title: [Transglycosylation reactions catalyzed by Aspergillus niger 15 beta-xylosidase].
abstract: 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 hydrolysis products. Peculiarities of chromatography of substrates, products of transglycosylation and p-nitrophenol on Sephadexes G-15 and G-25 were analysed.
