The xanthan gums, produced from the alternative medium SSAE using three different strains of Xanthomonas campestris,gave K and n values typical of pseudoplastic fluids. The native strain 1182 showed the best performance with respect to the K and n values, the percentage of substrate used, and the viscosity.

The agitation of pseudoplastic fluids results in the formation of a well mixed region (cavern) around the impeller and essentially stagnant and/or slow moving fluids elsewhere in the vessel.
