摘要：
Newly isolated polysaccharide assimilating yeasts are added to a waste water rich in nutrients thereby making such yeasts assimilate nutrients, so that B.O.D. of the waste water is efficiently decreased. Among the polysaccharide assimilating yeasts, ellipsoideus YS-1, FERM-P No. 4498, in particular, can decompose and assimilate sulfurous acid, starch and protein at once, and therefore the B.O.D. of the waste water from starch production plants can be considerably decreased.
