Résumé

This study is aimed at evaluating the performance of proline as a green protectant in cryopreservation. The freezing temperatures of four kinds of cryoprotectants were compared with the one of proline by DSC tests, and four kinds of composite cryoprotectants based on proline also presented a contrast. Then, four groups of living ants have implemented the freezing experiments, the ants fed by the higher concentration of proline held the higher survival rate after freezing. Also, the results indicated that proline was provided with the stronger anti-icing effect and could significantly improve ants' freezing inhibition ability. This work would provide useful experience for cryopreservation solutions in vivo of microorganisms.
