ABSTRACT:
A process of producing xanthan gum using a Xanthomonas microorganism is provided. Increased yields of xanthan gum are obtained by using mannose as part of the carbohydrate component of the fermentation feedstock. Preferably, the carbohydrate component of the feedstock is a mixture of mannose and glucose. More preferable is a mixture comprising 5 to 60% by weight mannose, particularly 20 to 45% by weight mannose, the balance being glucose although minor amounts of other sugars, e.g. maltose, may also be present. The carbohydrate component of the feedstock may be in the form of a raffinate stream from a glucose epimerization.
