Nutritional relationships between oral bacteria.

RESUMO
Nutritional relationships were revealed during the coculturing of Bacteroides gingivalis with Wolinella recta and Bacteroides melaninogenicus with W. recta. W. recta produced a substance that stimulated the growth of B. gingivalis and B. melaninogenicus. Characterization by thin-layer chromatography and absorption spectrometry identified the compound as protoheme. Production of large amounts of formate by B. melaninogenicus stimulated the growth of W. recta. These nutritional relationships could represent examples of mechanisms favoring bacterial succession in periodontal sites.
