Abstract : ABSTRACT To produce polysaccharide from Rhizobium meliloti standard medium and can molasses medium were used. Maximal production was achieved in the standard madium, which contains the following compostion per liter: glucose 30 g, (NH4)2HPO4 1.5 g, KH2PO4 0.5 g, MgSO4.7H2O 0.5 g, yeast extract 1.0 g and molasses medium which contains 32 g/l total sugars achieved the maximum production of polysaccharide. The optimum pH, production time, agitation for both of the two media were 6.8, 120 h and 120strokes/min respectively. The incubation temperature was 30°C. The optimum carbon to nitrogen ratio of standard medium and molasses medium were 27.27 and 20.6. At these cultural conditions, Rhizobium meliloti produced 14.12 g/l of polysaccharide in standard medium and 22.04 g/l in molasses medium. The viscosity of these media were 2.37 m Pa.s and 5.78 m Pa.s at shear rate 729 sec-1.
