Microorganisms have been used for millennia to produce food and medicine and are now being developed as products themselves to treat disease and boost crop production. However, as required for these new applications, maintaining high viability throughout manufacturing, transportation and use remains a significant challenge requiring sophisticated cold-chains and packaging. In fact, we found that commercial microbial products (probiotics) provide a poor solution to this challenge, in particular for key industrial organisms like E. coli. To overcome this technological gap, we report the development of synthetic extremophiles of industrially important gram-negative bacteria (E. coli Nissle 1917, Ensifer meliloti), gram positive bacteria (Lactobacillus plantarum) and yeast (Saccharomyces boulardii). Specifically, we developed a high throughput pipeline to define species-specific materials that allow these organisms to survive drying, elevated temperatures, organic solvents and even ionizing radiation. We enhanced the stability of E.coli Nissle 1917 by >4 orders of magnitude over commercial formulations and demonstrate the capacity to remain viable while undergoing tableting and pharmaceutical methodologies involving organic solvents. The development of synthetic materials-based enhanced stabilization stands to transform our capacity to apply microorganisms in extreme environments including those found on Earth as well as in space.
