Se evaluó el efecto de distintos niveles de cobre (II) sobre la velocidad específica de crecimiento de Trametes villosa en medio PDA 4% y medio PDA 4% con 25% (v/v) de vinaza. La velocidad específica de crecimiento se obtuvo a partir de los datos de área micelial y de la ecuación para el modelo logístico de crecimiento. Las mejores condiciones para el crecimiento micelial fueron PDA 4% con 25% (v/v) de vinaza y niveles de cobre divalente de 0,5 y 1,0 mM. Estos resultados indican que, de acuerdo con las condiciones de cultivo utilizadas, ambos suplementos favorecen el crecimiento micelial y entregan información esencial para el desarrollo de potenciales procesos de reutilización y valorización de la vinaza. The effect of different levels of copper (II) on the specific growth rate of Trametes villosa was evaluated. The strain was grown on 4% PDA and 4% PDA on a 25% (v/v) vinasse dilution. The specific growth rate was obtained from the mycelial area data which was modeled with the logistic equation. The best growth condition was 4% PDA in a 25% (v/v) vinasse dilution with copper (II) concentrations of 0.5 and 1.0 mM. These results indicate that under the utilized culture conditions, both supplements favor mycelial growth and provide essential information for potential processes of vinasse reuse and valorization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
