  • Engineering cellulolytic ability into bioprocessing organisms 

    La Grange, Daniel C.; Den Haan, Riaan; Van Zyl, Willem H. (Springer-Verlag, 2010-03)
    Lignocellulosic biomass is an abundant renewable feedstock for sustainable production of commodities such as biofuels. The main technological barrier that prevents widespread utilization of this resource for production of ...
  • Engineering of Pichia stipitis for enhanced xylan utilization 

    Den Haan, Riaan (Stellenbosch : Stellenbosch University, 2003-12)
    ENGLISH ABSTRACT: Plant biomass, the most abundant renewable resource in nature, consists of matrices of mainly lignin, cellulose, hemicellulose as well as inorganic components. Xylan, the major hemicellulose component ...
  • Functional expression of cellobiohydrolases in Saccharomyces cerevisiae towards one-step conversion of cellulose to ethanol 

    Den Haan, Riaan; Mcbride, John E.; La Grange, Daniel C.; Lynd, Lee R.; Van Zyl, Willem H. (Elsevier, 2006-09)
    To investigate the possible use of Saccharomyces cerevisiae as a candidate for consolidated bioprocessing (CBP) of cellulose to ethanol, four fungal cellobiohydrolase (CBH) encoding genes (Trichoderma reesei cbh1 and cbh2, ...
  • High level secretion of cellobiohydrolases by Saccharomyces cerevisiae 

    Ilmen, Marja; Den Haan, Riaan; Brevnova, Elena; McBride, John; Wiswall, Erin; Froehlich, Allan; Koivula, Anu; Voutilainen, Sanni P.; Siika-aho, Matti; LaGrange, Daniel C.; Thorngren, Naomi; Ahlgren, Simon; Mellon, Mark; Deleault, Kristen; Rajgarhia, Vineet; Van Zyl, Willem H.; Penttila, Merja (BioMed Central, 2011-09)
    BACKGROUND: The main technological impediment to widespread utilization of lignocellulose for the production of fuels and chemicals is the lack of low-cost technologies to overcome its recalcitrance. Organisms that hydrolyze ...
