Optimization of the Lipase Catalyzed Production of Structured Acylglycerols With Polyunsaturated Fatty Acids Isolated From Sardine Oil

Lipase-Catalyzed Transesterification of Egg-Yolk Phophatidylcholine with Concentrate of n-3 Polyunsaturated Fatty Acids from Cod Liver Oil.

Phospholipids containing PUFAs are important vehicles for their delivering to the targeted tissues. In our research project we established enzymatic methods for the enrichment of natural egg-yolk PC with n-3 PUFAs. Instead of synthetic PUFA ethyl esters, the new strategy was developed using polyunsaturated fatty acids enriched fraction (PUFA-EF) from cod liver oil as the natural acyl donors. PU...

structured lipids produced through lipase-catalyzed acidolysis of canola oil

enzymatic acidolysis of canola oil through caprylic acid was investigated to produce certain medium chain ttriacyliglycerol (tag) structured lipids (sls). lipozyme tl im, an sn-1,3 specific thermomyces lanuginosa lipase, and novozym 435, a non-specific candida antarctica lipase, were utilized as the biocatalysts in a batch reactor. reaction conditions were designed according to taguchi’s approa...

Production of MLM-Type structured lipids from fish oil catalyzed by Thermomyces lanuginosus lipase

Background Lipases are powerful tools for the syntheses of structured lipids (SL) which are triacylglycerols (TAG) having particular fatty acid residues at specific positions. The production of TAG with medium chain fatty acids (MCFA), in positions sn-1 and sn-3, and a long-chain fatty acid (LCFA), in the internal position, has recently increased due to its nutritional interest in applications ...

Production of polyunsaturated fatty acids by microorganisms.

Synthesis of structured triacylglycerols enriched in n-3 fatty acids by immobilized microbial lipase

The search for new biocatalysts has aroused great interest due to the variety of micro-organisms and their role as enzyme producers. Native lipases from Aspergillus niger and Rhizopus javanicus were used to enrich the n-3 long-chain polyunsaturated fatty acids content in the triacylglycerols of soybean oil by acidolysis with free fatty acids from sardine oil in solvent-free media. For the immob...
