In order to facilitate genetic engineering in amino-acid producing bacteria we have isolated two restriction-deficient Brevibacterium lactofermentum strains. They have been selected for their ability to obtain a high yield of plaques from CL31 phage which was grown on Corynebacterium lilium. These mutant strains do not restrict either phage DNA by transfection or DNA from the shuttle vector pBLA extracted from Escherichia coli by protoplast transformation. These mutants have also lost modification activity. We also report the presence of a restriction modification system in C. lilium ATCC 15990.
