[Study of genetic control of pediocins synthesis]
Abstract:
Plasmid profiles of 2 strains of Pediococcus acidilactici and 3 strains of P. pentosaceus were studied. Synthesis of bacteriocins in 2 strains of P. acidilactici was coded on the plasmid which was confirmed by experiment with elimination of plasmids and subsequent electrophoregram, which demonstrated synchronous disappearance of bacteriocins synthesis characteristic in plasmid-lacking variants. In 3 strains of P. pentosaceus plasmids were not found which points to chromosomal localization of genes for bacteriocins production.
