Abstract
Methods for the recombinant-DNA mediated production of xanthan gum and gum variants structurally related to xanthan are disclosed. The methods in part involve the synthesis of these polysaccharides in anaerobic and/or denitrifying hosts. In particular, plasmids pX209 and pRK290-H366 are disclosed which contain the genes, isolated from X. campestris, encoding Transferase I, Transferases II, Transferase III, Transferase IV, Transferase V, Ketalase, Acetylase and Polymerase. These plasmids have been deposited in the American Type Culture Collection under Accession Nos. 67051 and 67049, respectively.
