Assimilation of iron via aerobactin by Escherichia coli requires functions encoded by certain ColV plasmids and by the chromosomal fhu region. Mutants obtained by insertion of the transposons Mu d1 (Ap lac) and Tn5 into ColV-K311 revealed that the aerobactin genes are transcribed from the locus that

With the lac operon fusion technique, mutants were isolated in two genes that specify two outer membrane proteins designated FhuE (76 K) and Fiu (83 K). The synthesis of both proteins was increased under low iron growth conditions. The FhuE-protein was shown to be necessary for iron uptake via copro
## Abstract Overflow metabolism is an undesirable characteristic of aerobic cultures of __Escherichia coli__. It results from elevated glucose consumption rates that cause a high substrate conversion to acetate, severely affecting cell physiology and bioprocess performance. Such phenomenon typicall
