<p>The present invention presents a method for the aerobic production of Xanthan by bacteria of the genus Xanthomonas citri or Xanthomonas campestries on a solid substrate of potato pulp. In the exemplary embodiment of the method, the potato pulp substrate's pH was adjusted to 7.2 throughout the process. The substrate was used after sterilization and cooling. 24 hours culture of the two isolates identified as Xanthomonas species were inoculated to the autoclaved substrate and incubated for 6 days at 28 degrees Celsius. After incubation, the bacteria are destroyed, the substrate is diluted and the Xanthan is isolated and dried.</p> |
