Soluble sugars in the mycelium of the basidiomycete Oudemansiella mucida.

Quantitative gas chromatography was used to determine soluble neutral sugars in an extract of the fungus Oudemansiella mucida grown on a synthetic glucose medium. Apart from the usual fungal sugar components, viz. trehalose, D-glucose, D-mannitol, D-arabinitol, glycerol and inositol, the 6-day-old mycelium contained D-arabino-2-hexosulose (D-glucosone). In the period of maximum growth, this aldoketose was the predominant monosaccharide (3.4% mycelial dry weight).
