Biochemical properties of free and immobilized Candida viswanathii lipase on octyl-agarose support: Hydrolysis of triacylglycerol and soy lecithin
(2018-02-01)
Microbial lipases are important enzymes in food and pharmaceutical industries. In this work, a Candida viswanathii lipase was purified by hydrophobic interaction chromatography on octyl Sepharose. The purification presented ...
Immobilization and Stabilization of Beta-Xylosidases from Penicillium janczewskii
(2017-05-01)
β-Xylosidases are critical for complete degradation of xylan, the second main constituent of plant cell walls. A minor β-xylosidase (BXYL II) from Penicillium janczewskii was purified by ammonium sulfate precipitation (30% ...
Purification, characterization, and specificity determination of a new serine protease secreted by penicillium waksmanii
(2013-01-01)
The purpose of this work was to purify a protease from Penicillium waksmanii and to determine its biochemical characteristics and specificity. The extracellular protease isolated that was produced by P. waksmanii is a ...
Characterization of a glucose- and solvent-tolerant extracellular tannase from Aspergillus phoenicis
(2013-01-01)
Tannases have attracted wider attention because of their biotechnological potential, especially enzymes from filamentous fungi and other microorganisms. However, the biodiversity of these microorganisms has been poorly ...
Nanodevices for the immobilization of therapeutic enzymes
(Taylor & Francis, 2016-05)
Therapeutic enzymes are one of the most promising applications of this century in the field of pharmaceutics. Biocatalyst properties can be improved by enzyme immobilization on nano-objects, thereby increasing stability ...
Homogeneous Biocatalysis in Organic Solvents and Water-Organic Mixtures
(Taylor & Francis, 2003-12)
Biocatalysis in non-aqueous media has undergone tremendous development during the last decade, and numerous reactions have been introduced and optimized for synthetic applications. In contrast to aqueous enzymology, ...
Purification and characterization of xylanases from Aspergillus giganteus
(2004-04-20)
A strain of Aspergillus giganteus cultivated in a medium with xylan produced two xylanases (xylanase I and II) which were purified to homogeneity. Their molar mass, estimated by SDS-PAGE, were 21 and 24 kDa, respectively. ...
Production and partial characterization of keratinase produced by a microorganism isolated from poultry processing plant wastewater
(2008-02-05)
A Streptomyces was isolated from poultry plant wastewater, showed high keratinolytic activity when cultured on feather meal medium. Optimum keratinolytic activity was observed at 40°C and pH 8.0. The enzyme also showed to ...
Xylanase and β-Xylosidase from Penicillium janczewskii: Production, Physico-Chemical properties, and application of the crude extract to pulp biobleaching
(2013-02-01)
Extracellular xylanase and β-xylosidase production by a Penicillium janczewskii strain were investigated in liquid cultures with xylan from oat spelts under different physical and chemical conditions. The selected conditions ...
Modelling thermal stability and activity of free and immobilized enzymes as a novel tool for enzyme reactor design
