Medium plays a role in determining expression of acrB, marA, and soxS in Escherichia coli.
Analysis of expression of acrB, marA, and soxS in rich and minimal media, at early and late logarithmic growth phases, showed that acrB had increased expression in minimal medium compared to rich medium, but expression decreased dose dependently upon exposure to ciprofloxacin.
