We found that water used to boil sugar cane<br>residue was contained sugar and we thought that this might be used as a raw material to produce other<br>products. Xanthan gum is a polysaccharide that is used as an additive to increase the viscosity and stability of<br>food product and other products. Some micro-organisms could produce xanthan gum. This project focused on<br>the xanthan gum production by using sugar cane residue extraction as raw material, and Xanthomonas<br>campestris TISTR 840. We found that the incubation time of Xanthomonas campestris TISTR 840 at room<br>temperature was 48 hours. Sugar cane residue extraction with a sugar concentration of 1.5g/100 mL and pH 7,<br>incubated with Xanthomonas campestris TISTR 840 for 144 hours at room temperature and 200 rpm shaker<br>speed could produce xanthan gum in highest amount, 1.5% yield. Addition of KCl at 4 g per 100 mL of<br>incubation media removed the micro-organism. We dried xanthan gum for 30 minutes at 1000 C and collected<br>1.5 g of xanthan gum. The produced xanthan gum was soluble in water, 95% ethanol, 5% NaOH, 8% HCl,<br>isopropyl alcohol and glycerol. It was stable in 5% NaOH, 8% HCl and 2% NaCl. The produced xanthan<br>gum was soluble in water at a concentration of 2 g/100mL and was stable at 1200C. Infrared spectroscopy<br>showed that both produced and commercial xanthan gum had a similar IR spectrum. The results indicated<br>that xanthan gum could be produced from agricultural waste.<br><br></p> ER -
