“…However, the use of solvents brings additional costs and environmental concerns (46,51,52). To overcome these drawbacks, the adoption of solvent-free systems for enzymatic esterification has increased interest in the last decades (6,45,(53)(54)(55)(56)(57)(58)(59)(60)(61)(62)(63). Many studies have obtained, with different degrees of yields, esters by enzymatic route in solvent-free systems for applications in cosmetics, personal care products, and biofuels, as reviewed by Khan & Rathod (2015 (5,64), Pourzolfaghar et al (2016) (65), Sá and coworkers (2017) (8), and Antczak and co-workers (2009) (48).…”

“…Lipases (triacylglycerol acyl-hydrolase, EC 3.1.1.3) are biocatalysts naturally robust and efficient, can be used for the production of many different molecules, and have a wide range of industrial applications thanks to their broad specificity and commercial accessibility [1][2][3]. Among these molecules of interest is ethyl oleate, which is an ester with applications in cosmetics, in the food industry but also in the production of biofuels as biodiesel [4][5][6].…”

Lipases are an important group of biocatalysts for many industrial applications. Two new commercial low-cost lipases Eversa® Transform and Eversa® Transform 2.0 was immobilized on four different hydrophobic supports: Lewatit-DVB, Purolite-DVB, Sepabeads-C18, and Purolite-C18. The performance of immobilized lipases was investigated in the transesterification of sunflower oil solvent-free in an anhydrous medium. Interesting results were obtained for both lipases and the four supports, but with Sepabeads support the lipases Eversa showed high catalytic activity. However, the more stable and efficient derivative was Eversa® Transform immobilized on Sepabeads C-18. A 98 wt% of ethyl ester of fatty acid (FAEE) was obtained, in 3 h at 40ºC, ethanol/sunflower oil molar ratio of 3:1 and a 10 wt% of the immobilized biocatalyst. After 6 reaction cycles, the immobilized biocatalyst preserved 70 wt% of activity. Both lipases immobilized in Sepabeads C-18 were highly active and stable in the presence of ethanol. The immobilization of Eversa Transform and Eversa Transform 2.0 in hydrophobic supports described in this study appears to be a promising alternative to the immobilization and application of these news lipases still unexplored.

Among these molecules of interest is ethyl oleate, which is an ester with applications in cosmetics, in the food industry but also in the production of biofuels as biodiesel [4][5][6] In December 2014, a new soluble lipase called Eversa® Transform was launched by Novozymes S / A (Denmark) with potential for use in industrial enzymatic biodiesel production processes [7]. After, in May 2016, the company announced the second generation of lipase, Eversa Transform 2.0, with greater thermostability [7].…”
