Abstract

The matured pediocin PA-1 encoding gene, pedA and its immunity counterpart, pedB from Pediococcus acidilactici K7 were cloned by PCR technique and ligated into the E. coli-lactic shuttle, protein expression vector pAMJ2OO8. The recombinant pAML45 was constructed and sequenced to confirm the intactness of reading frame of the deduced pediocin PA-1 fusion protein. Lactococcus lactis MG1363 was electroporated with the plasmids and the transformation efficiency of ~ 2-3 × 103 μg-1 was observed. This was further confirmed by plasmid DNA isolation and analysis.
