A Photographs of Chamber B (the BioCell) and Collection B1 and B5 (the two chambers that received liquid transfers during the flight test) post-flight for Experiment 1. Photographs of all chambers are provided in Figure S5, 6. B Growth of the engineered Pseudomonas putida KT2440 strain AW165 as measured by OD600. C Amount of βKA produced from TPA by cell cultivations. βKA abiotically decarboxylates to levulinic acid under high heat or low pH, so is quantified via levulinic acid, as described previously18.
