Abstract
A novel mixed bacterial culture isolated from soil by enrichment culture techniques produces a xanthanase enzyme complex which is stable to 65.degree. C. in the presence of salt. These properties render the heat-stable, salt-tolerant xanthanase useful for in situ degradation of xanthan gum in petroleum recovery fluids and other thickened industrial brines.
