摘要：
The strain nature-isolated of Agrobacterium rhizogenes IBB-1601, aerobic bacteria, was cultivated on a medium containing glucose as carbon source and corn steep liquor as nitrogen source, enriched with salts, with aeration and stirring conditions, at 28 degrees C. Curdlan hype polysaccharide was biosynthesized reaching a concentration of 30.7 g/l after 54h fermentation (productivity 0.56g/lh). By processing of the fermentation broth a final product containing 70-88% polysaccharide was obtained. Analytical characterization has revealed a structure of curdlan type. Curdlan is a food additive and potential anti-tumoral agent.
