Plasmid DNA Profiles in Strains of Lactococcus, Streptococcus, Enterococcus, Leuconostoc, Pediococcus and Lactobacillus
Year: 2001
Type: article
Abstract: The plasmid DNAs profiles in 88 strains of Lactococcus, Streptococcus, Enterococcus, Leuconostoc, Pediococcus and Lactobacillus were investigated. The presence of plasmids in cocci was demonstrated in 9 of 14 Lactococcus strains, 5 of 7 Enterococcus strains, 8 of 10 Leuconostoc strains and 3 of 6 Pediococcus strains, and the number of the distinct plasmid in their strains varied from 2 to 6. However, 3 strains of Streptococcus thermophilus strains were confirmed to be plasmid-free. On the other hand, 13 of 47 investigated strains of Lactobacillus contained plasmid DNAs. The plasmid DNAs in Lactobacillus casei group strains were the common component, however, those in the Lactobacillus acidophilus group strains were observed only in 3 out of 33 strains. The profiles of plasmid DNAs in lactic acid bacteria were diverse and characteristic patterns in each genus were observed.
