Acidolysis between triolein and short-chain fatty acid by lipase in organic solvents.

Ten kinds of lipases were examined as biocatalysts for the incorporation of short-chain fatty acids (acetic, propionic, and butyric acids) into triolein in order to produce one kind of reduced-calorie structured lipids. Trans-esterification (acidolysis) was successfully done in n-hexane by several microbial lipases. Among them, lipase from Aspergillus oryzae was used to investigate the effects ...

A Newly Isolated Thermostable Lipase from Bacillus sp.

A thermophilic lipolytic bacterium identified as Bacillus sp. L2 via 16S rDNA was previously isolated from a hot spring in Perak, Malaysia. Bacillus sp. L2 was confirmed to be in Group 5 of bacterial classification, a phylogenically and phenotypically coherent group of thermophilic bacilli displaying very high similarity among their 16S rRNA sequences (98.5-99.2%). Polymerase chain reaction (PC...

Molecular cloning and characterization of a thermostable esterase/lipase produced by a novel Anoxybacillus flavithermus strain.

A thermophilic strain producing an extracellular esterase/lipase was isolated from a hot spring in Tăşnad, Romania, and was identified phenotypically and by 16S rDNA sequencing as Anoxybacillus flavithermus (GenBank ID: JQ267733). The gene encoding the putative carboxyl esterase (GenBank ID: JX494348) was cloned by direct PCR amplification from genomic DNA. The protein, consisting of 246 amino ...

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...

The role of Glu87 and Trp89 in the lid of Humicola lanuginosa lipase.

The importance of Glu87 and Trp89 in the lid of Humicola lanuginosa lipase for the hydrolytic activity at the water/lipid interface was investigated by site-directed mutagenesis. It was found that the effect on the hydrolytic activity upon the replacement of Trp89 with Phe, Leu, Gly or Glu was substrate dependent. The Trp89 mutants displayed an altered chain length specificity towards triglycer...
