Abstract:
The present invention relates to a composition for controlling plant diseases including an extract of Loeseneriella cambodiana or a Lactam-based compound isolated therefrom as an active component, and a method for controlling plant diseases using the same. The composition for controlling plant diseases according to the present invention can be used for the development of an econ-friendly natural sterilizing agent and the production of organic agricultural products of high added value since the composition is harmless to a human body because the composition is derived from a natural product and shows improved antifungal activity against various plant diseases while not causing environmental contamination.
Abstract:
PURPOSE: A method for producing high quality lactic acids from algal biomass is provided to stably and continuously supply resources using algal biomass and to immediately use the algal biomass after collecting the same because the algal biomass is capable of biochemical/chemical saccharification. CONSTITUTION: A method for producing lactic acids comprises the steps of: preparing one or more kinds of algal biomass selected among Hydrodictyon sp., Chaetomorpha sp., Cladophora sp., Rhizoclonium sp., Enteromorpha sp., and Ulva sp.; putting polysaccharide decomposition enzymes, fermentation stains, or a mixture thereof into a reactor and adding the algal biomass to prepare a reactant; and collecting lactic acids from the reactant. The method further comprises the step of adding a catalyst. [Reference numerals] (AA) Collected Hydrodictyaceae and algal biomass; (BB) Extracted useful material (bioactive substance, lipid, etc); (CC) Extract useful material with water or solvent in advance; (DD) Confrication, dry, sterilization, etc.; (EE) Simultaneous saccharification/fermentation process; (FF) Collected Hydrodictyaceae and algal biomass (fresh body, dried body); (GG) Algal solid after extracting; (HH) Inject biomass one time or more, Catalyst +hydrolase+ lactic acid strain; (II) Ferment for 2-5 days; (JJ) Composite enzyme saccharification; (KK) Chemical hydrolysis; (LL) Low concentration saccharification liquid; (MM) High concentration lactic acid liquid; (NN) Saccharification liquid separation, filtration, concentration (reduce ferment inhibiting material); (OO) Quality sugar concentrate (be used in fermenting and chemical conversion)
Abstract:
PURPOSE: Lactobacillus paracasei LA104 which produces L-lactic acid(LA) is provided to produce a large amount of high purity L-lactic acid by 3-5 g/L of a yeast extract. CONSTITUTION: Lactobacillus paracasei LA104 is provided to produce L-lactic acid. The strain has resistance to stress conditions such as high temperature, high salinity, high lactic acid concentration, high glucose concentration, and low pH concentration. A method for producing L-lactic acid using the strain comprises: a step of injecting the strain, 70-80 g/L of Hydrodictyon reticulum algae, saccharifying enzyme, and 3-5 g/L of a yeast extract to a fermentation device; and a step of fermenting.
