Production and rheological characterization of biopolymer of Sphingomonas capsulata ATCC 14666 using conventional and industrial media

Appl Biochem Biotechnol. 2006 Spring:129-132:942-50.

Abstract

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.
