## In addition to cellular glycogen and an acidic exopolysaccharide of high molecular weight, Rhizobium mefifoti (5 strains) produces a cyclic (1+2)-p-D-glucan (d.p. -20) that accumulates in the cells, and a pyruvylated and succinylated octasaccharide that is excreted into the medium. The octasacc

We developed a mutant strain, which showed a higher ␤-glucan production than the parent strain, Agrobacterium sp. ATCC 31750. A batch fermentation was carried out in a 300 l stirred tank reactor. A maximum ␤-glucan concentration of 76 g/l was obtained in 120 h of cultivation with the mutant strain,
