The mfd mutant exhibits a growth defect in rich medium. Cultures of 630Δerm (○), the mfd mutant (■) and the complemented strain (▲) were cultured in TY (a) or TYG (b) media containing 15 μg/ml thiamphenicol and their growth measured. The 630Δerm and mfd strains contained the plasmid pMTL960 and the complemented strain the plasmid pSEW070
