Abstract：The conditions and technical procedure on fermentation of xanthan gum in SM fermentor (50000 L) are described. The medium is starch 4%, peptone 0.5%, CaCO3 0.3%, and the conditions are controlled under pH 7, temperature 28 ℃, gas volume 0.8 in earlier phase and 1 in later phase on seed culture volume 10% respectively. Further tests made in 50000 L fermentor show that the viscosity and the
yield of Xanthan gum are 10000 mPa·s and 3% after 72 h,which meets the need of industrial production.
