Decreased acid tolerance in dps , recA , and dps recA strains. Acid challenges of parent (◆ ATCC43895), dps (▲ FRIK47992), recA (■ FRIK4704-kcj05), and dps recA (● FRIK4704-kcj06) strains were performed and the percent survival for each strain was monitored over time. Averages of at least three independent trials with standard error of the mean represented by error bars are presented.
