| Abstract | ||
| An extracellular hetropolysaccharide was obtained from the fungus Alternaria alternata isolated locally from tomato fruits using a synthetic medium and certain cultural conditions. The fungus produced (4.99 gm) Polysaccharide and (5,87 gm) biomass per liter of the medium after (8 days) of incubation in shaken cultures. Studying of the physical. Chemical properties and chemical composition of the Polysaccharide was achieved using periodate oxidation and complete smith degradation with application of descending paper chromatography technique. The results showed that the fundimental units were glucose, galactose and mannose, also the presence of β(1- 3)and β(1-6) glycosidic linkages. | ||
