“…Ionic liquids also can affect enzyme activity through direct interaction with the enzyme and by altering the microenvironment of enzyme. Due to the conductivity and hydrophobicity, ILs are widely applied for electrode modification to obtain high heterogeneous electron transfer rates [34]. Therefore, ILs tolerant DA11 is promising for its application in biosensor.…”

To design D-amino acid dehydrogenase (DAADH) for enhanced stability, the interactions of the subunit interfaces of DAADH were analyzed. Interaction network analysis of DAADH indicated that there are only weak interactions between the A and B subunits. Several co-evolved residue pairs were selected for mutation to enhance interfacial interactions of subunits, and 11 designed MDHs were obtained. DA06 and DA11 were selected for experimental verification for their salt bridges are 1.4 and 1.2-fold of that of DAwild, respectively. DA11 can maintain 93% activity in 80℃, while it was only 40% for DAwild. Thermostabiliy study indicated the half-life of DA11 was 2-fold of DAwild. Molecular dynamics simulations revealed that the extraordinary stability of the DA11 was due to the formation of extra interfacial salt bridges. The paper provided a strategy of mutations outside the active site of enzyme by co-evolutionary analysis which can reduce the effect of the activity-thermostability trade-off.

“…25 Ionic liquids (ILs), as green solvents composed of anions and anions, are used in the enzymatic synthesis of chiral alcohols, chiral amines, and sugars and their derivatives, which greatly improve the catalytic effect. 26,27 Applying ILs to an immobilized enzyme can also improve the catalytic performance of the enzyme. For instance, we previously used imidazole IL as a crosslinking molecule to prepare a chitosan/SBA-15 composite for the immobilization of porcine pancreatic lipase (SBA-CIL-CS-PPL).…”

“…[8,16,[23][24][25] Room temperature Ionic liquids, ILs, present a series of unique properties such as low volatility, low toxicity, high solubility for metals combined with tunable hydrophobicity. [26][27][28][29] All these aspects make them appealing for many applications such as catalysts, [30] environmental contaminants removal systems, [31,32] electrolytes for energy storage devices, [33][34][35][36] and extracting agents. [37][38][39][40][41] Although recently many strategies have been reported to implement metals recovery and separation, such as membrane separation, ion imprinted polymers, solid phase adsorption, [42][43][44] liquid-liquid extraction is still appealing due to its robustness, ease of implementation, and scalability, making it exploited also at industrial scale.…”

Sustainable management of spent lithium-ion batteries, LIBs, is an urgent and critical challenge due to the number of such devices reaching the end-of-life. Recycling can offer a path for the recovery of valuable raw materials such as lithium and cobalt, whose supply is critical. Thus, it is mandatory to develop efficient ways for the selective recovery of Li and Co from the cathode degradation processes. In this study the most updated organic acids-based processes for the degradation of LiCoO 2 , the most common LIBs cathode, is explored to obtain a leached solution containing Li and Co. The possibility to exploit the 3-methyl-1-octylimidazolium thenoyltrifluoroacetone, Omim-TTA, ionic liquid was demonstrated to efficiently separate Li and Co. In particular it was possible to recover > 70 % of Li and separate it from Co using this ionic liquid, independently from the organic acid used for the leaching procedure and adding EDTA to the aqueous phase. The quantification was carried out through ICP analysis; the recovering of the unaltered ionic liquid was also demonstrated, to further increase the global sustainability of the process.
