<human>:  Are vinegar pickled cucumbers rich in lactobacillus?
<bot>: No, vinegar pickled cucumbers are not rich in lactobacillus. Lactobacillus is a genus of bacteria. Pickles made with vinegar are not probiotic and are simply preserved. Pickles made through a soak in a salt brine solution begin to ferment because of lactobacillus. So vinegar pickled cucumbers are not rich in lactobacillus.
