Polysaccharase and particularly combined polysaccharase/protease treatments offer new alternatives for clarifying aqueous xanthan gum dispersions. Each enzyme has its specific action-the proteases on the insoluble residual bacterial cells, and the polysaccharases primarily on the microgels. Preliminary tests of these enzymatic treatments for scheduled field applications show promising improvements in filterability, especially for solutions prepared from xanthan powders.
