Sh.sonnei S型,R型菌の酵素的性状 第2編 静止菌について

With the use of the standard strains, namely, S type and R type of Sh. sonnei stocked in our laboratory as test bacteria, the author made comparative study on modes of the oxidation of glucose and pyruvate by these bacteria in resting form and obtained the following results. 1. In the case where these bacteria are cultured in the plain agar medium for 18 hours, the complete oxidation of glucose below pyruvate in the case of S type seems to be less smoothly carried out than in the case of R type, and it tends to be more or less anaerobic. 2. Even in the case of still standing culture in fluid medium (bouillon) the complete oxidation below pyruvate in the case of S type likewise is less smoothly carried oat than in the case of R type. 3. As for the pathway between glucose to pyruvate in any method of culture, there is no difference between S type and R type; and it seems that the pathway from glucose to pyruvate is mainly through Embden-Meyerhof pathway.
