The high final acidity of sauerkraut is produced chiefly by

  • A.Leuconostoc mesenteroides
  • B.Rhodotorula species
  • C.Bacillus subtilis
  • D.Lactobacillus plantarum

Answer: D

Lactobacillus plantarum is homofermentative and considerably more acid tolerant, so it continues working long after Leuconostoc has stopped and carries the acidity to its final level. Rhodotorula is a spoilage yeast and Bacillus has no part in a sound fermentation.
