| dc.description.abstract | El uso de residuales de la industria como sustrato es tendencia a nivel mundial, el lactosuero es uno de ellos. El objetivo de la investigación fue encontrar la combinación de temperatura y pH que maximicen la productividad de ácido láctico con el uso de lactosuero yLactobacillus casei. Se evaluaron las variables de temperatura en los valores de (29, 31.1, 37, 42.7 y 45 °C) y pH (4.8, 5, 5.5, 6 y 6.2) para encontrar parámetros óptimos del bioprocesoque maximicen la productividad volumétrica de ácido láctico mediante el uso del Diseño Central Compuesto utilizando el programa Design Expert11.0. Se realizaron trece corridas. Se verificó la validez del modelo cuadrático mediante 3 repeticiones con los parámetros óptimos sugeridos por el programa y se determinó que las condiciones demaximización de la productividad volumétrica son 40.2 °C de temperatura y 5.6 de pH, alcanzando valores de 1.2 gl-1h-1y se confirmó que no existe diferencia significativa (p ≤ 0.05) con los valores brindados por el modelo. Concluyendo que los valores óptimos de temperatura y pH encontrados fueron cercanos a los reportados por otros autores y se demostró que el lactosuero tiene un gran potencial para ser utilizado como sustrato. | es_EC |

| dc.description.abstract-en | The use of industrial waste as a substrate is a worldwide trend, whey is one of them. The objective of the research was to find the combination of temperature and pH that maximizes the productivity of lactic acid with the use of whey and Lactobacillus casei. The temperature variables were evaluated in the values of (29, 31.1, 37, 42.7 and 45 °C) and pH (4.8, 5, 5.5, 6 and 6.2) to find optimal parameters of the bioprocess that maximize the volumetric productivity of lactic acid. by using the Central Composite Design using the Design Expert 11.0 program. Thirteen runs were carried out. The validity of the quadratic model was verified through 3 repetitions with the optimal parameters suggested by the program,and it was determined that the conditions for maximizing volumetric productivity are 40.2 °C of temperature and 5.6 of pH, reaching values of 1.2 g.l-1h-1and it was confirmed that there is no significant difference (p ≤ 0.05) with the values provided by the model. Concluding that the optimal values of temperature and pH found were close to those reported by other authors and it was shown that whey has great potential to be used as a substrate. | es_EC |
