Study of genetic control of pediocins synthesis

Moscow State University of Applied Biotech­nology; Mechnikov Research Institute of Vaccines and Sera, Moscow, Russia

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.
