Abstract: | Electron-microscopic examination of the ultrastructure of Torulopsis candida cells grown on glucose and hexadecane revealed a well-developed network of canals in the cell wall of yeasts grown on hexadecane. These canals appeared in the non-adapted cells at the initial hours of the cultivation and completed their formation at the end of the logarithmic phase. The investigation by the freeze-etching showed the exocytosis of "secretory granules" to take place at the periplasma of the cells, and the morphological relationship of the granules to the canals in the cell wall. |
