Abstract: The present invention relates to an L-lysine-producing microorganism of the genus Corynebacterium and a method for producing L-lysine using the same.

Abstract: The present disclosure relates to a physically pretreated biomass composition capable of membrane filtration treatment in a biomass solid-liquid separation process, and a method for preparing sugar therefrom. The physically pretreated biomass composition is very useful for the biomass treatment process because MF clogging phenomena do not occur through specific physical pretreatment (attrition milling) of herbaceous biomass and because MF passage speed is improved such that MF can be used in the biomass solid-liquid separation process.

Abstract: The present disclosure relates to strains of Thraustochyrium genus, including a high content of polyunsaturated fatty acids, and a method of producing a biomass using the same. According to the novel CJM01 microalgae of Thraustochyrium genus of the present disclosure, the content of lipids in the biomass and the content of unsaturated fatty acid such as docosahexaenoic acid in the biomass are high, so that the microalgae itself, a biomass produced by the culturing and fermentation of microalgae, a condensate of the biomass, and a dried product of the biomass are very useful as a feed composition.

Abstract: The present disclosure relates to a method for preparing L-cysteine hydrochloride hydrate crystals, and L-cysteine hydrochloride hydrate crystals prepared by the method. Through the method for preparing L-cysteine hydrochloride hydrate crystals of the present disclosure, L-cysteine hydrochloride hydrate crystals can be obtained from a natural L-cysteine fermentation broth with a high recovery rate and/or purity without a chemical reaction or the use of an artificial synthetic compound.

Abstract: The present disclosure relates to a method for preparing a fermented composition, and more specifically, to a method for preparing a fermented composition with improved odor, which comprises preparing grain flour; performing primary fermentation of the grain flour using yeast; performing secondary fermentation of the primary fermented product using a strain of the genus Bacillus; and obtaining the secondary fermented product. The fermented composition of the present disclosure has a high content of a peptide with a low molecular weight, and thus enables the increase of digestibility and absorption rate of proteins during ingestion while also improving the peculiar odor of a fermented product to enhance its palatability.

Abstract: The present invention relates to a Bacillus amyloliquefaciens K2G strain, which is excellent in removal of anti-nutritional factors and in protease activity, and shows excellent antimicrobial activity against pathogens and reduced productivity of viscous substances, a method for producing a fermented soybean meal using the strain, a fermented soybean meal produced therefrom, and a feed composition including the same. The fermented soybean meal prepared by Bacillus amyloliquefaciens K2G strain according to the present invention has few anti-nutritional factors such as trypsin inhibitors, soybean oligosaccharides, and polysaccharides, a high content of crude proteins, and high protein solubility, and also consists of small-sized peptides digestible by livestock due to low-molecularization, thereby being effectively used as a high-quality vegetable protein feed having excellent absorption rate and feed efficiency.

Abstract: The present application relates to a method for preparing L-methionine crystals with an improved bulk density. As the L-methionine crystals prepared according to the method for preparing L-methionine crystals of the present application may have a bulk density of up to 800 g/L, the L-methionine crystals are expected to reduce storage and transport costs of L-methionine powder and improve working conditions due to improved fluidity of the powder.

Abstract: The present disclosure relates to a novel polypeptide having an ability to export an ornithine-based product, and a method for producing an ornithine-based product using the same.
