Description
Abstract
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.
Abstract: Evaluation of the mycelial growth of Trametes villosa (Sw.) Kreisel in media supplemented with copper (II) and sugarcane vinasse 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.
