FIG. 2.

Resistance of the ΔyafD mutant of SE2472 to egg albumen. Wild-type strain SE2472, the ΔyafD mutant, and vector pRB3-273C- and plasmid pRB3yafD-transformed ΔyafD mutants were incubated with egg albumen at 37°C. The survival of bacteria was determined by plating, and the results were plotted against incubation time. At least three experiments were performed, and the results of a representative experiment performed in triplicate are shown. The error bars indicate standard deviations.
