“…Our previous results demonstrated that the catalytic efficiency of Pseudomonas fluorescens lipase in the acylation reaction of secondary alcohols could be enhanced by the presence of hydrophobic alkyl groups in the hybrid organic-inorganic sol-gel matrix, and utilization of ILs as nonstructural template compounds (Péter et al, 2008;Zarcula et al, 2010). Recently, ternary silane mixtures, containing alkyl-triethoxysilanes, phenyl-triethoxysilane and tetraethoxysilane, have been reported with higher catalytic efficiency than the corresponding binary silane mixtures, for the sol-gel entrapment of Celite-supported Pseudomonas fluorescens lipase (Tomin et al, 2010).…”

Candida rugosa lipase (CRL) was immobilized on an eco-friendly support poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV), by physical adsorption, using different ionic liquids (ILs) as immobilization additives. This was to investigate the influence of cationic core ([C4mpy]Cl, [C4min]Cl), of anions ([C4min]Cl, [C4min]N(CN)2, [C4min]Tf2N), and of cation chain length ([C2min]Tf2N, [C4min]Tf2N) in the immobilization process. The immobilized biocatalysts (IB) were characterized with respect to the morphological, physico-chemical properties, total activity recovery yield (Ya), and biochemical properties of more efficient IB were evaluated. Initially, it was found that the change of cationic core did not influence in Ya compared to the control. With change of anions, it was seen that the best result was obtained for the more hydrophobic anion (Tf2N), and finally increasing the cation chain length increased Ya. IB most efficient with [C4min]Tf2N obtained 78 % of Ya, more than twice the control value (30 %) and a considerable enhancement of operational stability compared with the control.
