Growth of wild type MR-1 and the fur mutant strains at pH 5.5 and 7.0. Cells grown to mid-logarithmic phase were diluted 1/100 in fresh pH-buffered LB media. Growth was monitored every thirty minutes for two days. Three replicates were used for S. oneidensis. The average growth and error bars are shown.
