Abstract
1. Способ ионообменного выделения лизина из культуральной жидкости, включающий отделение биомассы путем микрофильтрации, осветление нативного раствора, сорбцию лизина на сульфостирольном катионите, элюцию лизина раствором щелочи, кристаллизацию лизина, центрифугирование кристаллов и сушку, отличающийся тем, что, с целью 100% заполнения лизином полной обменной емкости катионита перед сорбцией из нативного раствора полностью удаляют конкурирующие с лизином посторонние ионы путем обессоливания, а чистый раствор, содержащий лизин в солевой форме, пропускают через колонну с анионитом в ОН--форме, получая нейтральный цвиттер-ион лизина, сорбирующийся на H+-форме катиона по механизму хемосорбции. ! 2. Способ по п.1, отличающийся тем, что для обессоливания нативного раствора используют 5 ионообменных колонн с анионитом в ОН--форме и 5 колонн с сильносшитым сульфостерольным катионитов в Н+-форме, пары которых: анионит-катионит соединены последовательно, причем отношение высоты к диаметру каждой колонны составляет 0,8, а скорость пропускаемого через систему раствора составляет 2-2,5 объема на объем всех колонн в системе. ! 3. Способ по п.1, отличающийся тем, что, с целью получения максимальной концентрации элюата для элюции используют 3-5 н (предпочтительнее 4 н) раствор NaOH, который пропускают через колонну со скоростью 0,2-0,3 объема на объем катионита в колонне. ! 4. Способ по п.1, отличающийся тем, что, с целью исключения процесса выпарки элюата перед кристаллизацией процесс нейтрализации лизина до рН 4,5-5,5 осуществляют одновременно с процессом кристаллизации, подавая с помощью барботажа в элюат газообразный хлористый водород при т1. The method of ion-exchange isolation of lysine from the culture fluid, including the separation of biomass by microfiltration, clarification of the native solution, sorption of lysine on sulfostyrene cation exchange resin, elution of lysine with an alkali solution, crystallization of lysine, centrifugation of crystals and drying, characterized in that, with the aim of 100% filling with lysine Before sorption of the full exchange capacity of cation exchanger, foreign ions competing with lysine are completely removed from the native solution by desalination, and a pure solution containing lysine in saline nth form is passed through a column with anion exchange resin in the OH - form, obtaining a neutral zwitterionic lysine ion adsorbed on the H + form of the cation by the chemisorption mechanism. ! 2. The method according to claim 1, characterized in that 5 ion-exchange columns with anion exchange resin in OH-form and 5 columns with strongly cross-linked sulfosterolone cation exchangers in the H + form, the pairs of which: anion exchange resin-cation exchange resin are connected in series, are used to desalinate the native solution the ratio of height to diameter of each column is 0.8, and the speed of the solution passed through the system is 2-2.5 volumes per volume of all columns in the system. ! 3. The method according to claim 1, characterized in that, in order to obtain the maximum concentration of the eluate for elution, 3-5 n (preferably 4 n) NaOH solution is used, which is passed through the column at a rate of 0.2-0.3 volume per volume cation exchanger in the column. ! 4. The method according to claim 1, characterized in that, in order to exclude the process of evaporation of the eluate before crystallization, the process of neutralizing lysine to a pH of 4.5-5.5 is carried out simultaneously with the crystallization process, by supplying gaseous hydrogen chloride by bubbling into the eluate at t
