Abstract Succinoglycan production by Agrobacterium tumefaciens was increased from 9.5 g/l to 14 g/l when the microorganism was cultivated under fed-batch condition, as compared to batch fermentation. Cells and broth impurities were removed from the fermentation broth with activated charcoal at a temperature of 90 °C, yielding a clear and odorless solution of the polymer. Viscosity mesurement, NMR spectroscopy and Mw determination proved that the polymer retains its main features, practically unaffected by the heat treatment.
