Nucleation of microbiologic calcification by proteolipid.
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.
