Exciting new approaches use bacteria to capture carbon, mitigate fertilizer use, or other climate interventions. However, Bacteria are not well-adapted to these new-to-nature conditions, and many such technologies could be improved by domesticating bacteria to improve their performance and climate impact. BioBloom is a new method of barcoded directed evolution at the genome-scale, and this project pilots this method in a fertilizer-producing bacterium and a fast-growing photosynthetic bacterium.
