The yellowish and hydrophobic PEFA droplets secreted by the strain P4R5 in the culture (A). Intracellular lipid particles (yellow ones) and extracellular liamocin particles (red ones) produced by the strain P4R5 was observed under a phase-contrast microscope (B) and a fluorescence microscope (C). The strain R4P5 was aerobically grown in the PEFA screening medium at 28 °C for 144 h, and the harvested culture broth was stained with Nile Red
