Final Decision: yes
