Abstract

In this study, the waste sulphite liquor (W.S.L.) of the Izmit-SEKA factory was tested for its utilization rate in single cell production. The optimum growth requirements of Candida tropicalis ceppo 571 yeast in sulphite liquor medium were examined. 34% and 28.6% reduction in C.O.D. (Chemical Oxygen Demand) and B.O.D. (Biochemical Oxygen Demand) were observed respectively at the end of the growth period. The 2-3% fermentable carbohydrate content of the liquor was converted bio-mass with a rate of 66.6%. The optimum growth yield was reached by the stripping of 25% of the total volume, 30 degrees C, pH: 6.0 conditions.
