Figure 5From: A bacteriocin gene cluster able to enhance plasmid maintenance in Lactococcus lactis Presence of the Lcn972 gene cluster does not allow direct selection of transformants after plasmid electroporation. L. lactis NZ9000 was electroporated with pDorf4 and colony forming units of the transformation mix right after electroporation (generation 0) and during sub-culturing in GM17 were followed by plating in the presence (GM17Em) or absence (GM17) of erythromycin.Back to article page
