Mucin desulfation is believed to be a rate-limiting step in mucin degradation by colon bacteria. The activities of enzymes hydrolysing nine linkages found in mucin oligosaccharide chains were measured using model substrates, in extracts of two mucin-degrading bacteria, Prevotella strain RS2 and Bacteroides fragilis. Sulfatases desulfating N-acetylglucosamine-6-sulfate, galactose-6-sulfate and g...
Aiming to assess the presence of selected anaerobic microorganisms in root canals of human teeth with chronic apical periodontitis. 25 central and lateral upper incisors presenting with radiographic evidence of chronic apical periodontitis were studied. The pulp chamber was opened under aseptic conditions and samples of the root canal content were collected with sterile absorbent paper points, ...
Fast food is becoming increasing popular as a social phenomenon, and it usually contains high fat contents. Matcha one versatile tea, its application in brings lots of new consumers. Herein, high-fat diet containing matcha was prepared, this study we investigated the effects such on lipid metabolism intestinal flora normal diabetic mice. Results showed that diabetes had significant weight loss,...
Available tools for genetic analysis in the anaerobic rumen bacterium Prevotella bryantii are limited to only two known systems for gene delivery, and no genes, with the exception of plasmid maintenance and selection genes, have been successfully expressed from plasmids in any species of the genus Prevotella until now. It is shown here that nucB, a newly cloned nuclease gene from P. bryantii, c...
