The organism that initiates sauerkraut fermentation is

  • A.Saccharomyces cerevisiae of bread
  • B.Leuconostoc mesenteroides
  • C.Lactobacillus plantarum
  • D.Acetobacter aceti of vinegar

Answer: B

Leuconostoc mesenteroides grows first because it tolerates the salt and starts at the near-neutral pH of fresh cabbage juice. It is also the least acid tolerant of the group, so it stops once its own acid has accumulated and hands the fermentation on.
