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)

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.
Abstract:
PURPOSE: A composition used for marine algae pretreatment for a process of preparing glucose from marine algae is provided to enable relative saccharification and to prepare a large amount of saccharides of glucose from the marine algae. CONSTITUTION: A solution composition for pretreatment for a process of preparing glucose from marine algae contains 0.1-10 wt% of hydrolysate, 0.1-10 wt% of hydrogen peroxide, 0.1-10 wt% of silicate, and 0.001-1.0 wt% of sulphate. The weight ratio of the hydrolysate and hydrogen peroxide is 1:5-5:1. The hydrolysate includes sodium hydroxide, potassium hydroxide, calcium hydroxide, or ammonium hydroxide. The silicate is sodium silicate, aluminum siliate, boron silicate. A method for preparing glucose from marine algae comprises: a step of putting hydrolysate, hydrogen peroxide, silicate, and sulphate into water to prepare a solution for pretreatment; a step of pre-treating the marine algae with the solution; and a step of adding saccharifying enzyme to marine algae.
