“…The use of lipase-catalyzed transesterification reactions in low-water media has been pursued recently as a promising approach to overcoming these problems [3,5]. It was expected that the application of lipases could afford high conversion yields of oils and simplify downstream product purification at the same time [6,7].…”

Lipase AK was modified with short alkyl chains to form a highly organic soluble enzyme and was used to catalyze the synthesis of biodiesel from soybean oil in organic media. The effects of several key factors including water content, temperature, and solvent were examined for the solubilized enzyme in comparison with several other commercially available lipases. Whereas native lipases showed no activity in the absence of water, the organic soluble lipase demonstrated reaction rates of up to 33 g-product/genzyme h. The biocatalyst remains soluble in the biodiesel product, and therefore, there is no need to be removed because it is expected to be burned along with the diesel in combustion engines. This provides a promising one-pot mix-and-use strategy for biodiesel production.

“…The ME content in the final-step elute reached 90-93 %, and the lipase could be used for at least 100 days in both reaction systems without any significant decrease in the conversion rate. The effect of pretreatment of Novozym 435 on methanolysis for biodiesel fuel production was investigated by Samukawa et al 35 Methanolysis progressed much faster when Novozym 435 was preincubated in methyl oleate for 0.5 h and subsequently in soybean oil for 12 h, with the ME content in the reaction mixture reaching over 97 % within 3. 22 lipases in a water-containing system with no organic solvent.…”

In this paper, the reaction of enzymatic trans-esterification of glycerides with ethanol in a reaction medium containing hexane at a temperature of 37 degrees C has been studied. The enzyme was Lipase from Mucor miehei, immobilized on ionic exchange resin, aimed at achieving high catalytic specific surface and recovering, regenerating and reusing the biocatalyst. A kinetic analysis has been carried out to identify the reaction path; the rate equation and kinetic parameters have been also calculated. The kinetic model has been validated by comparison between predicted and experimental results. Mass transport resistances estimation was undertaken in order to verify that the kinetics found was intrinsic. Model potentialities in terms of reactors design and optimization are also shown.
