Study on Flocculants of Lactic Acid Fermentation Broth

Abstract:

Flocculation of lactic acid (LA) fermentation broth using chitosan and cationic polyacrylamide (CPAM) as flocculants individually was evaluated. Flocculation effects under different flocculants dosages as well as the loss of the target product LA were investigated. It was found that CPAM was more suitable in flocculation of LA fermentation broth while the optimized dosage of CPAM was 0.2g/L. The results showed that flocculants made little impact on the LA so that it was feasible to treat lactic acid by flocculation.
