Xanthan gum is a polysaccharide secreted by the bacterium Xanthomonas campestris, and is used as a thickener, stabilizer, emulsifier, and rheology modifier in food, cosmetics, oil, and pharma industries. A process has been developed for production of xanthan using a Xanthomonas BARC-laboratory isolat having excellent potential

SALIENT FEATURES OF THE TECHNOLOGY

• Xanthomonas strain isolated indigenously at BARC has been used for standardization of xanthan gum production.
• The process is made highly cost effective modified with the use of cheap agriculture produces in the production medium.
• Radiation depolymerized guar gum has similar viscoelastic properties as commercial enzyme hydrolyzed product.
• An alternate to xanthan gum which is imported from USA, Australia and China saving important foreign exchange.
• Xanthan gum yield (dry weight) of around 30- 40g/L was obtained using a 30L pilot scale fermenter.

APPLICATIONS

• Mainly used in food industry for its thickening, stabilizing, jelling, and emulsifying properties.
• In its nonfood uses, xanthan gum finds application in the preparation of toothpastes, cosmetics, polishes, paints, adhesives, ceramics, and explosives.
• In the petroleum industry, xanthan gum is used for enhanced oil recovery.
