| Abstrakt: |
Highly viscous polysaccharide (250-350 kDa) of an alginate nature with a predominance of alpha-L-guluronic acid (M/G = 0.22) was obtained from Azotobacter vinelandi. The yield ofpolysaccharide was 20.5 +/- 0.5 g/l when cultured in a medium containing molasses at a viscosity of the cultural liquid of over 30000 cSt. The biopolymer is stable at pH 4.0-9.0 in a wide temperature range and well soluble in highly mineralized water; it retains a high viscosity level and can be used in the petroleum industry for enhanced oil recovery. |
