| titleOfInvention | A method of using cryogenic freezing environment from antibacterial lipopeptid solution desalination |
| abstract | The present invention relates to a kind of methods using cryogenic freezing environment desalination from antibacterial lipopeptid solution.This method comprises the following steps：(1) bacillus amyloliquefaciens fermentation is prepared to the zymotic fluid obtained after antibacterial lipopeptid through filtering, thalline is removed, clarified solution is made；(2) stream plus dilute hydrochloric acid into clarified solution, are stored at room temperature, abandon supernatant, and pulpous state fluid is made；(3) extractant is added into pulpous state fluid, stirs evenly, extract, after centrifugation, through organic membrane microfiltration, filtrate is made；(4) filtrate is crystallized under conditions of 25~10 DEG C, filters removal crystallization through micro-filtration, antibacterial lipopeptid solution is made.Present invention firstly discloses under cryogenic freezing ambient storage environmental condition, inorganic salts in extraction system can fully be precipitated, the organic solution after micro-filtration is precipitated will not occur crystalline polamer again when cryogenic freezing stores again, can solve impurity salt in current antibacterial lipopeptid preparation process and be not easily taken out of problem. |
