A method of increasing xanthan gum production, comprising culturing a Xanthomonas campestris strain having a xanthan-increasing modification in a culture medium, wherein the modification is selected from the group consisting of (1) a mutation causing rifampicin-resistance; (2) a mutation causing bacitracin-resistance; or (3) exogenous genetic information controlling the synthesis of xanthan; and separating xanthan from the culture medium, is provided along with specific DNA sequences and Xanthomonas campestris strains showing increased xanthan gum production.
