| titleOfInvention | Recovery of 5'-inosinic acid by ion exchange resin |
| abstract | According to the present invention, when the supernatant obtained by centrifuging the IMP fermentation broth obtained according to a conventional method is passed through a CI type anion exchange resin, and then eluted, an initial eluent having a IMP concentration of 0.00% (Pre Cut) 1, Initial eluent 2 with an IMP concentration of about 0.15%, Medium eluent with an IMP concentration of about 2 to 2.5% 1 Medium eluent with an IMP concentration of 6.5% or more, Medium eluent 3 with an IMP concentration of about 2% 3, IMP concentration Tail Cut 1 having a concentration of about 0.2 to 0.4% and Terminal Eluent 2 having an IMP concentration of about 0.05% were obtained, and the Middle Eluent 2 was separated and purified according to the following IMP purification step, and the initial Eluent 2 and the final stage Circulating eluent 1, which combines eluent 2, vapor eluent 1, and intermediate eluent 3, adds a certain amount of 35% hydrochloric acid, and circulating eluent 2, which is a final eluent 1, is used as a circulating eluent system. IMP from the ion exchange resin column Provided is an IMP recovery method characterized by dissolution.n n n The method of the present invention increases the IMP concentration by more than 40% compared to the conventional method, the load of the next easy process is significantly reduced, the second use of hydrochloric acid in the eluent is reduced by 15-30%, and the raw materials are saved and third, the utility (Water) Significantly decreases the amount of waste water generated, and reduces the recovery of IMP by more than 99.5% and one time elution time by using the low concentration of IMP eluent as the eluent in the next process instead of discarding it in the waste solution. The effect to make it is obtained. |
