Abstract:
PURPOSE: A new fungal strain, Lecythophora sp. YP363, and a method for producing thermostable cellulase using the same are provided to produce monosaccharides such as glucose and xylose from a cellulose substrate and to reduce enzyme cost. CONSTITUTION: A fungal strain, Lecythophora sp. YP363 (deposit number: KACC93143P), has an excellent enzyme activity and thermal resistance and produces cellulase. A method for preparing cellulase comprises the steps of culturing the strain and isolating cellulase from the culture. The optimal temperature for cellulase is 55 °C. The carbon source in a culture medium is selected among Miscanthus sinensis var. purpurascens, Phragmites communis TRIN., palm fruit peels, barley straw, and rice straw. Cellulase is used for preparing glucose and xylose from a ligneous ingredient.

Abstract:
PURPOSE: A fermentation method for producing ethanol of high concentration using yeast from various kinds of crops is provided to improve ethanol productivity and process. CONSTITUTION: A Saccharomyces cerevisiae KK1 strain(KACC 93077P) is able to produce ethanol of high concentration and high yield. A strain with excellent ethanol productivity is obtained by improving the strain by mutation and selecting. A method for producing ethanol of high purity and high yield comprises a non-streaming way and steaming way. The non-steaming way is performed by mixing grains and water in a ratio of 1:1.3, inoculating Saccharomyces cerevisiae KK1 to the mixture, adding Rhizopus sp. and sacchrifying at 26°C.
Abstract:
The present invention relates to a fungal strain Penicillium oxalicum KL1 (accession no. KACC93151P) and a production method of lignocellulose-degrading enzymes using the same, and more particularly, to a fungal strain Penicillium oxalicum KL1 isolated from soil containing decayed tree fragments and an economical production method of lignocellulose-degrading enzymes culturing the strain. The present invention provides the fungal strain Penicillium oxalicum KL1, which produces several lignocellulose-degrading enzymes having more enhanced enzymatic activity than the known potent enzyme-producing microorganisms, in order to saccharify wooden cellulose to prepare monosaccharides, such as glucose and xylose, and provides an economical production method of lignocellulose-degrading enzymes from low-cost natural fibrous materials. Therefore, the costs of enzymes necessary for producing industrially useful monosaccharides, such as glucose and xylose, from lignocelluloses can be reduced.
Abstract:
PURPOSE: A fermentation method for preparing fermented fucoidan as a cosmetic material is provided to enhance functionality such as collagen synthesis, whitening, and MMP(matrix metalloproteinase) suppression. CONSTITUTION: A method for preparing fermented fucoidan with enhanced anti-aging functionality, collagen synthesis, whitening, and MMP suppression comprises a step of fermenting with microorganisms such as Bacillus subtilis, Lactobacillus plantarum, and Saccharomyces cerevisiae. The fermented fucoidan is used as a raw material of a cosmetic product, a food product, and a pharmaceutical product. The fucoidan is polymer fucoidan which is isolated from kelp with a purity of 80%.
