Xanthum gum biopolymer shows promise for enhanced oil recovery. One of its major current uses is in drilling muds. After a preliminary review of its characteristics and potential for manufacture by fermentation, a scalable laboratory pilot study was conducted at Marathon Oil Co.'s Denver Research Center to evaluate the suitability of several feedstocks and bacterial organisms. These fermentation results confirm US Department of Agriculture, National Regional Research Laboratory (NRRL), procedures and recommendations for this bacterial fermentation and indicate a number of practical feedstocks for producing high viscosity broths. The research to date on the biopolymer xanthan gum and fermentation broth is summarized. Experimental results indicate that broad ranges of readily available carbohydrate and nitrogen sources are suitable and economical alternative substrates for this fermentation. Dissolved oxygen concentration and oxygen usage are practical parameters for monitoring the fermentation. 16 references.
