Purification of lactic acid obtained from a fermentative process of cassava syrup using ion exchange resins Purificación de ácido láctico obtenido a partir de un proceso fermentativo de jarabe de yuca, empleando resinas de intercambio iónico
2012
In this work, the fermentative lactic acid (LA) production and its further separation by ionic exchange resins was evaluated. A Lactobacillus brevis strain was used to perform lab scale experiments under anaerobic conditions, using a low nutritional content media with cassava flour as carbon source (HY1). For a fermentation time of 120h in a 7.5-L bioreactor, the LA concentration was 24.3±0.07g LA/L and productivity 0.20 g/L/h, at pH 6.5 and 38oC.
