Figure 5 depicts how the growth rate of BananaGuard compares to the growth rate of the wild type P. putida depending on the carbon uptake rate of the organism in the resting state and active state of the kill switch. Glucose was chosen as carbon source reference, because of the efficient degradation of glucose. BananaGuard is still able to grow at almost max growth rate (>99%) compared to the wild type in the resting state. We can conclude from this that BananaGuard is not outcompeted by other rhizosphere-populating microorganisms because of the synthetic pathway. When the kill switch is activated by fusaric acid, BananaGuard is still able to growth with 50-65% of the maximum growth of the wild type (Figure 5). This indicates that metabolic stress is not a bottleneck for the production of fungal growth inhibitors in our fusaric acid activated system.
