Microemulsion-based organogels (MBGs) were effectively employed for the immobilization of four commonly used lipases. During the asymmetric hydrolysis of ketoprofen vinyl ester at 30 °C for 24 h, lipase from Rhizomucor miehei and Mucor javanicus immobilized in microemulsion-based organogels (RML MBGs and MJL MBGs) maintained good enantioselectivities (eep were 86.2% and 99.2%, respectively), an...

Enzymatic synthesis of sugar fatty acid esters were performed in an organic solvent using Immobilized Rhizomucor miehei (RMIM) lipase with sucrose and non-edible rice bran fatty acid as substrates. The maximum conversion of sucrose esters up to 78% obtained when sucrose and non-edible rice bran fatty acid were reacted in molar ratio of 1:8, using n-butanol as a solvent and 1% molecular sieves w...

A partial (634 bp) cDNA clone, AF1229, obtained from expressed sequence tags (ESTs) of solid-cultured basidiomes of Antrodia cinnamomea is homologous to the lipase gene in Rhizomucor miehei. 5'-rapid amplification of cDNA ends (RACE) and 3'-RACE amplification showed that the full-length lipase gene, Ac-LIP, has a 912bp open reading frame (ORF), a 183bp 5' non-coding region, and a 144bp 3' non-c...

The main monomer of tomato cuticle, 10,16-dihydroxyhexadecanoic acid (10,16-DHPA) and its methyl ester derivative (methyl-10,16-dihydroxyhexadecanote; methyl-10,16-DHHD), were used to study their oligomerization reactions catalyzed by five lipases: Candida antarctica lipase B (CAL-B), Rhizomucor miehei lipase (RM), Thermomyces lanuginosus lipase (TL), Pseudomonas cepacia lipase (PCL) and porcin...

Lipases are the most widely employed enzymes in commercial industries. The catalytic mechanism of most lipases involves a step called "interfacial activation". As interfacial activation can lead to a significant increase in catalytic activity, it is of profound importance in developing lipase immobilization methods. To obtain a potential biocatalyst for industrial biodiesel production, an effec...

Immobilization of enzymes is one of the most promising methods in enzyme performance enhancement, including stability, recovery, and reusability. However, investigation of suitable solid support in enzyme immobilization is still a scientific challenge. Polyethersulfone (PES) and aminated PES (PES–NH2) were successfully synthesized as novel materials for immobilization. Membranes with various po...
