Última Influence of ultrasound on sorbitol release by Zymomonas mobilis grown on high sucrose concentration BABT Barros,Márcio de; Celligoi,Maria Antonia P. Colabone; Vignoli,Josiane Alessandra; Vargas,Lucia Helena Mendonça. This work investigated the effect of applying low intensity ultrasound on sorbitol release by Z.mobilis cultures grown on 200 g/L sucrose medium up to 48 h. The best sorbitol production was 36.09 g/L in 36 h culture. Ultrasound irradiation did not alter the sorbitol values detected after disrupting the cells with 20 minutes treatment.

The bacterium Zymomonas mobilis presents potential for sorbitol production when grown in culture medium with high sugar concentration. Sorbitol is produced and accumulated in the periplasma of the bacterium to protect the cells from the harmful effects of high osmotic pressure that results from the action of invertase on sucrose. The conversion of sucrose into glucose and fructose increases the osmolarity of the medium. However, an excessive increase in the osmotic pressure may decrease the sorbitol production. In this work Saccharomyces cerevisiae invertase was added two media containing sucrose 200 and 300 g.L-1. Sorbitol production in sucrose at 200 g.L-1 was 42.35 and 38.42 g.L-1, with and without the invertase treatment, respectively. In the culture...

The production of sorbitol by permeabilized and immobilized cells of Zymomonas mobilis in Luffa cylindrica was investigated in sucrose medium. A full 2³ factorial design was used to verify the influence of each factor and its interactions. The cell permeabilization showed a significant and negative effect upon the production of sorbitol, while the time of cultivation and the immobilization process were significant and positive. The results demonstrated that the cell immobilization and the time of cultivation of 36 h presented higher production of sorbitol.
