Title: The oral yeast-lactobacillus relationship I. Nonutilization of hexosephosphates by an oral lactobacillus
Abstract: The theory that there is a symbiotic relationship between an oral yeast and an oral lactobacillus as the result of a complementary effect of the enzyme systems of each is based on the premise that the high phosphatase activity of the yeast provides the lactobacillus component of the mixed culture with hexosephosphates. A study was carried out on the utilization by an oral lactobacillus of the hexosephosphates for growth and acid production. The study demonstrated that an intact, viable, metabolizing oral strain of Lactobacillus casei cannot utilize hexophosphates for growth or lactic acid production.
