  • METHOD FOR HYDROLYTIC PRE-TREATMENT OF LIGNOCELLULOSIC AND PERENNIAL HERBACEOUS BIOMASS AND FOR PRODUCTION OF SACCHARIDE AND BIOETHANOL FROM THE PRE-TREATED BIOMASS
    Publication number: 20130052697
    Abstract: Disclosed is a method for the hydrolytic pre-treatment of lignocellulosic and perennial herbaceous biomass. By the method, a material suitable for use in the production of saccharides and biofuels can be prepared from lignocellulosic biomass such as pine wood and oak tree wood and perennial herbaceous biomass such as flame grasses and reeds. It is characterized by wet-triturating, microwaving and popping processes. Also, a method is provided for the production of saccharides and bioethanol from the pre-treated biomass.

  • PREPROCESSING METHOD OF HYDROLYZING LIGNOCELLULOSIC BIOMASS AND METHODS OF MANUFACTURING SUGAR COMPOUND AND BIOETHANOL FROM BIOMASS PROCESSED USING THE PREPROCESSING METHOD
    Publication number: 20120301928
    Abstract: The present invention relates to a method of pretreating lignocellulosic biomass prior to hydrolysis, and, more particularly, to a method of pretreating lignocellulosic biomass prior to hydrolysis using wet milling in combination with popping, a method of manufacturing a sugar compound from the biomass pretreated using the method, and a method of manufacturing bioethanol from the biomass pretreated using the method. According to the present invention, energy consumption can be reduced, lignocellulosic biomass can be easily pretreated in an environment-friendly manner without treating chemicals, and the efficiency of hydrolyzing lignocellulosic biomass can be remarkably improved.

  • Transgenic plants expressing cellulase for autohydrolysis of cellulose components and methods for production of soluble sugar
    Patent number: 7786345
    Abstract: The present invention relates to transgenic plants for producing cellulose by a mechanism of autohydrolysis and a method producing soluble sugars using them, more particularly to transgenic plants transformed with recombinant cDNA coding cellulase, cellulose binding domain and chloroplast targeting peptide and a method producing soluble sugars using them. Transgenic plants and a method producing soluble sugars using them would be a highly cost-effective system for the production of soluble sugars on a large scale.
