Abstract

Markovitz, Alvin (University of Chicago, Chicago, Ill.) and Susan Sylvan . Effect of sodium sulfate and magnesium sulfate on heteropolysaccharide synthesis in gram-negative soil bacteria. J. Bacteriol. 83: 483–489. 1962.—The effect of Na 2 SO 4 and MgSO 4 on heteropolysaccharide biosynthesis has been investigated in gram-negative bacteria isolated from soil. These bacteria may be divided into three arbitrary groups on the basis of the effect of Na 2 SO 4 and MgSO 4 on heteropolysaccharide synthesis: group 1 , synthesis of polysaccharides containing uronic acid is inhibited by increasing the concentration of sulfate ion; group 2 , synthesis of polysaccharides containing uronic acid is stimulated by sulfate ions; group 3 , synthesis of polysaccharide not containing uronic acid is stimulated minimally by Na 2 SO 4 .
