Ten Bacteroides species found in the human colon were surveyed for their ability to ferment mucins and plant polysaccharides ("dietary fiber"). A number of strains fermented mucopolysaccharides (heparin, hyaluronate, and chondroitin sulfate) and ovomucoid. Only 3 of the 188 strains tested fermented beef submaxillary mucin, and none fermented porcine gastric mucin. Many of the Bacteroides strain...

The stability of type 2 dengue virus to exposure to a variety of laboratory conditions was determined. Suckling mouse brain passage virus was adapted for growth in BHK-21 cells, and plaque assays were performed using a tragacanth gum overlay. A three- to fourfold increase in plaque size could be obtained if monolayers were subconfluent at time of inoculation. Incubation of virus for 24 h at 37 ...

The present study deals with isolation of different polysaccharides from Plantago Ovata husk and their use in designing the controlled release Gastro-Retentive (GR) floats of piroxicam (PRC). Gastroretentive floats are actually drug release (DR) moieties of low density used to retain the drug in stomach for maximum time to increase its bioavailability. The polysaccharides extracted from P. Ovat...

The unique attributes, biodegradability, biocompatibility, perfect accessibility, and low production costs led to the use of natural gums in a different section our lives. Among them, we can mention obtained from microorganisms (xanthan gum gellan gum), plant tissues (Arabic tragacanth), seeds (konjac guar seaweeds (alginates, agar gum, carrageenans). Gums have essential applications medical ph...

It generally is accepted that a diet high in fiber, decreased dietary fat content were present. Thus, it has not been possible to determine if dietary fiber was patticularly soluble fiber, is useful in the management playing a significant role. The of studies in of the plasma glucose concentration in individuals with diabetes. This is one of the reasons several which specific, defined fibers ha...

we introduce a new smooth, non-toxic, biocompatible method for cross-linking of gum tragacanth (gt), a polysaccharide of natural origin, in order to serve as a new supporting matrix for immobilization systems.  the modified gum is used as a matrix for the catalysis of the conversion of benzyl penicillin to 6-aminopenicillanic acid (6-apa) by means of escherichia coli atcc11105 with penicillin g...
