Table 3. Practices of directed genetic alterations of LAB.

  • Improved LAB made by introduction of plasmids via the natural event of conjugation or transduction.
  • Improved LAB made by passage (introduction and subsequent elimination) of a recombinant plasmid.
  • Improved LAB constructed by deletions of DNA as a consequence of double cross-over recombination.
  • Improved LAB constructed by self cloning that does not change the total genetic make-up of a LAB cell.
  • Insertion of DNA from micro-organisms with a long tradition of safe use in the food industry.
  • Insertion of DNA from micro-organisms without a long tradition of safe use in the food industry
  • Insertion of DNA from other organisms
