Temperature effect on dextransucrase production by Leuconostoc mesenteroides FT 045 B isolated from Alcohol and Sugar Mill Plant
Temperature (23 to 31°C) and sucrose concentration (3 and 4%) effects on dextransucrase production by Leuconostoc mesenteroides NRRL B 512 (F) and Leuconostoc mesenteroides FT 045 B were studied. The conditions in all fermentations were: total reaction volume 2 L, 132 rev. min-1, 0.5 vvm and pH 6.0....

| Resumo: | Temperature (23 to 31°C) and sucrose concentration (3 and 4%) effects on dextransucrase production by Leuconostoc mesenteroides NRRL B 512 (F) and Leuconostoc mesenteroides FT 045 B were studied. 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. |
