Abstract A mutant strain of the genus Xanthomonas produces a pyruvate-free biopolymer. This biopolymer and the deacetylated form of this new biopolymer provide mobility control solutions which are especially useful for enhanced oil recovery where high brine applications are involved. The mobility control solutions of the present invention may be made from whole or filtered fermentation broth containing the pyruvate-free biopolymer its deacetylated form. Alternatively, the biopolymer its deacetylated form may be recovered from the broth and the recovered product used to form the desired mobility control solutions.
