TL;DR: The influence of fermentation conditions on the component composition of secreted enzyme complexes was revealed and the characteristic features of enzyme preparations obtained in “cellulase’ and “xylanase” fermentation conditions are shown.
Journal ArticleDOI
New cellulases efficiently hydrolyzing lignocellulose pulp
A. A. Skomarovsky,Alexander V. Markov,Alexander V. Gusakov,E. G. Kondrat’eva,Oleg N. Okunev,A. O. Bekkarevich,V. Yu. Matys,Arkady P. Sinitsyn +7 more
TL;DR: Commercial and pilot enzyme preparations from fungi of the genera Penicillium and Trichoderma have been compared with regard to their action on conifer wood pretreated with acidified aqueous ethanol (organosolve).
Journal ArticleDOI
Properties of hemicellulases of the enzyme complex from Trichoderma longibrachiatum
Alexander V. Markov,Alexander V. Gusakov,Dzedzyulya Ei,Boris B. Ustinov,A. A. Antonov,Oleg N. Okunev,A. O. Bekkarevich,Arkady P. Sinitsyn +7 more
TL;DR: Six xylan-hydrolyzing enzymes have been isolated from the preparations Celloviridin G20x and Xybeten-Xyl, obtained earlier based on the strain 1 Trichoderma longibrachiatum, and synergistic effects on arabinoxylan cleavage were studied.
Journal ArticleDOI
Production of enzyme preparations on the basis of Penicillum canescens recombinant strains with a high ability for the hydrolysis of plant materials
P.V. Volkov,Alexandra M. Rozhkova,A. G. Pravil’nikov,R M Andrianov,G.S. Dotsenko,A. O. Bekkarevich,A. V. Koshelev,Oleg N. Okunev,Ivan N. Zorov,Arkady P. Sinitsyn +9 more
TL;DR: 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 enzyme preparations was 8: 2 (by protein).
Journal ArticleDOI
Isolation and properties of cellobiase from Penicillium verruculosum
Ivan N. Zorov,Alexander V. Gusakov,V. A. Baraznenok,A. O. Bekkarevich,Oleg N. Okunev,Arkady P. Sinitsyn,E. G. Kondrat’eva +6 more
TL;DR: Kinetic parameters of enzymatic hydrolysis of cellobiose, gentiobioses, sophorose, and synthetic substrates, i.
