^aRhamnolipids (Rhls), pyocyanin (Pyo) and elastase (Elast) production was determined after 24 hours of growth at 30°C and 37°C. ND* means not detected. Swimming (Swim) and swarming (Swar) phenotypes were determined as described in Materials and Method section. Examples of motility phenotypes are shown in the supplementary materials.
