Protective excipients, known as lyoprotectants, safeguard cells during lyophilization to mitigate viability loss, with current research mostly focuses on a few sugar or sugar-derivatives, like trehalose and sucrose. To expand the repertoire of lyoprotectants and customize the formulation for specific strains of interest, herein, we report “growth monitoring” as a novel method for the high-throughput screening of lyoprotectants for bio-engineered Saccharomyces Boulardii, a probiotic yeast strain that promotes gastrointestinal health. Thereafter, leveraging this innovative and efficient screening approach, we expanded the repertoire of lyoprotectants beyond the commonly studied excipients and identified promising candidates. Also, by utilizing the extensive screening data for multivariate analyses, this research offers new insights into the molecular characteristics of effective lyoprotectants, facilitating the discovery of next-generation lyoprotectants.
