The insoluble material that remains after extraction of Zea shoots with cold buffer was treated successively with 3m LiCl and hot water. The polysaccharides solubilized by these treatments were mostly (1→3),(1→4)-β-d-glucans. The β-d-glucan from the hot-water-soluble fraction was hydrolyzed by Bacillus subtilis (1→3),(1→4)-β-d-glucan 4-glucanohydrolase. The oligosaccharides were characterized by methylation analysis of the enzymic fragments and by methylation analysis of secondary fragments generated by treatment of the isolated oligosaccharides with Streptomyces QM B814 cellulase. The results demonstrate that the native polysaccharide consists mainly of cellotriosyl and cellotetraosyl residues joined by single (1→3) linkages. Evidence is presented to show that certain other glucosyl sequences are also present in the native polysaccharide including (a) two, three, or four contiguous (1→3)-linkages; (b) blocks of more than four (1→4)-linked glucose residues; (c) regions having alternating (1→3)- and (1→4)-linkages.
