Abstract: This work studied the biopolymer production by Sphingomonas capsulata ATCC 14666 using industrial raw material and pretreated molasses and aqueous extract of textured soy protein (TSP). Different concentrations of industrial media (2.66, 4, 6 and 8 w/t%) were evaluated at 28° ± 2°C, 208rpm, 72h, were the fermentation conditions utilized. Triplicate assays were conducted and Tukey s test was used. The highest productivity were obtained for 8% of pretreated molasses (0,290 gL-1h-1), 6% of aqueous extract of TSP (0,240 gL-1h-1) and 8% raw molasses (0,190 gL-1h-1), respectively. The rheological behavior of aqueous and saline (NaCl and CaCl2 3% wt/v) solutions of biopolymers were investigated by apparent viscosity analysis at 25 and 60°C.
