Abstract
A novel Bacillus isolated from the soil is unique in its capacity to produce xanthanase, and is especially productive of the enzyme when cultured in the presence of other soil organisms. Both crude and purified xanthanases recovered from the fermentation broth effectively degrade xanthan gum. Moreover, tolerance of the Bacillus to sodium chloride levels as high as about 4%, render it useful for the in situ degradation of the heteropolysaccharide in petroleum recovery fluids and other thickened industrial brines.
