The fodder yeast (Mycotorula japonica) production from sulphite waste liquor was investigated at the Inuyama Pulp Mill of. Toyo Spinning Co. with the results as follows; When ammonium results were obtained in general; in the case of no addition of phosphate the yield of the product was very low. Ammonium sulphate and calcium superphosphate should not be used together owing to the formation of gypsum precipitate. The most suitable nutrients were aq. ammonia and calcium superphosphate, especially when accompanied by the simultaneous use of KCl at 2% for sugar. When sulphite waste liquor containing 4.5% sugar was fed at the rate of 3.5l per hour for the total liquid volume of 18l, the yield of dry yeast was 39% and 61%, respectively, for the total and consumed sugar. Air was conducted at the ras:e of 1 or 1/2 volume for the fermenued liquor without showing any difference in the results.
