Synthesis of Activity Probes for β-Xylosidase

Journal of the Chinese Chemical Society, 2006
Due to their industrial interest and significance, developing a rapid method for screening β-xylosidase activities would certainly facilitate the research and improve production in xylan-related industries especially in the pulp and paper industries. Here we report the synthesis of two activity probes, LCL-6X and -12X, for β-xylosidase. They both carry

β-Xylosidase Recovery by Reversed Micelles

Applied Biochemistry and Biotechnology, 2000
β-Xylosidase, an enzyme produced by Penicillium janthinellum fungus, was prepurified by fractionated precipitation with ethanol and extracted by reversed micelles of N-benzyl-N-dodecyl-N-bis(2-hydroxyethyl) ammonium chloride (BDBAC) cationic surfactant.

Production of β-Xylosidase Activity by Trichodermaharzianum Strains

Current Microbiology, 1996
Nine Trichoderma harzianum strains were screened for beta-xylosidase activity when grown in solid-state cultures on media containing wheat bran as the carbon source. All strains produced beta-xylosidase activity, the most active being in extracts of cultures of T. harzianum strain 4.

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 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.

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.

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.

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.

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.
