Immobilization of lipase from Penicillium sp. section Gracilenta (CBMAI 1583) on different hydrophobic supports: Modulation of functional properties
(2017-01-01)
Lipases are promising enzymes that catalyze the hydrolysis of triacylglycerol ester bonds at the oil/water interface. Apart from allowing biocatalyst reuse, immobilization can also affect enzyme structure consequently ...
Synthesis and characterization of acrylamide/acrylic acid hydrogels crosslinked using a novel diacrylate of glycerol to produce multistructured materials
(2014)
We grew Rhizopus microsporus CPQBA 312-07 DRM in solid-state fermentation on a 1:1 mixture, by mass, of sugarcane bagasse and sunflower seed meal, to produce a fermented solid containing lipases (tricaprylin-hydrolyzing ...
Estudo da produção de biodiesel utilizando etanol e óleo de soja ou de macaúba, catalisada por lipase de mamona e de Thermomyces lanuginosus
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2015-02-27)
Biodiesel, a fuel produced from renewable sources, is a sustainable substitute to meet the growing global energy demand. The transesterification (alcoholysis) of oils and fats is the route most used in biodiesel synthesis, ...

The Employment of a Removable Chitosan-Derivatized Polymeric Sensitizer in the Photooxidation of Polyhydroxylated Water-Pollutants
(Wiley Blackwell Publishing, Inc, 2014-01)
The known O2(1∆g)-sensitizer system Chitosan bounded Rose Bengal (CH-RB), with Rose Bengal (RB) immobilized by irreversible covalent bonding to the polymer Chitosan (CH), soluble in aquous acidic medium, was employed in ...
