The method prepares new heteropolysaccharide produced by new Alcaligenes sp.. Thus, YM flask seed is cultured in nutrient broth agar for 48hrs. The seed is inoculated into the medium containing 5g of potassium phosphate, dibasic, 0.1g of magnesium sulfate, 0.9 of ammonium nitrate, 0.5 of promosoy-100, 30 of dextrose, 3% of starch as a carbon source in 1 liter of water. The medium inoculated with the seed is incubated for 72hrs. The culture broth is extracted with 99% of isopropyl alcohol.
