The component of crude phospholipid responsible for B. matruchotii calcification was isolated. Crude phospholipid, extracted from the microorganism, was separated into five fractions by column chromatography. A single, protein-containing fraction catalyzed apatite formation in a metastable calcium phosphate solution. The nucleating fraction was identified as a proteolipid.
