ABSTRACT
The Azorhizobium caulinodans isolated from the stem nodules of a leguminous emergent hydrophyte, Aeschynomene aspera, produced a large amount of extracellular polysaccharides (EPS) in yeast extract basal medium. Maximum EPS production was at the stationary phase of growth. EPS production was increased by 919% over control when the medium was supplemented with sucrose (1.5%), D-biotin (1 microgram/ml) and casamino acid (0.1%). EPS contained rhamnose and arabinose. Possible role of the azorhizobial EPS production in the stem nodule symbiosis is discussed.
