(Submitter supplied) Guar gum consists mainly of galactomannan, and constitutes the endosperm of guar seeds that acts as a reserve polysaccharide for germination. Due to its molecular structure and physical properties, this biopolymer has been considered as one of the most important and widely used gums in industry. However, for many of these applications this (hemi-)cellulosic structure needs to be modified or (partially) depolymerized in order to customize and improve its physicochemical properties. more...

(Submitter supplied) In this study, we compared the gene expression pattern of A. niger grown in liquid sugar beet pulp (SBP) at different time points, a by-product of the sugar industry that consists mainly of cellulose, xyloglucan, and pectin. Finally, we compared A. niger genetic response to liquid SBP to that of the same fungus when grown on solid SBP plates and polygalacturonic acid (PGA).

(Submitter supplied) Fungi are an important source of enzymes for saccharification of plant polysaccharides and production of biofuels. Understanding of the regulation and induction of expression of genes encoding these enzymes is still incomplete. To explore the induction mechanism, we analysed the response of the industrially important fungus Aspergillus niger to wheat straw, with a focus on events occurring shortly after exposure to the substrate. more...

(Submitter supplied) We have studied the physiological response of the fungus Aspergillus niger when exposed to wheat straw as a model lignocellulosic substrate. Using RNA-sequencing we showed that, 24 hours after exposure to straw, gene expression of known plant cell wall degrading enzymes represents a huge investment for the cells (about 20 % of the total mRNA). Our results also uncovered new esterases and surface interacting proteins that might form part of the fungal degradative arsenal. more...

(Submitter supplied) Background: Saprobic fungi are the predominant industrial sources of Carbohydrate Active enZymes (CAZymes) used for the saccharification of lignocellulose during the production of second generation biofuels. The production of more effective enzyme cocktails is a key objective for efficient biofuel production. To achieve this objective, it is crucial to understand the response of fungi to lignocellulose substrates. more...

(Submitter supplied) Saprotrophic fungi, such as Aspergillus niger, grow as mycelial colonies that are often considered uniform entities. To test this uniformity, we analyzed pie-slice sections of a colony grown on spatially separated substrates (glucose, wheat bran, sugar beet pulp) using transcriptomics, proteomics and metabolomics. The colony tuned its response to the local carbon source composition. Plant biomass degrading CAZymes and intracellular carbon catabolic enzymes were more abundant in parts of the colony containing the corresponding sugars. more...
