Key Words Microbiological Studied on the Treatment of Waste Liquer from Pulp and Paper Industries (II)
Abstract Four strains of yeasts were chosen from those isolated previously, and a strain from 160 isolates collected in this year were examined for the treatment of pulp waste liquor. Experiments about optimum nutrient condition, composition of cells, and reduction of B.O.D. on the "S" pulp industry waste liquor were performed with 5 strains. 1. The isolates (strain 112) was identified as Candida utilis. 2. The optium concentration of 4 components of nutrients were (NH₄)₂SO₄lg/l, yeast extract 70mg/l, KH₂PO₄300mg/l, and MgSO₄·7H₂O 500 mg/l. 3. Specific growth ratio of Candida utilis KYRI 112 was 0.48/hr at optimum nutrient media and the yield was 0.45%(V/V). 4. Endomycopsis capsularis KYRI 613 contained more crude protein than the most of commercial yeasts. 5. The B.O.D. of waste liquor was reduced to 20% of its value by the culture.
