Figure 1

Flow-cytometric analysis of cellular dehydrogenases of freeze-dried A. senegalensis cells stored at −21°C (A), 4°C (B) and 35°C (C) for 12 months. Thiazole orange (TO) was used to stain all the cells (viable and non-viable cells). CTC is reduced by active cellular dehydrogenases, and the emitted light is absorbed on FL3. The activity of dehydrogenases which determined by CTC reduction was considered as a sign of viability.
