Effect of Additional Amino Group to Improve the Performance of Immobilized Lipase From Aspergillus niger by Adsorption-Crosslinking Method

Frontiers in Energy Research, 2021
Adsorption-crosslinking is one of the immobilization methods to improve the reusability of lipase. It requires amino groups to reduce cross-link immobilization risk so that lipase–support interaction increases and the immobilization is attainable.

Body mass index and hepatic lipase gene (LIPC) polymorphism jointly influence postheparin plasma hepatic lipase activity

Journal of Lipid Research, 1998
The -514 polymorphism in the hepatic lipase gene (LIPC) is associated with decreased hepatic lipase activity. In the present study, the interaction between body mass index (BMI), the -514 polymorphism, and hepatic lipase activity was examined in 118 ...

Lipase activity in the human aorta

Journal of Lipid Research, 1970
The hydrolysis of triglycerides by grossly normal male human aortas has been studied in vitro. The tissue contains an acid lipase (pH optimum, 5.4) and an alkaline lipase (pH optimum, 8.8). Both lipases catalyze the hydrolysis of saturated triglycerides;

CHARACTERIZATION OF IMMOBILIZED LIPASE IN ALUMINOSILICATE FOR LACTOSYL PALMITATE SYNTHESIS

Indonesian Journal of Chemistry, 2010
Whey lactose can be esterified enzymatically by using immobilized lipase. The lipase can be isolated from Rhizopus oryzae, purified and immobilized in mesoporous aluminosilica. The use of immobilized lipase has advantages, there are longer shelf life and

Enhanced Esterification Activity and Thermostability of Imprinted Poly(Ethylene Glycol)-Lipase Complex [PDF]

Chemical and Biochemical Engineering Quarterly
Although the range of applications for enzymatic reactions in organic solvents is rapidly expanding, this study focused on the enzymatic activity in the esterification of lauric acid with benzyl alcohol, and thermostability of lipase using poly(ethylene ...

Preparation, Characterization, and Surface Modification of Cellulose Nanocrystal from Lignocellulosic Biomass for Immobilized Lipase

Fibers, 2022
This study reports the synthesis of cellulose nanocrystal (CNC) from sugarcane bagasse and rice straw as the matrix for immobilized lipase enzyme. The CNC surface was modified using cetyltrimethylammonium bromide (CTAB) to improve the interaction of CNC ...

Human milk lipases. I. Serum-stimulated lipase

Journal of Lipid Research, 1974
Lipase activity has previously been demonstrated in human milk. This study shows that there are two separate triglyceride lipases in human milk. One is mainly in the skim milk and is stimulated by bile salts; the other is mainly in the cream and is inhibited by bile salts but stimulated by serum.

Effect of Multiple Gene Copy Number of Bacterial Lipase to Increase Lipase Production in Pichia pastoris

Hayati Journal of Biosciences
Bacterial lipase poses potential challenges when expressed in eukaryotic protein expression systems such as Pichia pastoris. This research aims to increase extracellular T1.2RQ lipase secretion (free lipase) with multiple gene copy number strategies in ...

Digestion in vitro of erythritol esters by rat pancreatic juice enzymes

Journal of Lipid Research, 1972
The mechanism of the digestion of erythritol esters was determined using rat pancreatic juice and purified pancreatic lipase (EC 3.1.1.3). Conditions of hydrolysis were used that would selectively activate or inactivate nonspecific lipase or lipase.
