| titleOfInvention | TRIPTOPHAN DEPARTMENT METHOD |
| abstract | 1. The method of separation of dissolved tryptophan from an aqueous mixture of substances by chromatography with a pseudo-moving layer, which consists in the fact that in the separation part with a column system consisting of at least two series-connected columns filled with an organic polymer suitable for use as an adsorbent and divided into several functional zones, a) a tryptophan-containing mixture of substances and water as a desorbent are continuously fed in separate places of the column system; and b) in the the extract stream enriched with tryptophan is diverted in place and separately from it in another place located along the stream in front of the inlet of the tryptophan-containing mixture of substances, the raffinate stream containing other compounds from the initial mixture of substances is diverted, the extract stream is further processed if necessary, and it is also preferable) columns saturated with undesorbed compounds from a mixture of substances are purified from these compounds. 2. The method according to claim 1, the implementation of which serves preferably desalted water with a temperature in the range from 20 to 98 ° C. The method according to claim 1, the implementation of which uses a mixture of substances containing tryptophan in a concentration of from 0.1 to 39 g / l. The method according to claim 1, in the implementation of which use a mixture of substances with a pH value in the range from 2.5 to 9.5. The method according to one of claims 1 to 4, in which the mixture of substances obtained by fermentation is used, which along with tryptophan also contains phenylalanine and / or tyrosine. The method according to claim 5, in the implementation of which, as a mixture of substances, a mother liquor is used, forming |
