The determination of ferulic acid in sugar beet pulp

The fermentation of sugar-beet pulp silage.

Fungal secretomes enhance sugar beet pulp hydrolysis

The recalcitrance of lignocellulose makes enzymatic hydrolysis of plant biomass for the production of second generation biofuels a major challenge. This work investigates an efficient and economic approach for the enzymatic hydrolysis of sugar beet pulp (SBP), which is a difficult to degrade, hemicellulose-rich by-product of the table sugar industry. Three fungal strains were grown on different...

Formation of ferulic acid dehydrodimers through oxidative cross-linking of sugar beet pectin

Pectins isolated from sugar beet pulp by autoclaving contained significant amounts of ferulates, 8.8% of which were ferulate dehydrodimers. The 8-8 and 8-0-4 dehydrodimers were predominant. Oxidative cross-linking with hydrogen peroxide/peroxidase lowered the amount of ferulic acid by 78%, while an increase in ferulate dehydrodimers by a factor of 4.9 was observed. The highest increase was seen...

Isolation from sugar beet cell walls of arabinan oligosaccharides esterified by two ferulic acid monomers.

Side chains of sugar beet (Beta vulgaris) pectins, which are mainly composed of arabinose (Ara) and galactose (Gal) residues, are esterified by ferulic acid units. Enzymatic hydrolysis of beet cell walls yielded several feruloylated oligosaccharides, which were separated by hydrophobic interaction chromatography. Two new oligomers were isolated in the fraction eluted by 25:75 (v/v) ethanol:wate...

Cellulase Production by Trichoderma reesei using Sugar Beet Pulp

Cellulase production by the fungus Trichoderma reesei was studied using sugar beet pulp (SBP) as a substrate. The subculture medium was a salt solution consisting of KH2PO4, CaCl2, etc. Fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°C for 1-2 generations (two days for each generation) and were then used as an inoculum. Exponential cells were inoculated into a medium contain...
