摘要：

The biosynthesis of xanthan by Xanthomonas campestris was found to be affected by the addition of citric acid in fed batch mode. Under oxygen-limiting conditions, the addition of up to 2.6 g citric acid per litre improved cell viability as well as increasing xanthan yield by up to 80%. Comparative xanthan formation profiles at different operating conditions indicate that at higher aeration (when there was no oxygen limitation), citric acid addition did not improve xanthan production.
