Biodiesel Production from Dairy Waste Scum by Using a Efficient Nano-biocatalyst

Chemical Engineering Transactions, 2020
In the present paper, magnetic nanoparticles (Fe3O4 NPs) covered with tartaric acid (TA) have been synthesized through an "eco-friendly approach" and subsequently used for direct physical immobilization of the lipase from Thermomyces lanuginous (TLL ...

Activated Carbon as Support for Lipase Immobilization

Eurasian Chemico-Technological Journal, 2003
Lipase from Candida rugosa was immobilized onto four different types of activated carbon; KI/2030, KI/3040, KI/5060 and KI/6070. The immobilized lipase was used in the esterification of oleic acid and 1- butanol in hexane. The effects of difference pore

OPTIMIZATION OF LIPASE IMMOBILIZATION [PDF]

International Journal of Engineering, 2012
Pseudomonas aeruginosa BBRC-10036 was used for lipase production. The organism secreted the enzyme extracellulary. In order to purify the enzyme, precipitation was done first, and then this lipase has been purified by Ion exchange Chromatography leading to 2.3-fold purification and 11.47% recovery.

Enzymatic Interesterification of Crude Palm Oil with Methyl acetate: Effect of Pre-treatment, Enzyme’s Dosage and Stability

Bulletin of Chemical Reaction Engineering & Catalysis, 2023
In the present study, biodiesel was produced via the enzymatic interesterification of Crude Palm Oil (CPO) and methyl acetate within ultrasonic condition. In contrast to alcohol, methyl acetate as an acyl acceptor does not inhibit lipase activity and can

Immobilization of Lipase from Thermomyces Lanuginosus and Its Glycerolysis Ability in Diacylglycerol Preparation

Molecules
In the glycerolysis process for diacylglycerol (DAG) preparation, free lipases suffer from poor stability and the inability to be reused. To address this, a cost-effective immobilized lipase preparation was developed by cross-linking macroporous resin ...

Comparative performance of microbial lipases immobilized on magnetic polysiloxane polyvinyl alcohol particles

Brazilian Archives of Biology and Technology, 2008
Microbial lipase from Mucor miehei and Candida rugosa were immobilized by covalent binding onto magnetized polysiloxane polyvinyl alcohol particles (POS-PVA). The resulting immobilized derivatives were evaluated in aqueous solution (olive oil hydrolysis)
