Studying the potential of xanthan gum production by local bacterial isolate of Iran

Materials and Methods: In this study, xanthan production in a new strain and native of Xanthomonas campestris strain saba.ton and bacterium of X. campestris PTCC 1473.To produce the gum, bacteria after becoming active in YDC Broth and producing have been studied biomass to were transferred Gum (Production Culture). To produce to a sufficient a mount cell dry weight, diluted fermentation medium and centrifuged, the supernatant was removed for isolation of xanthan cell mass deposition, resuspension and isolated by ethanol precipitation of xanthan and xanthan dry weight was determined by centrifugation done.
