PROBLEM TO BE SOLVED: To obtain a new variant which is a yeast variant Trichosporon sp.M 111-HAG-No.3 having high-aggregation activity, and capable of efficiently aggregation-treating a distilled waste solution of wines in a short time by combinedly using vegetable fibers with this variant. SOLUTION: This high-aggregation active variant is a new yeast variant Trichosporon sp.M111-HAG-No.3 (FERM P-14997). Solid materials in a distilled waste solution of wines composed of a distilled waste solution of low-class distilled spirits using wheat, rice or buckwheat, etc., and/or a distilled waste solution of an alcohol, etc., can efficiently be aggregation-treated in a very short time by combinedly using vegetable fibers and/or materials containing them with this variant. This new variant is obtained by using a fiber-aggregation yeast M111 strain as a mother stock, subjecting the stock to mutation treatment, testing an aggregation activity with cellulosic fibers and aggregation property and solid-liquid separating effect, etc., among the variants and selecting stocks having high activities of such properties. |
