Lactococcus lactis

◐ Food-origin
Sequenced
Public genome assembly available

Lactococcus lactis is a lactic acid bacterium widely used in dairy fermentation — particularly in cheese and butter production — with a long history of use in fermented foods. No strain-specific clinical or laboratory evidence is indexed for this entry. At the species level, L. lactis has been explored in research contexts as a vehicle for delivering proteins or therapeutic molecules to the gut, but these investigations are experimental and do not constitute evidence of probiotic benefit in the general sense. Strain-specific data would be needed to characterize any particular isolate's properties. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
