Fungal enzymic activity degrading 1,4-α- d-glucans to echinosporin (5-epipentenomycin I)

When subjected to ‘activating’ plasmolytic treatments, the Discomycete Peziza echinospora exhibits an enzymic activity which degrades 1,4-α- d-glucans to 1,5- d-anhydrofructose, and then converts this sugar to echinosporin (5-epipentenomycin I), that had not been previously reported as a pure enanti...

Zusammenfassung:	When subjected to ‘activating’ plasmolytic treatments, the Discomycete Peziza echinospora exhibits an enzymic activity which degrades 1,4-α- d-glucans to 1,5- d-anhydrofructose, and then converts this sugar to echinosporin (5-epipentenomycin I), that had not been previously reported as a pure enantiomer. Biogenetical, mycological and practical consequences of this bioconversion are discussed.
