Comparison of culturability in solid and liquid media with reduced activity of 3-oxoacyl-ACP synthase of E. coli and B. subtilis. (a) The c.f.u. and MPN of E. coli MG1655 were determined after incubation at 37 °C for 3 days in M9CAGlc-based solid and liquid media containing various concentrations of cerulenin as indicated. (b) The c.f.u. and MPN of B. subtilis 168 were determined after incubation at 37 °C for 8 days in SPMMCAGlc-based solid and liquid media containing various concentrations of cerulenin. Each experiment was performed in triplicate, and the error bars indicate standard deviations.
