Plasmid profiles of L. lactis subsp. lactis BGKP1 Agg+ (Lanes 1, 3, 5 and 7) and BGKP1-20 Agg- derivative (Lanes 2, 4, 6 and 8) analysed on 1% agarose gel. Lanes 1 and 2, non-digested plasmids; Lanes 3 and 4, plasmids digested with EcoRI restriction enzyme; Lanes 5 and 6, plasmids digested with PstI restriction enzyme; Lanes 7 and 8, plasmids digested with SalI restriction enzyme; Lane 9. Gene Ruler DNA size marker (Fermentas, Vilnius, Lithuania). Arrows indicate positions of plasmid bands/fragments present only in L. lactis subsp. lactis BGKP1 Agg+ strain.
