Influence of ultrasound on sorbitol release by Zymomonas mobilis grown on high sucrose concentration. Braz. arch. biol. technol. [online]. 2006, vol.49, n.3, pp. 371-374.

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.

Keywords : Zymomonas mobilis; sorbitol [ultrasound].
