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 isolate having excellent potential.

1. Xanthomonas strain isolated indigenously at BARC has been used for standardization of xanthan gum production.
2. The process involves use of readily available food grade raw material in the production medium for improved production of xanthan gum.
3. An alternate to xanthan gum which is imported from USA, Australia, France and China saving important foreign exchange.
4. Xanthan gum yield (dry weight) of around 30- 35g/L was obtained using a 30L pilot scale fermenter.

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

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 strain indigenously isolated at BARC having excellent potential. Xanthan has been approved by the FDA for use as a food additive without any specific quantity limitations.

2. An alternate to xanthan gum which is imported from USA, Australia and China saving important foreign exchange.
3. A medium is developed using cheap food grade chemicals easily available in the market
4. A pilot scale process using 30L fermenter has been standardized.
