By ultrastructural methods, cytology, and cytochemistry it is shown that peroxysomes are present during all stages of the life cycle of the green unicellular alga Micrasterias fimbriata, cultivated on mineral medium. These organelles, surrounded by a single membrane, are in connection with endoplasmic reticulum. In full-grown cells, they are preferentially situated near chloroplasts and cell walls. The number of peroxisomes increase before cellular division and the organelles flow into the young bulge in front of the chloroplast.Application of a modified Graham and Karnosky's medium using DAB at pH 9 shows that an important activity of catalase is present not only at the level of peroxisomes but also at the level of the cell walls and certain Golgi vesicles.The topographic relations of peroxisomes with different cellular organelles and their possible functions in cell wall or mucus synthesis are discussed.
通过超微结构方法、细胞学和细胞化学研究表明，在以矿物培养基培养的绿色单细胞藻类纤毛微星鼓藻生命周期的所有阶段都存在过氧化物酶体。这些由单层膜包围的细胞器与内质网相连。在成熟细胞中，它们优先位于叶绿体和细胞壁附近。过氧化物酶体的数量在细胞分裂前增加，并且这些细胞器流入叶绿体前方的幼嫩凸起中。使用pH值为9的二氨基联苯胺（DAB）的改良格雷厄姆和卡尔诺斯基培养基显示，过氧化氢酶的重要活性不仅存在于过氧化物酶体水平，也存在于细胞壁和某些高尔基体囊泡水平。本文讨论了过氧化物酶体与不同细胞器的拓扑关系及其在细胞壁或黏液合成中的可能功能。
