ABSTRACT:
Increasing the molecular length of xanthan polymer makes a higher viscosity xanthan composition. Xanthan with higher specific viscosity characteristics provides more viscosity at equivalent concentration in food, industrial and oilfield applications. Methods for increasing the viscosity of xanthan include inducing particular key genes and increasing copy number of particular key genes.
