Thirty-one strains of 23 gram-negative oral bacterial species were examined for dextran-degrading activity on agar plates containing blue dextran. One strain each of Capnocytophaga ochracea, Capnocytophaga sputigena, Prevotella loescheii, Prevotella melaninogenica and Prevotella oralis had detectable dextranase activity. The culture supernatants of P… CONTINUE READING
