【 摘 要 】

Biomethanisation of an Euphorbiacea has been carried out in mesophilic condition (37°C) and in moderate thermophilic condition (48e'C) in batch digestors loaded at 5 % with dry matter. Three various preparation were studied. The fermentexibility of the plant is shown with productivites comparable to and even often higher than other biomasses. The best yield obtained in mesophilic condition with the ground plant 0.375 l/l/day) are only very slightly modified in moderate thermophilic condition (0.385 l/l/day). On the other hand with the coarse chopped plant, the yield is trebled with the temperature increase (0.238 l/l/day at 0.784 l/l/day).
