Figure 4From: The role of protein modifications in senescence of freeze-dried Acetobacter senegalensis during storage Auto fluorescence feature of freeze-dried A. senegalensis kept at different storage temperatures for 12 months. Light emitted from cells was collected and appeared on FL3. A significant difference (p < 0.05) was observed between the light intensity mean of cells kept at 35°C and the light intensity mean of cells stored at −21 or 4°C.Back to article page
