“…It is also noticeable that the consortium is constituted by a halophilic bacterium previously isolated in southern Spain saltworks (Halomonas sp. LM1C), 16 thus confirming our previous conclusions that the naturally developed resistance to salts or hydrocarbons is advantageous to ease ionic liquids metabolization. More specifically, a previous research work 24 demonstrated greater biodegradation levels for choline chloride (about 20%) in samples containing microbial strains coming from saline soils.…”

This work is a first approach to demonstrate the viability of a quantitative biotechnological removal of choline chloride from aqueous effluents. Despite the much vaunted biocompatibility of this ammonium-based ionic liquid, it was demonstrated (both by an ad-hoc F test recommended by the Organization for Economic Co-operation and Development and flask assays) that different microorganisms able to degrade persistent chemicals were not able to metabolize it. Only a halophilic bacterium, recently isolated in our research group (Halomonas sp.), exhibits the enzymatic mechanism to catalyze the cleavage of the ionic liquid cation. The biotechnological process was optimized by carefully cherry-picking the carbon source and proposing an adaptation strategy. In this way, a complete choline removal was attained in less than 24 h when the surfactant Tween 80 was added to the ionic liquid-containing aqueous effluent.

“…In the present study, the tetracomponent system conformed by {Potassium phosphate (K 3 PO 4 )+Choline Glycinate (ChGly)+Triton X‐102+H 2 O} at 30 °C was analysed. As reported before, {K 3 PO 4 +Triton X‐102+H 2 O}, {ChGly+Triton X‐102+H 2 O} and {K 3 PO 4 +ChGly+H 2 O} are able to engender ABS and, therefore, according to Mace et al . the four components should be able to generate an A3PS.…”

Setting the Foundations of Aqueous Three‐Phase Systems (A3PS) in the Quest for a Rational Design

This work presents the first in‐depth study of Aqueous Three‐Phase Systems (A3PS) with the main purpose of unveiling their behaviour, hence contributing to the development of this new field. Thus, a complete definition of a quaternary system was carried through by describing all the regions in detail to represent them later on in a regular‐tetrahedral diagram. The three aqueous faces of the tetrahedron demonstrated an undeviating influence in the segregation capacity. Furthermore, a method for comparing Aqueous Biphasis Systems (ABS) immiscibilities was set up in order to allow the evaluation and detection of the “limiting ABS” for the three‐phase region. Finally, all this information was compiled and utilised to obtain a new strategy for an A3PS rational design, which can be applied with ABS libraries or in an experimental approach. In this sense, this strategy represents an undoubted advance towards future studies and development of A3PS, as this sequential application of the constructed knowledge is assumed to save time and resources.

“…These systems are formed when phase separation spontaneously occurs between two water-soluble compounds at a certain composition. ABS have shown to be effective in numerous applications like biomolecules extraction [19,20], environmental remediation [21,22], or purification processes [23] and have been boosted in recent years with the emergence of neoteric solvents like ionic liquids or DES.…”
