| Abstract | ||
| This study included the isolation and identification of Bacillus sp. from the soil, production of polysaccharide from sugar beet molasses as a nutrient medium and from a standard medium was compared. Production of polysaccharide from molasses medium exceeded that produced from the standard medium, since the highest production from molasses was 3.53 g/l after 7 days . The effect of different molasses concentration and nitrogen sources on the growth and the production of extra cellular polysacchaide the highest production was 3.80 and 4.10 g/l which achived in molasses concentration 12% and in ammonium sulphate as a carbon and nitrgen source, respectively. | ||
