Oligosaccharides from porphyran digested by enzymes of <i>Arthrobacter</i> sp. S-22 were purified by Daiya ion HPA-75, Toyopearl HW-40S, and Sephadex G-10 column chromatography. Each of three purified oligosaccharides (high anionic oligosaccharide (OSP1), low anionic oligosaccharide (OSP2), and neutral oligosaccharide (NOSP)) showed a single peak on a Shodex SUGAR KS-801 column, respectively. The structure of OSP1 was considered to be sulphato-disaccharide (6-<i>O</i>-sulphato-α-galactopyranosyl-(1→3)-D-galactopyranose), while OSP2 and NOSP were considered to be mono sulphato-tetrasaccharide and neoagarotetraose.
