O livares , J., B edmar , E.J. & M artinez ‐M olina , E. 1984. Infectivity of Rhizobium meliloti as affected by extracellular polysaccharides. Journal of Applied Bacteriology 56 , 389–393. The addition of crude extracellular polysaccharide (EPS) preparations from highly infective Rhizobium meliloti increased the infectivity of a poorly infective strain. The addition of crude EPS preparations from another species did not promote nodu‐lation, suggesting the specificity of such an effect. Acid treatment of the crude EPS preparations resulted in total inhibition of nodulation.
