摘要

Use of yeast biomass as a substrate, supplemented or nu00e7o to produu00c7u00e7o of biopolu00cdmero type xanthan gum.Using the yeast biomass from industrial processes, fermentative, rich in complex carbohydrates and / or simple, in addition to other nutrients, in the form of solids, pastes, liquids.Or other forms, or set of such waste supplemented or not with other nutrients, with strains of Xanthomonas bipolu00edmeros type for the production of xanthan gum.Using aerated and agitated reactors.The invention aims to obtain low cost alternative substrates for fermentation process for the production of polysaccharide type xanthan gum.When compared to the industrial process of bioconversion of sucrose or glucose.This invention involves the optimization of the parameters of the composition of the culture medium with biomass of yeast and the fermentation conditions such as pH, temperature, time and speed of stirring.And the assessment of the need for additional source of nitrogen, phosphorus, potassium, and other nutrients in the substrate fermentation.
