| Abstract: | A soil bacterium, strain no. 19, capable of using unsaturated polysaccharide derived from acidic polysaccharide of Fusarium sp. M7-1 as a sole source of carbon was isolated. The bacterium degraded about 70% of the total sugar content. Results from analysis of the degraded polysaccharide showed that the bacterium degraded the β(1→6) galactofuranoside linkage as well as the unsaturated glucuronic acid residues linked to the galactofuranoside residues via the α(1→2) linkage. |
