Abstract excerpt

Numerous industrial bacteria generate hydrogen peroxide (H(2)O(2)), which may inhibit the growth of other bacteria in mixed ecosystems. We isolated spontaneous oxidative-stress-resistant (SpOx) Lactococcus lactis mutants by using a natural selection method with milk-adapted strains on dairy culture medium containing H(2)O(2). Three SpOx mutants displayed greater H(2)O(2) resistance. One of them, SpOx3,...
