title: Effect of citric acid on the biosynthesis and composition of xanthan.
abstract: The effect of citric acid metabolism by Xanthomonas campestris on composition of xanthan has been studied. Citric acid consumption in fed-batch and continuous fermentation increased the pyruvic acid content of xanthan. An increase in pyruvic acid content in xanthan has been explained with the help of energy balance in xanthan biosynthesis.
