The Specificity of Interactions between Endoinulinase from Aspergillus ficuum and Mono-, Di-, and Polysaccharides

Biophysics, 2023
The aim of this study was to analyze the peculiarities of spatial organization of an endoinulinase molecule from Aspergillus ficuum after its binding to mono-, di-, and polysaccharides. This study examined changes in volume and number of internal cavities upon binding of inulinase to mono- (glucose, fructose), di- (sucrose, mannose), and ...

Malformins from Aspergillus ficuum, A. awam ori and A. phoenicis

Phytochemistry, 1969
Abstract Malformins were isolated from culture filtrates of Aspergillus ficuum, A. awamori and A. phoenicis . They were characterized as malformin A (a mixture of malformins A 1 and A 2 ) on the basis of biological activity, chromatographic behavior, i.r. and mass spectrum, optical rotation and amino acid analysis.

Enhanced Aspergillus ficuum phytase production in fed-batch and continuous fermentations in the presence of talcum microparticles [PDF]

Bioprocess and Biosystems Engineering, 2015
This study aimed to enhance Aspergillus ficuum phytase production in fed-batch and continuous fermentations with addition of talcum microparticles. Phytase activity almost doubled in fed-batch and continuous fermentations by addition of 15 g/l of talcum ...

Aspergillus ficuum Phytase: Complete Primary Structure Elucidation by Chemical Sequencing

Biochemical and Biophysical Research Communications, 1993
The primary structure of Aspergillus ficuum phytase was deduced from overlaps in peptide sequences. The unglycosylated enzyme is a 441 residue protein with a molecular mass of 48.5-KDa, as calculated from the total covalent structure. The estimated pl of the protein is about 4.76. Of the 19 Asn residues, 9 were found to be glycosylated.

Purification, properties and comparison of invertase, exoinulinases and endoinulinases of Aspergillus ficuum

Applied Microbiology and Biotechnology, 1987
One invertase (Inv), five exoinulinases (Exo I; II; III; IV; V) and three endoinulinases (Endo I; II; III) were isolated from a commercial inulinase preparation derived from Aspergillus ficuum using ammonium sulfate precipitation, ion exchange chromatography on DEAE-Sephacel and DEAE-Trisacryl, gel filtration on Ultrogel and Fast Protein Liquid ...

Immobilization ofAspergillus ficuumInulinases on Porous Glass

Biocatalysis, 1992
The thermostable inulinases from the fungus Aspergillus ficuum were immobilized by covalent binding on porous glass beads of different porosities (pore diameter 125 to 1170 A). The highest retention of activity (60%) and highest activity per g of support (300 IU/g) were obtained with the support with an average pore diameter of 120 A.

Production and Partial Purification of Tannase fromAspergillus ficuumGim 3.6

Preparative Biochemistry and Biotechnology, 2014
A novel fungal strain, Aspergillus ficuum Gim 3.6, was evaluated for its tannase-producing capability in a wheat bran-based solid-state fermentation. Thin-layer chromatography (TLC) analysis revealed that the strain was able to degrade tannic acid to gallic acid and pyrogallol during the fermentation process.

Decolorization of Direct Black 22 by Aspergillus ficuum.

Journal of environmental sciences (China), 2002
The decolorization of Direct Black 22 by Aspergillus ficuum has been studied. It was found that Aspergillus ficuum could effectively decolorize Direct Black 22 especially when grown as pelleted mycelia. Results showed that the media containing Direct Black 22 at 50 mg/L could be decolorized by 98.05% of the initial color in 24 h.

An Acid Phosphatase from Aspergillus ficuum Has Homology to Penicillium chrysogenum PhoA

Biochemical and Biophysical Research Communications, 1994
Three secreted acid phosphatases had previously been characterized from Aspergillus ficuum grown under conditions of limited phosphate. One of these could not be readily separated from AFPhyB, a pH 2.5 optimum acid phosphatase with phytase activity.
