Industrial Xanthan: Colony Gums

Industrial Xanthan

Xanthan Gum is produced by fermentation, using a pure culture strain of Xanthomonas Campestris with glucose and related chemicals as substrates, followed by purification and recovery with an alcohol solvent. Xanthan Gum consists of repeated pentassaccharide units to form cellulosic backbone through the 1, 4B–D glucosidic linkage and a side chain. The strain of Xanthomonas Campestris is normally stored as freeze-dried ampoules. To activite a biological effect it is inoculated with a nutrient source under essential conditions; prepared inoculums are ready for large-scale fermentation.
