1. Optimizing culture conditions for production of intra and extracellular inulinase and invertase from Aspergillus niger ATCC 20611 by response surface methodology (RSM)
Abstract The aim of this study was obtain a model that maximizes growth and production of inulinase and invertase by Aspergillus niger ATCC 20611, employing response surface methodology (RSM). The RSM with a five-variable and three-level central composite design (CCD) was employed to optimize the medium composition. Results showed that the experimental data

2. Purification of inulinases by changing the ionic strength of the medium and precipitation with alcohols
ABSTRACT The present study evaluated the purification of inulinase by changing the ionic strength of the medium by addition of NaCl and CaCl2 followed by precipitation with n-propyl alcohol or iso-propyl alcohol. The effects of the concentration of alcohols and the rate of addition of alcohols in the crude extract on the purification yield and purification f

3. Preparation of Zinc Tungstate (ZnWO4) Particles by Solvo-hydrothermal Technique and their Application as Support for Inulinase Immobilization
ZnWO4 particles were synthesized as a single-phase by a simple and easy solvo-hydrothermal technique using water-ethylene glycol mixture as solvent, without using surfactant. Physical properties of produced particles were analyzed by X-ray diffraction (XRD), infrared spectroscopy (FTIR), surface area (BET), particles size distribution and atomic force micros

4. Production of Copper and Cobalt Aluminate Spinels and Their Application As Supports for Inulinase Immobilization
AbstractCopper and cobalt aluminates were obtained through the use of chitosan as template. In this synthesis route, chitosan is eliminated by heating, and a porous material is produced. These oxides were used as supports for inulinase immobilization by adsorption process. Physical properties of produced particles were analyzed by X-ray diffraction (XRD) and

6. Production of Inulinase by Free and Immobilized Cells of Penicillium funiculosum p.36
The aim of this work was to optimize the growth conditions and continuous production of the enzyme using free and immobilized cells of inulinase by Penicillium funiculosum. The highest yield of enzyme (163.5U/mL) was obtained when the culture was incubated at 27oC and 200 rpm for 96h in a fermentation medium containing both inulin and peptone as sole carbon

7. Estudos sobre as propriedades catalíticas da frutosiltransferase de Rhodotorula sp. livre e imobilizada em suporte inorgânico / Catalytic properties of fructosyltransferase from Rhodotorula sp., free and immobilized on inorganic support
A obtenção de fruto-oligossacarídeos (FOS), um açúcar prebiótico de vasta aplicação industrial, por enzimas imobilizadas abrange dois conceitos em grande expansão: aplicação industrial de enzimas imobilizadas e alimentos funcionais. A partir de flores da Mata Atlântica Brasileira uma cepa foi isolada e identificada como Rhodotorula sp. LEB-V10 e

8. Partial characterization of an inulinase produced by Aspergillus japonicus URM5633
Enzymes obtained by fermentation processes offer a number of advantages and have been widely researched and used throughout the world. This study aimed to partially characterise an inulinase produced from palm and cassava peel. The enzyme was produced via the solid-state fermentation of Aspergillus japonicus URM5633. The optimal temperatures were 50ºC and 5

9. Production, characterization and application of inulinase from fungal endophyte CCMB 328
A enzima inulinase (EC 3.2.1.7, β-D-frutano frutanohidrolase) atua sobre as ligações β-2,1 da inulina, um polifrutano consistindo de frutose unida por ligações β-2,1. A hidrólise de inulina através do uso de inulinase é uma alternativa viável para a obtenção de xarope de frutose. O objetivo deste trabalho foi estudar a produção, caracterizaç�

11. Production of inulinase from Kluyveromyces marxianus using Dahlia tuber extract
Various carbon sources were evaluated for production of inulinase by yeast, Kluyveromyces marxianus MTCC 3995. Highest inulinase activity was observed with Dahlia extract (25.3 nkat mL-1) as carbon source. The enzyme activity was 1.4 folds higher than that observed in media containing pure chicory inulin (17.8 nkat mL-1). The yeast showed good growth on a si

12. Comparative study of two purified inulinases from thermophile Thielavia Terrestris NRRL 8126 and mesophile Aspergillus Foetidus NRRL 337 grown on Cichorium Intybus l
Thirty fungal species grown on Cichorium intybus L. root extract as a sole carbon source, were screened for the production of exo-inulinase activities. The thermophile Thielavia terrestris NRRL 8126 and mesophile Aspergillus foetidus NRRL 337 gave the highest production levels of inulinases I & II at 50 and 24 ºC respectively. Yeast extract and peptone were
