Basic Biological SciencesComparison of Calcification Between Bacterionema matruchotii and Actinomyces naeslundiiWilford Hall, USAF Medical Center, SGDT, Lackland Air Force Base, San Antonio, Texas 78236
Department of Microbiology and Dental Science Institute, University of Texas Dental Branch, P.O. Box 20068, Houston, Texas 77025 The purpose of this research was to examine the requirements for proteolipid initiation of calcification in culture. Proteolipid from a calcifiable microorganism, Bacterionema matruchotii, was compared with proteolipid isolated from a non-calcifiable microorganism, Actinomyces naeslundii. Although A. naeslundii does not calcify in culture, lyophilized cells and proteolipid-containing extracts do initiate apatite formation. A. naeslundii proteolipid (ANN) differs from B. matruchotii (BMN) in concentration, apoprotein polarity, and phospholipid composition. These differences may alter the ability of ANN to nucleate apatite in the intact cell.
