Abstract:
A polysaccharide RON substance which has antitumor activity can be produced by fermenting sucrose with a synthetase. The synthetase can be isolated from Leuconostoc strains. Preferred strains of the microorganism are Leuconostoc mesenteroides FERM BP-2242, 2711, 2712, 2713, 2714, and 2670. The substance exhibits antitumor activity against syngenic tumor Meth A, a transplantable tumor in mice.
