Abstract The fragmentation of the biologically active 1,3;1,6-beta-D-glucan Antivir by endo-1,3-beta-D-glucanase LIV from crystalline styles of the marine mollusk Spisula sachalinensis was carried out. It was found that low molecular mass oligomers possessing a stabilizing effect on membranes and anti-viral activity against tobacco mosaic virus appeared in the process of enzymatic hydrolysis of Antivir. Biological activity of 1,3;1,6-beta-D-glucooligo- and polysaccharides was found to be associated with molecular mass (polymerization degree (n) not less than 14) and with presence of intralinked beta-1,6-connected monosaccharide residues. Probably, decrease in molecular mass is compensated by increase in number of intralinked beta-1,6-connected monosaccharide residues.
