Identification, separation, and preliminary characterization of invertase and beta-galactosidase in Actinomyces viscosus.
The initial step of disaccharide dissimilation by Actinomyces viscosus serotype 2 strain M-100 was studied. Sucrase activity was found in the 3,000 X g particulate fraction and the 37,000 X g soluble fraction of the cells, whereas lactase activity was found almost exclusively in the 37,000 X g soluble fraction. Neither sucrase nor lactase activity was appreciable in the culture liquor. Sucrose ...

متن کاملRegulation of invertase of Actinomyces viscosus.
The regulation of diethylaminoethyl-partially purified invertase (EC 3.2.1.26; beta-D-fructofuranoside fructohydrolase) from the 37,000 X g-soluble intracellular fluid of Actinomyces viscosus serotype 2 strain M-100 was studied. Glycolytic intermediates, mono-, di-, and triphosphate nucleotides, inorganic phosphate, and various divalent cations were tested for regulatory effects. Fructose-6-pho...
متن کاملIdentification of Actinomyces viscosus from canine infections.
Actinomyces viscosus is a gram-positive, non-acid-fact, facultative, catalase-positive, filamentous, or diphtheroidal microorganism. It was isolated from six canine infections during a period of 1.5 years. The organism was cultured from exudate and flaky granules aspirated from infectious granulomas and empyemas. All cultures grew well aerobically and anaerobically with the addition of 10% carb...
متن کاملMannose-contaminating agglutinin for Actinomyces viscosus and Actinomyces naeslundii.
Rapid agglutination of Actinomyces viscosus and Actinomyces naeslundii cells by D-mannose solutions was observed during studies of their attachment to mammalian cells in vitro. The specificity of the agglutination reaction was studied by slide agglutination tests and by measuring the rate of decrease in optical density of bacterial phosphate buffer suspensions caused by the setting of bacterial...
