Lactobacilli Causing Spoilage of Acetic Acid Preserves

Twentyseven cultures of lactobacilli, isolated from 27 packs of spoiled vinegar preserves, which originated from 21 manufacturers and included 12 varieties of product, were examined according to the system of Rogosa & Sharpe and by other tests. One culture conformed to the characteristics of Lactobacillus casei var. casei ; 2 cultures to those of L. brevis ; 4 cultures to those of L. buchneri ; and 20 to those of L. fructivorans. On the basis of the results and an examination of the literature it is suggested that L. trichodes is a synonym of L. fructivorans.
