1. Size of inoculum has been studied : All fermentations were ended normally by using inoculum equivalent to 0.05〜0.4% of the mash as in the case of a larger amount in the fermentation of 10% mashes.2. Effect of successive transfers of the seed on the fermentation has been studied, and the best results were obtained when the 5th transfers were used as inoculum in the fermentation of 10% corn mashes.3. If fermented mash is used as a starting culture, it is better to use the mashes stored for 7〜75 days from the time of inoculation.4. The relation between the age of the seed culture and its fermentive power has been studied, using the seeds cultured for 11〜30 hr; all seeds gave the same normal results in fermentation period and solvent yield in the fermentation of 10% corn or kaoliang mashes.
