    • Fermentation of lignocellulosic biomass using ultrasonic pretreatment 

      Schabort, C.J.; Faul, C.; Nagel, M.; Marx, S. (ETA-Florence Renewable Energies, 2014)
      The potential fermentation of the sugars derived from water hyacinth, sweet sorghum bagasse and amaranth using indirect ultrasonic pretreatment, was investigated. The optimum sugar and ethanol yield for the ultrasonic bath ...
    • Production of ethanol from sweetstem sorghum and tropical sugar beet for a rural community 

      Marx, Sanette; Mutepe, Daphne; Brandling, Janine; Van der Gryp, Percy (ETA-Florence Renewable Energies, 2011)
      Rural communities in the North West Province of South Africa are among the poorest in the world with an average income of less than ZAR 8.75 (EU 0.875) per day. The South African government has committed itself to upliftment ...
    • Ultrasonic assisted amaranth stem pretreatment for bio-ethanol production 

      Chiyanzu, Idan; Mditshwa, Amanda; Marx, Sanette (ETA-Florence Renewable Energies, 2015)
      An investigation was undertaken to determine the effect of ultrasound on enzymatic hydrolysis rate and enhanced bioethanol yields. Compositional analysis of the feedstock reveals that amaranth lignocellulose contains 36.35% ...
