[Construction of mono/di-rhamnolipid ratios-manipulable strains and characterization of their corresponding surfactants' activity].

Rhamnolipids (RLs) have emerged as one of the most promising classes of biosurfactants. The ratio of mono-RL to di-RL plays a significant role in determining its performance. Therefore, strains whose production of mono-RL and di-RL are manuplable, have advantage on applications in various scenarios. In this study, we developed a
