1. Castor polyurethane used as osteosynthesis plates: microstructural and thermal analysis
Abstract Bone fractures to be corrected need stabilization of their extremities, which is achieved with the use of plates and screws. This research aimed to produce castor bean polyurethane (Ricinus communis), to make resorbable plate, structural and thermal analysis. The production was made by the glycerolysis of the triglycerides present in the oil, after

2. Improving Yield of 1,3-Diglyceride by Whole-Cell Lipase from A. Niger GZUF36 Catalyzed Glycerolysis via Medium Optimization
1,3-Diglyceride (1,3-DG) has attracted considerable attention as a healthful food oil component. In this study, we reported a novel method to synthesis of 1,3-DG via glycerolysis of triglyceride (TG) catalyzed by whole-cell lipase from a new isolated strain, Aspergillus niger GZUF36. The glycerolysis products include major diglyceride and minor monoglyceride

3. Glicerólise de óleo de peixe catalisada por lipase comercial de Rhizomucor miehei em meio com surfactante de grau alimentício
Omega-3 enriched partial acylglycerols are beneficial for human health. The aim of this study was to obtain monoacylglycerols (MAG) and diacylglycerols (DAG) by means of glycerolysis of fish oil catalyzed by a lipase from Rhizomucor miehei in the presence of food grade surfactants (Tween 65, 80 or 85). Glycerolysis was successful in the reaction media for al

4. Enzymatic route selection for monoglyceride production using immobilized lipase on matrix obtained by sol-gel technique / Estratégias para desenvolvimento de um sistema operacional eficiente para a produção enzimática de monoglicerídeos
The objective of this project was to select the best enzymatic route to produce monoglycerides using lipase immobilized on matrix obtained by sol-gel technique, aiming to contribute for a better utilization of the glycerol generated as by-product in the biodiesel synthesis. For this purpose two methodologies were analyzed: (1) direct esterification of the gl

5. Produção de monoacilgliceróis e diacilgliceróis via glicerólise enzimática e destilação molecular
Monoacilglycerides and diacilglycerides are produced through lipase-catalyzed glycerolysis of soybean oil using Candida antarctica B in a solvent-free system. The reaction was carried out at a glycerol to triacylglycerol molar ratio of 8:1 with 2% of lipase. Acylglycerides, free fatty acids (FFA) and glycerol produced were separated employing the molecular d

6. Monoglicerídeos: produção por via enzimática e algumas aplicações
Monoglycerides (MAG) are non-ionic surfactants, widely used in the pharmaceutical, food and cosmetic industries. Although MAGs are manufactured on an industrial scale by chemical glycerolysis of oils and fats, new developments in lipase catalyzed synthesis have been studied as an alternative to the classical method seeking to use clean technology and green c

7. Obtenção de monoglicerideos de alta concentração atraves do processo de destilação molecular / Production of high concentration monoglycerides using molecular distillation process
Monoglicerídeos são emulsificantes amplamente utilizados em alimentos, fármacos e cosméticos. Industrialmente, são produzidos através da interesterificação de triglicerídeos com glicerol, a altas temperaturas (>200°C), na presença de catalisadores inorgânicos. Também conhecida como glicerólise, esta reação produz uma mistura com aproximadamen
