The conditions in all fermentations were: total reaction volume 2 L, 132 rev. min-1, 0.5 vvm and pH 6.0. The optimum temperature for enzyme yield for strain NRRL B 512 (F) was 23°C, where at 8-h fermentation was possible to achieve 49.3 DSU/mL. When FT 045 B strain was utilized, 3.2 DSU/mL was obtained at temperature 23 to 25 °C. © 2005 Academic Journals.279-285engDextranDextransucraseEnzyme activityLeuconostoc mesenteroides FT045 BLeuconostoc mesenteroides NRRL B512 (F)TemperatureArtigo2-s2.0-19344363145
