| description | The commercial importance of lactic acid (LA) is due to its versatility, especially in the food industry, and for being the precursor of poly-lactic acid, which demands a high-quality LA precursor. The overall LA production process still has some bottlenecks related to costs; thus, alternative substrates such as sugarcane juice may reduce the cost of the fermentation medium and provide a favorable environment for the <i>Lactobacillus pentosus</i> strain, which continues to be explored. In this context, this work presents the process of producing LA from sugarcane juice. The LA purification method is also described using different ion-exchange resins, both in packed columns and in a stirred tank. The fermentation kinetics showed the highest LA production of 113.74 g/L in 96 h, in which a productivity of 1.18 g LA/L∙h was reached. Among the purification techniques, the combined use of Amberlite IR120 and IRA-67 resins under agitation in a stirred tank was the best condition, and resulted in a final LA concentration of 189.11 g/L after 120 min, with 95% LA mass recovery. This result demonstrates a simplified way to use ion-exchange resins safely and in a controlled environment, and with process scale-up viability. |
