ABSTRACT:
Fermentation broths and other aqueous suspensions containing a dissolved xanthan gum and suspended solids resulting from the fermentation producing the xanthan gum are clarified by treatment with a minor amount of a protease enzyme. The injectivity of aqueous solutions containing xanthan gum so clarified is improved, in oil well flooding operations, over solutions not so treated.
