Sporotrichum schenckii

Cytochemical staining, by a method involving oxidation with periodate and reaction with thiosemicarbazide and osmium tetroxide, has revealed the presence of polysaccharide lamellae on the surface of the cell membrane of Claviceps purpurea.The membranous clusters in vacuolar bodies of the endoplasmic reticulum membranes, tonoplasts, and cytoplasmic membranes are covered with these lamellae. Somatic and metabolic polysaccharides composed of D-mannose and L-rhamnose have been isolated from Certocystic stenoceras and Sporotrichum schenckii , chemical and immunological analyses indicated close similarities in their structures. When pseudoplasmodia of Dictyostelium discoideum were incubated with 2-acetamido-2-deoxy-D-[ H]glucose, the label was incorporated into a polysaccharide in the slime sheath. The incorporated label disappeared...
