Drug delivery systems (DDSs) incorporating bacterial minicells have been evaluated as a very powerful tool in view of biocompatibility. However, limited studies have been carried out on these systems, mainly using minicells from Salmonella sp. and Escherichia coli. Thus, we generated a new minicell-producing strain from an endotoxin-free Corynebacterium glutamicum by the inactivation of genes related to cell division. The two knockout strains, ${\Delta}parA$ and ${\Delta}ncgl1366$, showed distinct abilities to produce minicells. The resulting minicells were purified via sequential antibiotic treatments and centrifugations, which resulted in reproducible yields.
