Abstract

    Various engineered bacteria showed useful functions. However, the storage of these bacteria usually requires -80℃ refrigerators, which substantially limited their transportation and usages in daily life. Therefore, we decided to utilize TDPs from tardigrades (water bears) to supply a new storage method. By introducing the TDPs as the protectants into bacteria during lyophilization (freeze-drying), we could produce dry live-bacteria powder. The powder then can be stored at room temperature for a long time, without any usage of professional equipment. This year, we confirmed that certain TDPs have the ability to maintain the survival rate of E. coli. We also optimized the method by regulating the expression level and combining different TDPs. In addition, we proved the modularity and tried to regulate the degradation of TDPs after freeze-drying. Considering that many iGEM teams and reseachers are designing engineered bacteria for various application scenarios out of laboratory, we hope the improved biopreservation method would promote their practical application.
