Degradation of glucose-1-C14 and a possible new step in the mechanism of fermentation

The availability of glucose-1-c14 has permitted the verification of a scheme of glucose degradation applied to sugars formed in photosynthesis to determine the distribution of isotopic carbon within the sugar. As a result of the present investigation, there appears to be a second, though minor, pathway of fermentation of the test organism, Lactobacillus casei
