In order to obtain microorganisms which purify baker's yeast culture waste solution effectively without dilution, and to utilize the mycelium grown on the waste solution, a program was unertaken to assay the waste solution and study moulds of 86 genera, 152 species and 184 strains. The results found were as follows.1) Baker's yeast culture waste solution contains BOD 12,500 ppm, COD 19,000 ppm, pH 5.0〜5.5,total solids 4.5%, volatile solids 3.3% and ash 1.3%. The solids contain vitamins (inositol, pantothenic acid, niacin etc.) and metals (chiefly potassium and sodium). 2) Micro-organisms which grew especially well on the waste solution, belonged to Alternaria, Aspergillus, Curvularia, Neurospora, Ophiobolus, Sclerotium, Sterigmatocystis and Stysanus strains. The weights of these mycelia grown came to 6mg dry weight per ml. 3) The investigation of antimicrobial activity of 54 strains which grow well on the waste solution, were undertaken. It was found that 7 strains produce antibiotic substance in case of the culture on the waste solution. Especially Stysanus medius and Glomerella gossypii were active against Asp. niger.4) All of 10 strains which grow well on the waste solution removed about 60% of the BOD in the waste solution. Among the strains, there were no differences of BOD removal power.
