• Summary Gram‐negative bacteria secrete small particles called membrane vesicles (MVs) into the extracellular milieu. While MVs have important roles in delivering toxins from pathogenic bacteria to eukaryotic cells, these vesicles also play ecological roles necessary for survival in various environmental conditions. Pseudomonas aeruginosa, which lives in soil, ocean, plant, animal and human environments, has become a model organism for studying these small extracellular particles. Such studies have increased our understanding of the function and biogenesis of bacterial MVs. Pseudomonas aeruginosa MVs possess versatile components and chemical substances with unique structures. These characteristics allow MVs to play their multifunctional biological roles, including microbial interaction, maintenance of biofilm structure and host infection. This review summarizes the comprehensive biochemical and physiochemical properties of MVs derived from P. aeruginosa. These studies will help us understand their biological roles of MVs not only in pathogenicity but also in microbial ecology. Also, the mechanisms of MV production, as currently understood, are discussed.
