Acid-containing Polysaccharides Research Articles

Method for the selection of bacteria that synthesize uronic acid-containing polysaccharides.

Markovitz, Alvin (University of Chicago, Chicago). Method for the selection of bacteria that synthesize uronic acid-containing polysaccharides. J. Bacteriol. 82:436-441. 1961.-A method has been devised for selecting bacteria that synthesize uronic acid-containing polysaccharides from soil samples. The method depends on the addition of high concentrations of SO(4) (=) to a liquid enrichment medium.

Fractionation of pig gastric mucosa and the properties particularly antigenicity of the high-molecular components separated. I.

1. The extract by the aid of physiological saline of pig stomach mucosa was fractioned and two proteins, a pentosenucleic acid and a group carbohydrate were isolated in electrophoretically homogeneous state. Besides, preparations of hexuronic acid-containing polysaccharides (polyuronic acids) were obtained. 2. The properties of the substances yielded were examined. Through the Grant Committee for Scientific Researches was given a grant from the Education Department in aid to us. H. Masamune.
