Maximizing total sugar recovery from pretreatment-hydrolysis of sweet sorghum bagasse through cultivar selection and process optimization

Autor: Oscar K. K. Bedzo, Danie Diedericks, Paul McIntosh, Daneal C. S. Rorke, Eugene van Rensburg, Johann Gorgens

The nature of a sweet sorghum cultivar influences the recovery of sugars from the bagasse during pretreatment. The sugars recovered are used in applications for conversion to high-value products such as alcohols, organic acids, and other fuels and ch

Optimisation of Pretreatment Catalyst, Enzyme Cocktail and Solid Loading for Improved Ethanol Production from Sweet Sorghum Bagasse

Autor: Casper B. Dreyer, Eugéne van Rensburg, Johann F. Görgens, Oscar K. K. Bedzo

Publikováno v: BioEnergy Research. 15:1083-1095

Sweet sorghum bagasse displays many characteristics rendering it a promising substrate for lignocellulosic ethanol production. In this study, the steam pretreatment catalyst, enzymatic hydrolysis and the substrate loading for the fermentation were in

The Microbial Devulcanisation of Waste Ground Tyre Rubber Using At. ferrooxidans DSMZ 14,882 and an Unclassified Sulphur-Oxidising Consortium

Autor: Oscar K. K. Bedzo, Eugéne van Rensburg, Kathryn Mary Allan, Johann F. Görgens

Publikováno v: Waste and Biomass Valorization. 12:6659-6670

Sol fraction, a measure of the free polymers removed from a ground tyre rubber (GTR) by organic solvent, and crosslink density, a measure of the number of sulphur crosslinks in the GTR, are necessary to determine whether a microbial activity causes b

Techno‐economic analysis of the valorization of brewers spent grains: production of xylitol and xylo‐oligosaccharides

Autor: Lukas J. Swart, Oscar K. K. Bedzo, Abdul M. Petersen, Johann F. Görgens

Publikováno v: Journal of Chemical Technology & Biotechnology. 96:1632-1644

BACKGROUND: Brewers spent grains (BSG) represents ≤85% of a brewery's solid waste and common disposal to landfill is increasingly more difficult. Yet BSG is a food‐grade by‐product with potential economic valorization that can significantly imp

Intensification of Xylo-oligosaccharides Production by Hydrothermal Treatment of Brewer’s Spent Grains: The Use of Extremely Low Acid Catalyst for Reduction of Degradation Products Associated with High Solid Loading

Autor: Johann F. Görgens, Lukas J. Swart, Oscar K. K. Bedzo, Eugéne van Rensburg

Publikováno v: Applied Biochemistry and Biotechnology. 193:1979-2003

Brewers’ spent grains (BSG) make up to 85% of a brewery’s solid waste, and is either sent to landfill or sold as cheap animal feed supplement. Xylo-oligosaccharides (XOS) obtained from BSG are antioxidants and prebiotics that can be used in food

Pilot-scale xylooligosaccharide production through steam explosion of screw press–dried brewers’ spent grains

Autor: Johann F. Görgens, Eugéne van Rensburg, Oscar K. K. Bedzo, Lukas J. Swart

Publikováno v: Biomass Conversion and Biorefinery. 12:1295-1309

Brewers’ spent grains (BSGs) represent the largest quantity of solid waste from brewing, while xylooligosaccharides (XOS) produced from BSG show promising applications in food, beverage and health products. Production of XOS from a Weiss and malt B

Investigating the effect of different inulin-rich substrate preparations from Jerusalem artichoke (Helianthus tuberosus L.) tubers on efficient inulooligosaccharides production

Autor: Johann F. Görgens, Oscar K. K. Bedzo, Eugéne van Rensburg

Publikováno v: Preparative Biochemistry & Biotechnology. 51:440-449

Commercial production of inulooligosaccharides (IOS) relies largely on chicory roots. However, Jerusalem artichoke (JA) tubers provide a suitable alternative due to their high inulin content and lo...
