Effect of Different Carbon and Nitrogen Sources on the Production of Xanthan by Xanthomonas campestris ATCC 13951.

Xanthan production by Xanthomonas Campestris ATCC 13951 was studied in a basal medium containing various carbon and nitrogen sources. The greatent yeild of Xanthan was achieved with sucrose and sodium nitrate as carbon and nitrogen sources respectively. The yeild of Xanthan was abtained with lactose and sodium nitrite.Regarding the optimum comcentrations of both sucrose and sodium nitrate, 7.5% and .124% respectivly gave the highest production of Xanthan.
