S ummary When mycelium of Dendryphiella salina Nicot & Pugh is exposed for 5 h to media containing various concentrations of the very slowly metabolized sugar, L‐sorbose, the total ethanol‐soluble carbohydrate content increases and there is also a stimulated synthesis of mannitol. Provided L‐sorbose is absorbed, the presence of glucose, fructose, mannitol or arabitol in the medium does not prevent these changes which are different from those brought about by the non‐metabolizable sugar, 3‐ O ‐methyl glucose. It is suggested that the apparent regulation of mycelial ethanol‐soluble carbohydrate concentration following uptake of the latter sugar cannot be controlled primarily by turgor.
