Upgrading of farmed salmon oil obtained from by-products was carried out by lipase-catalyzed hydrolysis to increase omega 3 polyunsaturated fatty acids (PUFA) content. The lipases tested were from Penicillium camembertii (PC), Rhizomucor javanicus (RJ), Rhizopus niveus (RN), Rhizopus delemar (RD), Burkholderia cepacia (BC), Rhizopus oryzae (RO), Candida rugosa (CR) and Rhizomucor miehei (RM). The lipases from PC, RJ and RN had lower hydrolysis degrees (HDs) compared to the rest of the lipases…

Enzymatic preparation of linoleic acid from sunflower oil: an experimental design approach
Enzymatic preparation of linoleic acid from sunflower oil was examined through a statistical approach. Initially, enzyme screening for oil hydrolysis was investigated. The results indicated that
Enhancement of activity and selectivity of Candida rugosa lipase and Candida antarctica lipase A by bioimprinting and/or immobilization for application in the selective ethanolysis of fish oil
TLDR
Fatty acid selectivity of CALA was significantly improved by immobilization combined with bioimprinting, resulting in 5.5-fold lower omega-3 PUFA in EE.
Investigation on oil extraction methods and its influence on omega-3 content from cultured salmon.
TLDR
The preliminary quality analysis of the oil extracted from different salmon parts at different temperatures and reaction times and the presence of higher EPA, DPA and DHA suggested that the oil had good quality standards; it is not oxidized and can be subjected to various nutraceutical applications.
Immobilization of Thermomyces lanuginosus lipase on multi-walled carbon nanotubes and its application in the hydrolysis of fish oil
In this study, lipase from Thermomyces lanuginosus (TLL) was immobilized on carbon nanotubes (MWCNTs) by physical adsorption, and the immobilizing conditions were optimized for maximum activity. The
Efficient Candida rugosa lipase immobilization on Maghnite clay and application for the production of (1R)-(−)-Menthyl acetate
This work focused on the identification of natural, economical, and efficient supports for immobilization of Candida rugosa lipase (CRL) to catalyze the resolution of (±)-menthol. To this purpose,
Candida rugosa Lipase Immobilized onto Acid-Functionalized Multi-walled Carbon Nanotubes for Sustainable Production of Methyl Oleate
TLDR
Physical adsorption of CRL onto acid-functionalized MWCNTs has improved the activity and stability of C RL and hence provides an environmentally friendly means for the production of methyl oleate.
Substrate structure and computation guided engineering of a lipase for omega-3 fatty acid selectivity
TLDR
Engineering the binding pocket of a complex substrate, such as a triglyceride, with the supportive information on substrate structure and its binding modes with the enzyme provided by computational methods has resulted in designing two efficient lipase variants with improved substrate selectivity.
A Study on Classification of Fish Oil Types and Its Usage by 13 C-NMR Spectra and Fatty Acids Analysis
This study estimates the classification criteria which distinguishes the types of omega-3 health functional foods, fish oils and fish oil usages through 13 C-NMR spectra and fatty acids contents

Lipase-assisted concentration of n-3 polyunsaturated fatty acids from viscera of farmed Atlantic salmon (Salmo salar L.)
TLDR
Salmon viscera were a good source for fish oil, and the concentration of Eicosapentaenoic acid and EPA was doubled by using microbial lipases.

TLDR

TLDR
By controlling the degree of hydrolysis, two products have been obtained, one enriched in total n-3(∼50%), the other enriched in DHA and depleted in EPA (DHA∼40%, EPA∼7%).
