The beta-xylosidase of Thermomonospora.

Biotechnology and bioengineering, 2012
This study is concerned with characterizing cell-bound inducible beta-xylosidase produced by a strain of the thermophilic bacterial genus Thermomonospora. A crude preparation of this enzyme recovered from sonicated cells of this organism displayed high activity against paranitrophenyl-beta-xylopyranoside over a pH range of 5.5-7.7.

[Purification of exo-1,4-beta-xylosidase from Aspergillus niger 15].

Prikladnaia biokhimiia i mikrobiologiia, 1983
From the preparation of xylanase of the fungus Aspergillus niger 15 exo-1,4-beta-xylosidase was isolated by means of ethanol fractionation and chromatography on columns of Sephadex G-50, cellulose DE-52, Sephadex SP C-50, Sephadex G-200. The isolated enzyme (with the purification degree as calculated per protein 199, and yield with respect to activity ...

beta-Xylosidase from Aspergillus niger 15: purification and properties.

Journal of applied biochemistry, 1984
Homogeneous (as judged by data from gel filtration, ultracentrifugation, polyacrylamide gel electrophoresis with and without sodium dodecyl sulfate (SDS), and isoelectric focusing) beta-xylosidase showing beta-D-xylosidase, beta-D-glucosidase, beta-D-galactosidase, and alpha-L-arabinosidase activities has been isolated from the hemicellulase ...

[Properties of the exo-1,4-beta-xylosidase of Aspergillus niger 15].

Prikladnaia biokhimiia i mikrobiologiia, 1983
Properties of exo-1,4-beta-xylosidase from the fungus Aspergillus niger 15 were investigated. The enzyme was homogeneous during gel filtration, electrophoresis in polyacrylamide gel in the presence and absence of Na dodecyl sulfate, ultracentrifugation and isoelectric focusing.

Characterization of β-xylosidase enzyme from a Pichia stipitis mutant

Bioresource Technology, 2008
beta-Xylosidase production was maximal for the mutant Pichia stipitis NP54376 grown on xylan as the sole carbon source. beta-Xylosidase was purified from culture supernatant by (NH(4))(2)SO(4) precipitation and a hydrophobic interaction chromatography on phenyl sepharose. Optima of pH and temperature were 5.0 and 50 degrees C, respectively.

Immobilization and characterization of a thermostable β-xylosidase to generate a reusable biocatalyst

Enzyme and Microbial Technology, 2006
The thermostable beta-xylosidase from Sulfolobus solfataricus, expressed in Escherichia coli, was immobilized by entrapment into alginate with full recovery of activity and tested for xylose production from xylan hydrolysates. Since the recombinant activity was also cell bound, alginate beads entrapping E. coli whole cells were also prepared.

A Synthesis of Conduramine B and a 'Condurithiol', useful Molecules for Studying the Inhibition of β-Xylosidases

Australian Journal of Chemistry, 1999
Conduramine B and a ‘condurithiol’, namely (1 S ,2 S ,3 R ,6 R )-6-aminocyclohex-4-ene-1,2,3-triol and (1 R ,2 S ,3 R ,6 R )-6-sulfanylcyclohex-4-ene-1,2,3-triol, have been prepared by the thermal rearrangement of an acetimidate and a dithiocarbonate, respectively.

[Production of beta-xylosidase by the yeast Cryptococcus podzolicus].

Bioorganicheskaia khimiia, 2000
In studying the beta-xylosidase production by yeast Cryptococcus podzolicus (Basidiomycetes), it was shown to be an inducible secretory enzyme. Xylooligosaccharides generated from xylan and methyl beta-xyloside were found to induce the beta-xylosidase synthesis.

[Transglycosylation reactions catalyzed by Aspergillus niger 15 beta-xylosidase].

Prikladnaia biokhimiia i mikrobiologiia, 1984
The products of transglycosylation formed as a result of action of beta-xylosidase from Aspergillus niger 15 on p-nitrophenyl-beta-D-glucopyranoside and p-nitrophenyl-beta-D-xylopyranoside were studied by means of chromatography on sephadexes. They are formed at the substrate concentration of 10--100 mM with the amount 7--10 times less than that of ...
