CELL-WALL ANCHORING TO CYTOPLASMIC MEMBRANE OF CANDIDA-ALBICANS

Cell wall ultrastructure of the opportunistic pathogenic yeast Candida albicans was investigated by stereoscopic freeze-etching technique. Three wall layers were distinguishable by this technique. No clear periplasmic space was evident. Bilayer membrane invaginations were extensive. The outermost regions of the membrane invaginations were lined with thin, spine-like fibrils, which extended into the cell wall. We suggest that the fibrils along the invaginations are involved in anchoring the cell wall to the membrane.
