lactic acid fermentation fine adsorption

With a suitable carrier selective adsorption of lactic acid, can reduce the product inhibition, commonly used adsorbents have Activated carbon, ion-exchange resin. Sodium lactate fermentation with immobilized cells, the activated carbon was added to Cylindrical fluidized bed magnessium lactate, the fermentation broth can be controlled pH. China also launched a lactic acid Fermentation of adsorption. Domestic resin D354 with adsorption capacity, good selectivity, and its PVP resin with the same separation effect. Moldes, etc. The SSF technology and ion exchange resin adsorption Lactic acid fermentation broth is coupled to operation of the system 20h, lactic acid yield was 1.18g (L h).
