Thermoinactivation of β-xylosidase immobilized on nylon

1998
Abstract β-xylosidase was isolated and partially purified from Trichoderma reesei QM 9414 grown on wheat straw as the sole carbon source. The enzyme was attached covalently to nylon powder and thermoinactivation was carried out at temperatures between 55 and 75° C.

Research progress of β-xylosidase in green synthesis

International Journal of Biological Macromolecules
β-Xylosidase, an important hydrolase, catalyzes the degradation of xylan and xylosides, demonstrating significant potential for applications in biomass conversion and green synthesis. In recent years, with the rise of green chemistry, research on β-xylosidase in sustainable chemical synthesis has garnered increasing attention.

Regulation of ?-xylosidase formation by xylose in Trichoderma reesei

Applied Microbiology and Biotechnology, 1995
The soft-rot fungus Trichoderma reesei forms β-xylosidase (EC 3.2.1.37) activity during cultivation on xylan and xylose, but not on glucose. When mycelia precultivated on glycerol were washed and transferred to fresh medium without a carbon and nitrogen source, β-xylosidase formation was induced by xylan, xylobiose and xylose.

The β‐xylosidase of Thermomonospora

Biotechnology and Bioengineering, 1985
AbstractThis study is concerned with characterizing cell‐bound inducible β‐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‐β‐xylopyranoside over a pH range of 5.5‐7.7.

Xylanases and β-xylosidase of Trichoderma liǵnorum

1988
Publisher Summary Trichoderma lignorum is a rich source of various extracellular polyand oligosaccharide-degrading enzymes—for example, xylanases, cellulase, amyloglucosidase, β-xylosidasey α-arabinosidase, and β-glucosidase. This chapter describes a simple procedure for the purification of two different xylanases, 1,4-β-D-xylan xylanohydrolase and a

Research Progress Concerning Fungal and Bacterial β-Xylosidases

Applied Biochemistry and Biotechnology, 2015
In the present review, we briefly summarize the biotechnological applications of microbial β-xylosidases in the processing of agro-industrial residues into fuels and chemicals and report the importance of using immobilization techniques to study the enzyme.

Biochemical properties of a beta-xylosidase from Clostridium cellulolyticum

Applied and Environmental Microbiology, 1995
A 43-kDa beta-xylosidase from Clostridium cellulolyticum was purified to homogeneity. The enzyme releases xylose from p-nitrophenylxylose and xylodextrins with a degree of polymerization ranging between 2 and 5. The N-terminal amino acid sequence of the enzyme showed homologies with three other bacterial beta-xylosidases.

The β-xylosidase production by yeastCryptococcus podzolicus

Russian Journal of Bioorganic Chemistry, 2000
In studying the β-xylosidase production by yeastCryptococcus podzolicus (Basidiomycetes), it was shown to be an inducible secretory enzyme. Xylooligosaccharides generated from xylan and methyl β-xyloside were found to induce the β-xylosidase synthesis.

Preparation and application of a fluorogenic substrate for endo-β-xylosidase

Journal of Biochemical and Biophysical Methods, 1989
The present paper describes a fluorometric assay for galactosaminoglycan-degrading endo-beta-xylosidase, utilizing glycosaminoglycan chains bearing a 4-methylumbelliferyl group at the reducing terminus as a substrate. This fluorogenic substrate is synthesized by human skin fibroblasts cultured in the presence of a fluorogenic xyloside, 4 ...

Engineering lower inhibitor affinities in β-d-xylosidase

Applied Microbiology and Biotechnology, 2009
Beta-D-Xylosidase catalyzes hydrolysis of xylooligosaccharides to D-xylose residues. The enzyme, SXA from Selenomonas ruminantium, is the most active catalyst known for the reaction; however, its activity is inhibited by D-xylose and D-glucose (K (i) values of approximately 10(-2) M).
