Preparation of Xanthan Gum from Xanthomonas campestris cdt1 and cdt2

Abstract

Provided herein is a method of producing xanthan gum from ዉ local isolate of Xanthomonas campestris ርርቪ1. It provides a non-cloned strain, namely Xanthomonas Campestris cdt1, which [5 suitable for efficient fermentation production in the lab and large-scale xanthan gum production. According to the invention, by isolating Xanthomonas Campestris ርርቪ1 and the application method thereof disclosed by the invention, xanthan gum can ከ6 efficiently fermented and produced via steps that may include activation culturing liquid seed culturing,fermentation culturing, and xanthan gum precipitating. The strain disclosed by the invention can be used for efficiently fermenting and producing xanthan gum by taking sucrose and glucose as carbon sources and peptone, yeast extract, ammonium sulfate, and ammonium chloride as nitrogen sources
