Journal ArticleDOI
Genomic and secretomic analyses reveal unique features of the lignocellulolytic enzyme system of Penicillium decumbens.
Guodong Liu,Lei Zhang,Xiaomin Wei,Gen Zou,Yuqi Qin,Liang Ma,Jie Li,Huajun Zheng,Shengyue Wang,Chengshu Wang,Luying Xun,Luying Xun,Guoping Zhao,Guoping Zhao,Zhihua Zhou,Yinbo Qu +15 more
TL;DR: Comparative genomics analysis with the phylogenetically most similar species Penicillium chrysogenum and proteomic analysis of secretomes revealed that P. decumbens has evolved with more genes involved in plant cell wall degradation, but fewer genes in cellular metabolism and regulation.
Journal ArticleDOI

TL;DR: ClrB was identified as focal point for the synergistic activation regulation of cellulase expression by integrating cellulolytic regulators and their target genes, which refined the understanding of transcriptional-regulatory network as a “seesaw model” in which the coordinated regulation ofCellulase genes is established by counteracting activators and repressors.
Journal ArticleDOI
Engineering endoglucanase II from Trichoderma reesei to improve the catalytic efficiency at a higher pH optimum.
TL;DR: More stable helixes and changed electrostatic interactions between the catalytic residues and substrates may explain the higher activities and higher pH optima of the variants of Trichoderma reesei endo-beta-1,4-glucanase II.
Journal ArticleDOI
Isolation and characterization of a β-glucosidase from Penicillium decumbens and improving hydrolysis of corncob residue by using it as cellulase supplementation
TL;DR: The purified enzyme could improve the saccharifying ability of cellulose when it was added to the cellulase systems of Trichoderma reesei QM 9414 and has great potential to be utilized as supplementation in conversion of corncob residue and other lignocellulosic biomass into simple sugars.
Journal ArticleDOI
Development of highly efficient, low-cost lignocellulolytic enzyme systems in the post-genomic era.
TL;DR: A general strategy for lignocellulolytic enzyme system development is proposed, including the improvement of the hydrolysis efficiencies and productivities of current enzyme systems.
