Spontaneous L-transformation was described in Actinomadura and Nocardiopsis. Cultures growing for two days were found to contain polymorphous cells (0.5 to 1.5 mum) lacking a cell wall. A considerable portion of the cell is occupied with a nucleoid while the cytoplasm is forced toward the periphery of the cell. Membranous structures formed by five-layer membranes can be seen in the cytoplasm. Budding has been observed. The above features are typical of bacterial L-forms and has not been found in cells with an intact cell wall.
在马杜拉放线菌和拟诺卡氏菌中发现了自发L型转化。发现培养两天的培养物中含有缺乏细胞壁的多形细胞（0.5至1.5微米）。细胞的相当一部分被类核占据，而细胞质被挤向细胞周边。在细胞质中可以看到由五层膜形成的膜状结构。已观察到出芽现象。上述特征是细菌L型的典型特征，在具有完整细胞壁的细胞中未发现。
