Exponentially growing cells of the gram-negative bacterium Chromobacterium violaceum demonstrate invaginations of the cytoplasmic membrane with a high frequency. These invaginations conform to the ultrastructural appearance of mesosomes of gram-positive bacteria. As many as four mesosomes are observed per cell, each of which may increase the total membrane surface of the cell by 30%. Washing of cells in dilute tris(hydroxymethyl)aminomethane buffer effects a distension of the mesosome "neck" and/or cytoplasmic membrane clarifying the association of the mesosome to the cytoplasmic membrane. Plasmolysis effects an eversion of the mesosome into the plasmolysis vacuole.
革兰氏阴性菌紫色杆菌指数生长期的细胞频繁出现细胞膜内陷。这些内陷与革兰氏阳性菌中质体的超微结构外观一致。每个细胞中可观察到多达四个质体，每个质体可使细胞的总膜表面积增加30%。在稀的三（羟甲基）氨基甲烷缓冲液中洗涤细胞会导致质体“颈部”和/或细胞膜扩张，从而阐明质体与细胞膜的关联。质壁分离会使质体翻转到质壁分离液泡中。
