A thermotolerant and flocculent yeast strain J-673 was isolated from the digestion tank of a yeast-activated sludge system for a soybean-cooking drain. The yeast was identified as Kluyveromyces marxianus var. marxianus. The yeast could be used for treatment of soybean-cooking drain water and water discharged from pot-stills of various shochu factories at temperatures over 40℃. In addition, the application of its flocculent and adherent chafracteristics to a continuous yeast treatment system for wastewater from a starch-producting factory was also investigated. The use of this yeast enabled saving to be made in the cooling water used for regulatoing the yeast tank temperature. The flocculation mechanism of the yeast was similar to that of Saccharomyces cerevisiae.
