title: Cyclic (1----2)-beta-D-glucans (cyclosophorans) produced by Agrobacterium and Rhizobium species.
abstract: Neutral and acidic cyclic (1----2)-beta-D-glucans (cyclosophorans), obtained from culture filtrates and cells of Agrobacterium and Rhizobiun, are synthesised on the cell surface and then secreted. Eight cyclosophorans with dp 17-24 were isolated; all of the strains of Agrobacterium showed almost the same distribution pattern, whereas there were three other distribution patterns for the strains of Rhizobium.
