Abstract
Xanthan gum is a extracellular polysaccharide produced from aerobic fermentation by bacteria Xanthomonas campestris. Xanthan gum is a commercial product widely used for industrial purposes and in Indonesian its availability is still fulfilled through imports. One of the local microbes that have the potential to produce xanthan gum is a bacterial isolate Xh.C isolated from cauliflower leaf with black rot symptoms.The bacterial isolate Xh.C has a strong character which is belong to the genus Xanthomonas. Xanthan gum production was influenced by several factors, including the need of carbon source, inoculum concentration, and agitation factor. The carbon source can be obtained from industrial waste, one of them is tofu dregs flour. The research was aimed to determine the optimum production of xanthan gum by bacterial isolate Xh.C in fermentation medium with tofu dregs flouras carbon source. In this study we tested the effect of concentration of tofu dregs flour (1, 2, 3, and 4%), inoculum concentrations (3, 5 and 7%) and agitation factor on xanthan gum production. The optimum production of xanthan gum is characterized by the highest number of xanthan gum produced. The optimum xanthan gum production that was reached by 5% inoculum concentration is 19 g/L, using 1% tofu dregs flour and the agitation factor is 150 rpm for fermentation.
