Efficient Fractionation of Lipids in a Multiproduct Microalgal Biorefinery by Polymers and Ionic Liquid-Based Aqueous Two-Phase Systems
نویسندگان
چکیده
For a multiproduct microalgal biorefinery, most of the cell components should be extracted and fractionated. This work investigates fractionation lipids from other (pigments, proteins, carbohydrates) using polymers IL solutions in aqueous two-phase systems (ATPS). The poorly migrated to phases ATPS were recovered (97% total fatty acids) third phase (interphase) formed between top bottom phases. Studies with canola oil purified phospholipids suggest that high amount oil, phospholipids, natural emulsifiers present microalgae mixed water form an emulsion which is difficult fractionate. However, solution polypropylene glycol 400 (25% w/w) displaced 73% immiscible layer was easy recover. When combining this approach subsequent ATPS, biomolecules (lipids, pigments, could fractionated three-step mild separation concept.

Critical assessment of the formation of ionic-liquid-based aqueous two-phase systems in acidic media.
In this work, the ability of Na(2)SO(4) and ionic liquids to induce the formation of acidic aqueous two-phase systems (ATPS) is investigated. Ternary phase diagrams, tie lines, and tie-line lengths for several systems were determined and reported at 298 K and atmospheric pressure. It is here shown that among the ionic liquids studied only those containing long alkyl side chains at the ions and/...
متن کاملThermoreversible (Ionic-Liquid-Based) Aqueous Biphasic Systems.
The ability to induce reversible phase transitions between homogeneous solutions and biphasic liquid-liquid systems, at pre-defined and suitable operating temperatures, is of crucial relevance in the design of separation processes. Ionic-liquid-based aqueous biphasic systems (IL-based ABS) have demonstrated superior performance as alternative extraction platforms, and their thermoreversible beh...
متن کاملAqueous polymer two-phase systems formed by new thermoseparating polymers.
A set of new polymers that can be used as phase forming components in aqueous two-phase systems is presented. All polymers studied have thermoseparating properties i.e. form one separate polymer enriched phase and one aqueous solution when heated above the critical temperature. This property makes the polymers attractive alternatives to the polymers used in traditional aqueous two-phase systems...
