Provided is a method of preparing disodium 5'-guanylate heptahydrate crystals from an aqueous 5′-guanylic acid solution.

Method for preparing disodium 5'-guanylate heptahydrate crystal

Provided is a method of preparing a granular feed additive. When the method of preparing a granular feed additive according to one exemplary embodiment is used, it is possible to prepare a granular feed additive including a high content of basic amino acids while preventing hygroscopicity and agglomeration caused by the basic amino acids. In addition, since the method of preparing a granular feed additive according to one exemplary embodiment may omit a process of using hydrochloric acid, which is generally used to neutralize basic amino acids, it is possible to simplify the process and to solve process problems caused by the use of hydrochloric acid.

Method of preparing granular feed additive

The present application relates to a nucleic acid purification method, specifically to a nucleic acid purification method which includes a first step of crystallizing the nucleic acid using a solution containing a hydrophilic organic solvent; and a second step of drying the crystallized nucleic acid with high-humidity hot air.

The present disclosure relates to a method for preparing L-cysteine crystals, and L-cysteine crystals prepared by the method. Through the method for preparing L-cysteine crystals of the present disclosure, L-cysteine 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.

Method for preparing natural L-cysteine crystals by continuous chromatography

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.

The present disclosure relates to granules comprising an L-amino acid and a method for preparing the same. The method may comprise: (a) preparing a fermentation liquid of L-amino acid; (b) removing moisture from the fermentation liquid of L-amino acid such that the solid content of the fermentation liquid of L-amino acid is in a range of 20% to 90%; (c) forming granulated particles with a moisture content of 0% to 40% by mixing the concentrated fermentation liquid of L-amino acid with a seed; (d) drying the granulated particles formed in Step (c); (e) sieving the granulated particles dried in Step (d); and (f) pulverizing or circulating the particles left in step (e) to be recycled as the seed in step (c).

The present disclosure relates to a preparation method of a methionine-metal chelate, and the methionine-metal chelate, which is prepared by first reacting Ca(OH)and methionine and adding metal chloride salts, can be used as feeds and feed additives.

Methionine-metal chelate and manufacturing method thereof

The present disclosure relates to a preparation method of a methionine-metal chelate, and the methionine-metal chelate, which is prepared by first reacting Ca(OH)and methionine and adding metal nitrate, can be widely used as feeds and feed additives.

The present invention relates to a method for increasing L-methionine productivity and organic acid productivity. More particularly, the present invention relates to a method which involves adding a mixture containing methyl mercaptan and dimethyl sulfide at a appropriate ratio to O-acetyl homoserine or O-succinyl homoserine and to an enzyme having an activity of converting methionine precursor into L-methionine, so as to perform an enzyme reaction, to thereby improve the conversion rate of L-methionine and organic acid from the L-methionine precursor, and thus increasing L-methionine yield as compared to conventional method.
