Xanthan production of the Xanthomonas campestris pv. campestris B100 wild type and the wxcB mutant H21012, the wxcK mutant H28110 and the wxcN mutant H20110. Production was measured as dry weight [g] xanthan per [g] biomass. Samples were harvested from ten replicates each. Harvest was after 96 h within the late stationary phase. Bars give the normalized mean xanthan yields, with error bars indicating the standard deviations
