In this study, a two-plasmid system for enhanced and consistent biosynthesis of the model lactococcal bacteriocin lactococcin A in non-producing Lactococcus lactis hosts was developed. The system comprised a plasmid carrying the genes lcnA and lciA under the control of the nisin-inducible nisA promoter, and a second plasmid harbouring the lcnC and lcnD genes. The introduction of both plasmids into two strains containing the nisRK genes required for nisin-controlled expression, Lc. lactis FI5876 (a nisin A-producer strain) and FI7847, resulted in production of extracellular lactococcin A at a higher level than that for the parental strain, Lc. lactis WM4. In addition, transformation of the nisin-producing host with both plasmids led to a high-level production of both lactococcal bacteriocins, which may provide a means to exploit their complementary properties in cheese ripening.
