Ionic liquid-based multi-stage sugaring-out extraction of lactic acid from simulated broth and actual lignocellulosic fermentation broth
| • | IL-based sugaring-out extraction was applied to separate LA from fermentation broth |
| • | Different ILs and saccharides consisting systems were examined |
| • | The ability to form ATPS is in the order of [Hmim]BF4 ≈ [Bmim]BF4˃[Emim]BF4 |
| • | The partition behaviors of LA, [Bmim]BF4, and saccharides were evaluated |
| • | LA recovery of 89.8% was obtained with removal of 68.4% cells and 65.4% pigments |
