Lacto refers to lactic acid. All fruits and vegetables have beneficial bacteria (Lactobacillus) on the surface. In an oxygen-free environment, these bacteria convert sugars into lactic acid, which inhibits harmful bacteria and acts as a preservative. That's why we want our cucumbers to be completely submerged, so they’re in an oxygen-free environment.
