Yeast treatment of waste water discharged from a sake factory was examined.
A flocculent yeast showing high ability of TOC removal in the waste water from sake brewing was isolated from a settling tank in a sake factory. The yeast was designated as Hansenula anomala J 224. Although the flocculent ability of the yeast decreased with increasing of the glucose content in the medium, it was independent of its age of growth, pH of medium and incubation temperature.
H. anomala J 224 had higher ability for treatment of rice-washing water than non-flocculent H. anomala J 45-1 used in the practical waste water treatment. It was caltulated from the sedimentation test that the recovery of the yeast cells after waste water treatment willbe about 80% in the flocculent strain, in contrast to 20% in the non-flocculent strain.
