To study the incorporation of radioactive phosphorus by Lactobacillus leichmannii growing in media with and without vitamin B12, the cells were grown either in a complete medium (broth plus liver extract) or in a test medium (Skeggs et al.: J. Biol. Chem., 176, 1459, 1948) with a limiting quantity of B12. After 48 hours' growth, the cells were harvested, washed, and resuspended in the test medium containing radioactive phosphorus. One one-hundredth ,ug per ml of B12 was added to one-half of the cells, and the cultures were incubated at 37 C, either with aeration or in 100-ml graduates to give semianaerobic conditions. Twenty-ml samples were withdrawn at intervals for measurements of the growth (by optical density determination), pH, and radioactivity.
