Figure 4From: Functions of the Clostridium acetobutylicium FabF and FabZ proteins in unsaturated fatty acid biosynthesisGrowth of E. coli fabZ mutant strain HW7 carrying plasmid pHW22 encoding C. acetobutylicium fabZ. The plates were of RB medium ei ther unsupplemented or supplemented with the inducer, L-arabinose, or supplemented with the anti-inducer, D-fucose, as shown. The plates were incubated at 30°C. Strain DY330 has the wild type fabZ locus whereas strain HW7 is ΔfabZ.Back to article page
