Plasmid DNA in Strains of Pediococcus cerevisiae and Pediococcus pentosaceus.
Five parental strains of Pediococcus were examined for plasmid content. Each strain contained three to six resident plasmids, ranging in size from 4.5 to 39.5 megadaltons. A bacteriocin-like substance produced by Pediococcus cerevisiae FBB63 was tentatively linked to a 10.5-megadalton plasmid after being cured with novobiocin.
