From: Role of a Fur homolog in iron metabolism in Nitrosomonas europaea
Growth curves of the N. europaea wild type (solid lines, filled symbols) and fur:kanP mutant (dotted lines, open symbols) as measured by OD. (A) Fe-replete (squares) and Fe-limited (triangles) medium. (B) 500 μM Fe medium (circles) and in Fe-limited medium with 10 μM ferrioxamine (diamonds). Data shown are means of triplicates, with variation less than 10%. The experiment was repeated several times and produced similar results. Error bars represent the standard error of the mean.
