Using the hydrolysate, which had been produced by passing dilute sulfuric acid through a charge wood at high pressure, saccharification of raw sweet potato was performed. In such treatment, the hydrolytate obtained has about 15% reducing sugar. This hydrolysate after neutralization with lime is fermented by yeast, but the fermentation does not go no so smooth as the hydrolysate from raw sweet potato alone. Then we tried to ferment it smoothly by steaming, heating, addition of nutrients, alum or sulfurous salt etc. We recognized the good effect of steaming, but all other treatments proved ineffective ; even by steam treatment, the use of wood hydrolysate is rather worse than that of raw sweet potato only.
