title: Existence of phosphoenolpyruvate: carbohydrate phosphotransferase systems in Lactobacillus fermentum, an obligate heterofermenter.
abstract: The presence or absence of the phosphoenolpyruvate: carbohydrate phosphotransferase system (PTS) in obligately heterofermentative group III lactobacilli including Lactobacillus brevis (3 strains), L. buchneri (2 strains) and L. fermentum (3 strains) was surveyed systematically for a series of sugars utilizable by these organisms. Contrary to common expectation, PTSs were found in two strains of L. fermentum: sucrose-PTS in one strain; sucrose- and mannose-PTSs in the other. All these activities were found to be constitutive.
