The Homofermentative Lactobacilli of Apple Juice

SUMMARY : Three species of homofermentative lactobacilli, identified as Lactobacillus delbrueckii, L. plantarum and L. leichmannii have been found to be of widespread occurrence on apples and in the expressed juice. Precautions must be taken to arrest their development during the processing of apples intended for the production of unfermented apple juice, otherwise the juice will be rendered unpalatable through development of excess acidity.
