Kinetics of Xanthan Gum Fermentation by Xanthomonas campestris—9002

Abstract

Abstract: The relationships between various parameters and the dilution rate were investigated in chemostat culture system.The results showed that the maximum specific growth rate was μmax=0.0215h-1,substrate constant Ks=4.476,yield of the substrate YGmax=0.062g/g and maintenance coefficient m=0.1543g/g•h and the best theory dilution rate,Dm=0.1376h-1.The results of specific growth rate of Xanthan gum,biomass productivity,remanent sugar and viscosity were also studied.

Key words: Xanthan gum , Kinetics , Chemostat culture , Specific growth rate
