Profiling of the β-glucosidases identified in the genome of : insights from genomics, transcriptomics, proteomics, and homology-modeling studies.

The enzymatic conversion of lignocellulosic biomass to bioethanol depends on efficient enzyme systems with β-glucosidase as one of the key components. In this study, we performed in-depth profiling of the various β-glucosidases present in the genome of the hypercellulolytic fungus using genomics, transcriptomics, proteomics, and molecular dynamics simulation approaches. Of the eight β-glucosidase genes identified in the genome, three were predicted to be extracellular based on signal peptide prediction and abundance in the secretome.

Characterization of a GH5 endoxylanase from Penicillium funiculosum and its synergism with GH16 endo-1,3(4)-glucanase in saccharification of sugarcane bagasse.

The production of second-generation fuels from lignocellulosic residues such as sugarcane bagasse (SCB) requires the synergistic interaction of key cellulose-degrading enzymes and accessory proteins for their complete deconstruction to useful monomeric sugars. Here, we recombinantly expressed and characterized unknown GH5 xylanase from P. funiculosum (PfXyn5) in Pichia pastoris, which was earlier found in our study to be highly implicated in SCB saccharification.

Accessory enzymes of hypercellulolytic Penicillium funiculosum facilitate complete saccharification of sugarcane bagasse.

Background: Sugarcane bagasse (SCB) is an abundant feedstock for second-generation bioethanol production. This complex biomass requires an array of carbohydrate active enzymes (CAZymes), mostly from filamentous fungi, for its deconstruction to monomeric sugars for the production of value-added fuels and chemicals. In this study, we evaluated the repertoire of proteins in the secretome of a catabolite repressor-deficient strain of Penicillium funiculosum, PfMig1, in response to SCB induction and examined their role in the saccharification of SCB.

Antidiabetic potentials of essential oil extracted from the leaves of Hoslundia opposita Vahl.

This study was aimed at assessing the potential of essential oil from the leaf of Hoslundia opposita in the treatment of diabetes. Forty-eight rats (Rattus norvegicus) were randomized into two groups; nondiabetic and diabetic groups, each with four subgroups. Animals in the diabetic group were induced with diabetes using a single dose of alloxan monohydrate, 160 mg/kg body weight (b.
