Shochu distillery waste contains high suspended solid (SS) material, so that high biochemical oxygen demand (BOD) concentration indicates above 40,000ppm. Shochu distillery waste is easy to be spoiled at ambient temperature within a few days. A study for the feasibility of utilizing shochu distillery waste as a substratc for acetone, butanol and ethanol fermentation by Clostridium saccharoperbutylacetonicum N1-4 (ATCC13564) was carried out. Shochu distillery waste used a s the solevants substrate, could not produce solvents because it does not contain sufficient level of substrate for fermentable. Elementary analysis of total sugar and amino acids of shochu distillcry waste from the process using sweet potato, buckwheat, wheat and sesame indicated those four types of shochu waste contained, 1.6～4.8(w/w% ) of tolal sugar, and 0.28～1.59(w/w %) of total nitrogen. Cooked rice hydrolyzed with enzyme was then supplemented to the waste. Waste made from sweet potato and that from buckwheat produced solvent while wheat waste and sesame waste did not. When discarded food whose composition was similar to garbage was supplemented, solvent production was improved marltedly.
