Acid adapted cells and those grown in non-acidified BHI were
more resistant to a lethal pH than their non-acid adapted counterparts
at the four incubation temperatures assayed, although the
degree of acid tolerance acquired by non-acidified cells was lower
than that found for acid adapted cells, especially at the lowest
temperature tested. Whereas the growth of S. typhimurium in nonacidified
BHI within the temperature range 25–45 C increased its
acid tolerance to about 2.5 times, this increase only represented
about 1.5 times at 10 C. Acid adapted cultures at 10 Table 2 C showed
