Abstract

Research on new strains biopolymers have raised the interest of many researchers who study microorganisms with gum production capacity and a higher quality than the existent ones. The present study selected patovars X. campestris pv. manihotis 280-95, X. campestris pv. begoniae 1138-95 and X. campestris pv. dieffenbachiae 1429-00, as best performers, with xanthan gum producing 10,8 g.L-1, 9,0 g.L-1 and 8,5 g.L-1 respectively, being strain 280-95 the best in production and quality. The alkaline stress applied in the process of xanthan gum production of X. campestris pv. manihotis 280-95 increased in 40,76% , deserving more in depth studies to determine the best conditions for the application of the process. Keywords: Xanthomonas campestris. Selection. Xanthan gum. Alkaline stress. Viscosity. Optimization.
