The gene xylE encoding endo-1,4-β-xylanase from the 10th family of glycosyl hydrolases produced by the mycelial fungus Penicillium canescens has been expressed under the control of the strong promoter of the bgaS gene encoding β-galactosidase from P. canescens. As a result, a strain-producer of endoxylanase XylE was developed. The recombinant enzyme was(More)
The genes inuA and inu1, encoding two inulinases (32nd glycosyl hydrolase family) from filamentous fungi Aspergillus niger and A. awamori, were cloned into Penicillium canescens recombinant strain. Using chromatographic techniques, endoinulinase InuA (56 kDa, pI 3) and exoinulinase Inu1 (60 kDa, pI 4.3) were purified to homogeneity from the enzymatic(More)
Genes of β-mannosidase 97 kDa, GH family 2 (bMann9), β-mannanase 48 kDa, GH family 5 (bMan2), and α-galactosidase 60 kDa, GH family 27 (aGal1) encoding galactomannan-degrading glycoside hydrolases of Myceliophthora thermophila C1 were successfully cloned, and the recombinant enzymes were purified to homogeneity and characterized. bMann9 displays only(More)
CONCLUSION This p:aper extends the known area of pre-European fires and the dating of a major, fire elucidates some aspects of the forest dynamics of the Northern Tararuas. Although only the Tiritea catchment has been studied in detail, this same fire, or another in the sa'me period, apparently swept much of the Ot,mgaue, Kahuterawa and Tokomaru(More)
The effect of polysaccharide monooxygenase (endoglucanase IV) from the fungus Trichoderma reesei on the hydrolysis of polysaccharide substrates by cellulases secreted by the fungus Penicillium verruculosum has been investigated. Supplementation of the enzyme complex from P. verruculosum by endoglucanase IV from T. reesei has been shown to elevate the(More)
Here we report the first isolation to homogeneous forms of two glucoamylases from the fungus Penicillium verruculosum and their study in comparison with known glucoamylases from Aspergillus awamori and Aspergillus niger. Genes that encode glucoamylases from P. verruculosum were cloned and expressed in the fungus Penicillium canescens, and the recombinant(More)
An enzyme preparation has been produced on the basis of Penicillium canescens strains with the activity of cellibiohydrolase I, II; endo-1,4-β-gluconase of Penicillium verruculosum; and β-glucosidase of Aspergillus niger. It was shown that for the most effective hydrolysis of aspen wood pulp the optimal ratio of cellobiohydrolase and endo-1,4-β-gluconase in(More)
Methods for the production and analysis of cellulase and hemicellulase enzyme preparations of various compositions based on the Penicillium verruculosum carbohydrase complex and intended for the effective hydrolysis of different types of cellulose-containing materials (CCMs) have been developed. New recombinant strains of P. verruculosum producing(More)
The genes of endoglucanases EG2 (36.2 kDa) Penicillium verruculosum and LAM (30.8 kDa) Myceliophthora thermophila were cloned in P. verruculosum recombinant strain. New enzyme preparations with highly stable activity against β-glucan and laminarin were obtained and investigated, homogeneous enzymes EG2 (EC 3.2.1.4) and LAM (EC 3.2.1.6) being purified and(More)
Complex enzymatic preparations demonstrating activities homologous to pectinlyase A and heterologous to endo-1,4-β-glucanase from Penicilliumverruculosum and β-glycosidase from Aspergillusniger have been obtained on the basis of recombinant strains of the fungus Penicilliumcanescens. Two approaches were utilized: development of an enzymatic preparation on(More)
