Soil polysaccharides synthesized during decomposition of glucose and dextran and determined by 14c labeling
1976
WAGNER, GEORGE H.
After treating soil with labeled substrate and incubating for various periods of time, carbohydrates were extracted using several reagents. The C in the extracts was determined and interpretations were made relative to soil polysaccharide synthesis. Microorganisms utilized glucose more rapidly than dextran and polymers of high molecular weight containing C had been synthesized by 2 days in the glucose-treated soil. Soils treated with either substrate showed a significant increase in mannose at 5 days in the high molecular weight of polysaccharides examined. Presumably this was of fungal origin.
