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).

Granules comprising L-amino acid and method for preparing the same

Provided is a method for refining quinolinic acid, including the steps of: preparing a fermentation solution including at least one of quinolinic acid and a salt thereof; removing microbial cells from the fermentation solution; preparing an acidic composition containing at least one of quinolinic acid and a salt thereof at a saturation concentration or more by adding an acid to the fermentation solution; and recovering a crystal of least one of quinolinic acid and a salt thereof from the acidic composition.

A process for the production of animal feed additives from fermentation broth containing L-lysine is disclosed. The process does not require filtering of biomass in order to remove the biomass and produces granulated lysine of controllable lysine content with a high bulk density, low viscosity, and a low hygroscopic property which does not require the addition of an anti-absorptive substance. In this process, a lysine fermentation broth produced after slant culture, flask culture, seed process, and cultivation process is concentrated to a solid content of about 44&#x2dc;52%. A product with low hygroscopicity, high bulk density, and the intended amount of contents is produced after being mixed with substances for controlling the amount of contents and granulated by coating the surface of the seeds. This process enables a production of animal feed additives having a lysine-HCl content of at least 65%, a water content of at most 3%, and a bulk density of 670&#xb1;50 kg/m.

Animal feed additives based on fermentation broth and production process thereof by granulation

Provided are a method for preparing a granular animal feed additive and the granular animal feed additive prepared by the method. The method includes: filtering, with a membrane filter, a fermentation broth obtained from a lysine producing microorganism cultured in a lysine producing condition to obtain a lysine-containing filtrate and a microorganism-containing sludge; drying the filtrate to obtain a concentrate with a total solid content of 48 to 52 wt %; granule-drying the concentrate at a temperature of 50&#xb0; C. to 60&#xb0; C. to obtain granules; and coating the granules with a coating agent containing one or more selected from the group consisting of the sludge, a diluent or a free lysine as a lysine content adjustor, and a moisture prevention agent, to obtain lysine granules having the following properties:
