Next we want to know if our conclusions made for glucose are also valid for the environment close to the banana roots. To approach this realistic as possible the carbon source is changed to have the same ratio of carbohydrates and amino acids as found in the exudates of banana roots [26]. This new carbon composition causes a reduced growth rate because of less efficient degradation of these compounds. In figure 5 the relative growth rate is shown for the resting and active state based on root exudate composition. The relative growth rate of BananaGuard around the roots has slightly decreased compared to glucose as carbon source but is still above 45%. This indicates it still has the capacity to grow and maintain the constant fungal growth inhibitor production with one condition that BananaGuard needs to stay close to the roots to maintain its carbon uptake rate. From this we can conclude that these changes in the carbon composition do not change our previously made conclusions .
