  • Title: [Effect of sulfur-containing compounds on the ultrastructural organization of the cell wall of Candida utilis yeasts].
    Author: Biriuzova VI, Lobyreva LB, Kostrikina NA.
    Journal: Mikrobiologiia; 1982; 51(6):950-3. PubMed ID: 6891430.
    Abstract:
    The effect of sulfur-containing compounds (cysteine, homocysteine, glutathione, cystine, and methionine) on the ultrastructural organization of the cell wall was studied in Candida utilis 295t by electron microscopy with the aid of staining SH groups by HgCl2. Treatment of the cells with cysteine and homocysteine was found to modify the ultrastructure of the cell wall: the capsule was damaged and the porosity increased, which facilitated the penetration of these compounds into the periplasm. Their further conversion in the cell has been studied.
