FIG. 1.

Utilization of protein as the sole carbon and nitrogen source for growth of wild-type P. aeruginosa KU2 and the lepA mutant. (A) Growth in albumin medium. (B) Growth in hemoglobin medium. The growth rate of each P. aeruginosa strain was monitored sequentially by measuring the optical density at 600 nm. Values represent the mean results from duplicate determinations. The data from a representative experiment are presented, and similar results were obtained in three independent experiments.
