摘要

The process of produu00c7u00e7o of xanthan gum by using sucrose and / or glucose and glycerol as carbon source. The present invention relates to a process for the production of xanthan gum by using sucrose and / or glucose and glycerol as carbon source in the culture medium.The origin of the sucrose and / or glucose can be both sucrose and / or glucose as commercial food grade sucrose and / or glucose present in the aqueous extract of pod of mesquite. In the case of the use of aigaroba pod, it is subjected to a pretreatment in order to extract the nutrients of this legume in aqueous solution.The glycerol is added in a concentration of 0.1% to 2% (w / V) to extract mesquite diluted or a culture medium formulated both containing from 0.5 to 4% (w / V) of sucrose and / or glucose. Xanthan gum is then produced by fermentation of the extract of mesquite diluted or the culture medium formulated with added glycerol from the action of the bacterium Xanthomonas sp.
