1. The action of the O enzyme from B. fulminans (Iseki and Masaki) upon the Group O and AO substances from pig stomach mucus was inhibited undoubtedly by L-fucose.
2. The enzyme decomposed galactosamine slightly.
3. The enzyme destroyed Group O activity of the Group O and AO mucopolysaccharides, with cleaving off of about 2/3 and 1/2 respectively of L-fucose, deprivation of rotatory power and decrease of glucosamine/ galactosamine ratio. The undialyzable digestion products used more iodine than the respective substrates.
