| Outline of Final Research Achievements |
The aqueous two phase system (ATPS) has been well known as one extraction technique for biomolecules. In this study, water-miscible alcohol/salt and ionic liquid/salt ATPSs for the extraction of bioproducts such as organic acids amino acids, diols and so on were examined. Succninc acid was quantitatively extracted by ATPS compsed of water-miscible alcohol/salt.
The water-miscible alcohol/sugar and ionic liquid/sugar ATPSs were also exmained for the extarction of succinic acid. Succinic acid was successfully extracted with ATPS using sugar to extract using alcoholand ionic liquid. The pH condition of ATPS technique was really important in order to get high extractability．
