Abstract:
PURPOSE: Juglone is provided to suppress the function of KAPAS(7-keto-8-aminopelargonic acid synthase) which is related to a biotin biosynthesis pathway of microorganisms and plants, significantly control Sicyos angulatus L., and be used as an active ingredient of a safe natural herbicide. CONSTITUTION: A herbicidal composition for controlling Sicyos angulatus L. contains juglone of chemical formula 1 or a pharmaceutically acceptable salt thereof as an active ingredient. Juglone is derived from a black walnut and suppresses KAPAS activity. A method for controlling Sicyos angulatus L. comprises a step of treating Sicyos angulatus L. a seed thereof, or a habitat thereof with the herbicidal composition. The herbicidal composition is used by dipping, spraying or coating.
Abstract:
PURPOSE: A method for preparing hydrolysate highly containing glucose from algae biomass is provided to prevent sharp rise of food price and to enable easy biochemical/chemical saccharification. CONSTITUTION: A method for preparing hydrolysate highly containing glucose comprises: a step of hydrolyzing and chemical-hydrolyzing family Hydrodictyaceae without pretreatment; a step of centrifuging or filtering the hydrolysate to collect supernatant; and a step of concentrating the supernatant by drying at low pressure or membrane permeability evaporation. The hydrolysis catalyst includes an acid catalyst including sulfuric acid, hydrochloric acid, bromic acid, nitric acid, acetic acid, formic acid, phosphoric acid, para-toluene sulfonic acid(PTSA) or solid acid, or an alkaline catalyst including potassium hydroxide, sodium hydroxide, calcium hydroxide, or ammonium solution. [Reference numerals] (AA) Collected family Hydrodictyaceae and algae biomass; (BB) Extracted available substances(physiologically active substances, lipid, etc); (CC) Pre-extraction of available substances using water or solvent; -Pulverizing, drying, sterilizing, etc; (DD) Collected family Hydrodictyaceae and algae biomass(living matter, dried material); -Solid powder of extracted algae; (EE) Saccharification with complex enzyme; Chemical hydrolysis; (FF) Hydrolysate of low concentration; (GG) Hydrolysate isolation, filtration, concentration(reduction of fermentation inhibitors); (HH) Saccharide concentrate of high quality(use in fermentation or chemical conversion)
Abstract:
PURPOSE: A composition for preventing harmful algae containing nano silver is provided to ensure eco-friendly condition to human, animal, and environment. CONSTITUTION: A composition for preventing harmful algae contains nano silver as an active ingredient without nitrogen and phosphorus. The nano silver is silver metal or silver oxide of nano size. The nano silver is contained in 0.01-15 weight% based on total weight. A method for preparing the composition comprises: a step of dissolving silver salt in distilled water; a step of filtering and washing carbon salt or carbon gas; and a step of adding organic/inorganic reductant or persulfated salt and hydroxide to form silver salt in a nano size.
Abstract:
PURPOSE: An antibiotics marker free transformed Festuca sp. plant is provided to improve an effect of preventing weeds and reduce environmental problem. CONSTITUTION: A method for producing an antibiotic marker-free herbicide complex resistant Festuca sp. plant comprises: a step of transforming Agrobacterium with a plant expression vector containing bar gene and CP4-EPSPS gene; a step of co-culturing the transformed Agrobacterium and Festuca sp. embryogenic callus; and a step of selecting transformed shoot from the Festuca sp. embryogenic callus. The Festuca sp. plant is Festuca arundinacea. The plant expression vector is p35S-EPSPS-B vector.
