✦ Synopsis


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 octasaccharide has the same structural elements as the high-molecular-weight exopolysaccharide and is considered to be the repeating unit of this polysaccharide.

Extensive surveys for the effects of various P-o&cans on the coagulation cascade in horseshoe crab amebocyte lysates showed that low-mol-wt-(1 + 3)-p-o-glucans and laminaran oligosaccharides inhibit the activation of a limulus coagulation factor G by high-mol-wt-(1 + 3)+?-o-glucans. The inhibitory p
