En este trabajo se estudiaron los patrones de producción de ácido cítrico por Aspergillus niger 10 en fermentación en estado sólido (FES) utilizando espuma de poliuretano (PUF) como soporte. Los resultados obtenidos demuestran que la acumulación de ácido cítrico en FES no depende de la presencia del glicerol producido en...
Citric acid is industrially produced by liquid-state fermentation using fungi of the genus Aspergillus; however, this process heavily relies on the composition of the culture medium. On the other hand, citric acid production by solid-state fermentation is more robust in physiological and nutritional terms, favoring the growth and enabling the...
In this study hydroxycinnamic acids were biotransformed. These acids are present in mexican agricultural by-products such as coffee pulp. In order to fulfill this study, moulds from the Universidad Autónoma Metropolitana Iztapalapa (UAMI) and from the Institut de Recherche pour le Développement (IRD) were used. These strains were isolated from...
