Using a genetically engineered mutant of Staphylococcus aureus alpha-hemolysin to create pores in the cellular membrane, trehalose was successfully loaded into cells. Differential scanning calorimetry was used to study the glass transition temperature in cells containing intracellular trehalose. Results show higher glass transition temperatures and enhanced stability of the cytoplasm due to the presence of trehalose, compared to cells without intracellular trehalose. In addition, initial experiments show that cell survival depends on the glass transition temperature, as well as the storage temperature and the final moisture content.
