Production and rheological characterization of biopolymer of Sphingomonas capsulata ATCC 14666 using conventional and industrial media.
This work was aimed at the production and rheological characterization of biopolymer by Sphingomonas capsulata ATCC 14666, using conventional and industrial media. The productivity reached the maximum of 0.038 g/L x h, at 208 rpm and 4% (w/v) of sucrose. For this condition, different concentrations of industrial medium were tested (2.66, 4, 6, and 8%). The best productivity was obtained using pretreated molasses 8% (w/v) (0.296 g/L x h), residue of textured soybean protein 6% (wt/v) (0.244 g/L x h) and crude molasses 8% (w/v) (0.192 g/L x h), respectively. Apparent viscosity presented similar results when compared with those in the literature for other biopolymers.
