Synthetic Medium for Calcification of Bacterionema matruchotii

A synthetic medium was developed for further study of intracellular calcification by Bacterionema matruchotii. The medium contained metastable calcium phosphate, six other salts, three purines, two pyrimidines, nine vitamins, pimelic and thioctic acids, vitamin-free casein hydrolysate, and glucose. The vehicle was 0.1 M N-tris (hydroxymethyl) methyl-2-aminoethanesulfonic acid buffer at pH 7.4.
