Effect of immobilization on pH and thermal stability of Aspergillus ficuum phytase
Enzyme and Microbial Technology, 1999Abstract The phytase from Aspergillus ficuum catalyzes the hydrolysis of phytic acid into phosphoric acid and myo -inositol. The activity of this enzyme was determined by monitoring the rate of inositol production using high-performance liquid chromography methodology. The maximum activity of the enzyme was found to be approximately pH 5 and had a

PhyA gene product of Aspergillus ficuum and Peniophora lycii produces dissimilar phytases
Biochemical and Biophysical Research Communications, 2003PhyA gene products of Aspergillus ficuum (AF) and Peniophora lycii (PL) as expressed in industrial strains of Aspergillus niger and Aspergillus oryzae, respectively, were purified to homogeneity and then characterized for both physical and biochemical properties. The PL phytase is 26 amino acid residues shorter than the AF phytase.

Hydrolysis of inulin: A kinetic study of the reaction catalyzed by an inulinase from Aspergillus ficuum [PDF]
Biotechnology and Bioengineering, 1991 AbstractA kinetic study of the hydrolysis of inulin was performed by using as catalyst a commercial inulinase from Aspergillus ficuum. The reaction was studied carrying out initial rate as well as time course measurements. Both inulinase and invertase activities of the enzyme were taken into account, and the corresponding kinetic parameters were ...

Mycoremediation of pretilachlor and its metabolite by Aspergillus ficuum
Journal of Environmental Science and Health, Part B, 2023Pretilachlor is one of the widely used chloroacetamide herbicides in Asian countries to control weeds in the rice field. The extensive use of herbicides has caused major concern among scientists throughout the world. Therefore, it is essential to develop an efficient method for the remediation of pretilachlor and its harmful by-products from ...

Controlled Production of Fructose by an Exoinulinase from Aspergillus Ficuum
Applied Biochemistry and Biotechnology, 2009An exoinulinase has been isolated, purified and characterised from a commercially available broth of Aspergillus ficuum. The enzyme was purified 4.2-fold in a 21% yield with a specific activity of 12,300 U mg(-1)(protein) after dialysis, ammonium sulphate fractionation and Sephacryl S-200 size exclusion and ion exchange chromatography.

Production of inulooligosaccharides by endoinulinases from Aspergillus ficuum
Food Research International, 2005Inulooligosaccharide (IOS) production from inulin was studied using a partially purified endoinulinase and a purified endoinulinase, which originated from Aspergillus ficuum. At the optimal conditions, including 50 g/L inulin, an enzyme concentration of 10 U/g substrate, 45 °C, and pH 6.0, the inulin-degrading degree by partially purified endoinulinase

Vinegar production residue as substrates for phytase production by Aspergillus ficuum
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2009Two kinds of vinegar production residues, sorghum vinegar residue (SVR) and corn vinegar residue (CVR), were used as a substrate for phytase production in solid-state fermentation (SSF) by Aspergillus ficuum. Various process parameters influencing phytase production were evaluated by single factor design experiments; further study ...

Immobilization ofAspergillus FicuumPhktase: Product Characterization of this Bioreactor
Preparative Biochemistry, 1988Aspergillus ficuum phytase was covalently immobilized on Fractogel TSK HW-75 containing 2-oxy-l-alkylpyridinium salts. A packed-bed bioreactor was constructed with the immobilized phytase. An HPLC ion-exchange method was used to analyze the enzymatic products of the bioreactor. Immobilized fungal phytase was able to hydrolyze myo-inositol Hexa-, penta-,

Expression of the INU2 gene for an endoinulinase of Aspergillus ficuum in Saccharomyces cerevisiae
Biotechnology Letters, 1999The INU2 gene encoding an endoinulinase of Aspergillus ficuum was expressed by the Kluyveromyces marxianus INU1 promoter in a SUC2-deleted Saccharomyces cerevisiae to produce the endoinulinase preparation free of an exoinulinase and an extracellular invertase in the culture medium. A recombinant yeast strain produced the sufficient amount of the enzyme
