Xanthan gum: A versatile biopolymer for biomedical and technological applications

Xanthan gum is an extracellular polymer produced mainly by the bacterium Xanthomonas campestris . Traditionally it plays an important role in industrial applications as thickener, emulsion stabilizer and it has been added to water‐based drilling fluids due to its pseudoplastic behavior and thermal stability. The structural properties of xanthan in solution can be tuned by the temperature and ionic strength; under high ionic strength or low...
