Fermentation feedstock.

摘要

A fermentation process for the production of a product comprising mannose units eg. xanthan gum in which a simple sugar is a component of the fermentation feedstock and a part of that sugar is mannose. Preferably the sugar is a mixture of mannose and glucose optionally containing minor amounts of other sugars, the mixture of mannose and glucose suitably being produced by the epimerisation of glucose.
