SUMMARY The effect of 3‐O‐methyl glucose on the carbohydrate metabolism of, and loss of 14 C‐labelled compounds from, mycelium of Dendryphiella salina pretreated with [U‐ 14 C]mannitol was investigated. Though concentrations of mycelial glycerol were higher than previously reported, the results for other internal carbohydrates were generally similar. In particular, the sugar reduced the concentration of mannitol. Loss of radioactivity into the medium was increased by 3‐O‐methyl glucose. The pattern of loss cannot yet be explained but since there was no loss of labelled mannitol or arabitol, unspecific membrane damage seems unlikely.
