Green coconut fiber, a lignocellulosic material native from Brazilian northeast coast, was chemically treated by three methods: NaOCl, NaOCl/NaOH or H2O2. The effect of these treatments on the structure, composition and properties fibers studied using SEM, FTIR, XPS, TGA other analyses. SEM showed that treatment with H2O2 is most efficient in terms waxy fatty acid residues removal but it does not modify surface chemical composition, can be seen FTIR wettability results. analyses revealed...
Microalgae have the ability to grow rapidly, synthesize and accumulate large amounts (approximately 20–50% of dry weight) lipids. A successful economically viable algae based oil industry depends on selection appropriate algal strains. In this study ten species microalgae were prospected determine their suitability for production: Chaetoceros gracilis, mulleri, Chlorella vulgaris, Dunaliella sp., Isochrysis Nannochloropsis oculata, Tetraselmis chui, tetrathele Thalassiosira weissflogii. The...
ABSTRACT In this review, we present an overview of the different renewable polymers that are currently being used as matrixes for enzyme immobilization and their properties new developments in biocatalysts preparation applications. Polymers obtained from resources have attracted much attention recent years because they environmentally friendly available large quantities natural sources. Different methods enzymes with these reviewed, particular: (1) binding to a prefabricated biopolymer, (2)...
DVS supports are very suitable to stabilize enzymes<italic>via</italic>multipoint covalent attachment.
Novozyme 435, which is a commercial immobilized lipase B from Candida antarctica (CALB), has been proven to be inadequate for the kinetic resolution of rac‐indanyl acetate. As it previously described that different immobilization protocols may greatly alter features, in this work, CALB was covalently on epoxy Immobead‐350 (IB‐350) and glyoxyl‐agarose ascertain if better would result. Afterwards, all biocatalysts were utilized hydrolytic rac ‐indanyl acetate ‐(chloromethyl)‐2‐( o...
In this communication, lipase A from Candida antarctica (CALA) was immobilized by covalent bonding on magnetic nanoparticles coated with chitosan and activated glutaraldehyde, labelled CALA-MNP, (immobilization parameters: 84.1% ± 1.0 for immobilization yield 208.0 3.0 U/g 1.1 derivative activity). CALA-MNP biocatalyst characterized X-ray Powder Diffraction (XRPD), Fourier Transform Infrared (FTIR) spectroscopy, Thermogravimetry (TG) Scanning Electron Microscope (SEM), proving the...
The lipase from Pseudomonas fluorescens (PFL) has been immobilized on octyl-agarose beads under 16 different conditions (varying pH, ionic strength, buffer, adding some additives) at two loadings, 1 and 60 mg of enzyme/g support with the objective check if this can alter biocatalyst features. activity biocatalysts versus p-nitrophenyl butyrate triacetin their thermal stability were studied. immobilization produced very Considering extreme cases, using mg/g preparations, PFL changed more than...
NiZnFe2O4 superparamagnetic nanoparticles were coated with silica by impregnation tetraethoxysilane (TEOS) and further activated divinylsulfone (DVS) p-benzoquinone (BQ) for covalent immobilization lipase from Pseudomonas fluorescens (PFL), producing the biocatalysts TEOS-NANO-DVS-PFL TEOS-NANO-BQ-PFL. The optimal conditions enzyme found to be pH 7 0.1 M of both activating reagents. PFL was also immobilized on TEOS without any activation as a reference (TEOS-NANO-PFL). Results indicated that...
