This paper deals with microbial synthesis of xanthan gum by Xanthamonas campestris strains and its applications in various industrial processes. The proposed biosynthetic pathway of xanthan synthesis by X. campestris strains and biotechnological methods of improving xanthan production were discussed. The biotechnological parameters for efficient improvement of xanthan yield and productivity such as agitation rate, pH, temperature and various additives were described. Furthermore, the applications of xanthan gum in the food, pharmaceutical, textile, oil drilling and cosmetic industries were presented.
