Abstract
Rhizobium hedysari strain HTCN 1 produces viscous fermentation broths due to the presence of exopolysaccharide (EPS) products. Production of these products has been studied by testing a wide range of C- and N-s ources. The highest EPS yield (9.04 g/L) has been obtained after 7 day s cultivation in shaken flask on mannitol and lysine. The isolated and purified EPS has been subjected to chemical identification by means o f NMR and FTIR spectroscopies.
