En este estudio se evaluó la producción de biomasa, la cinética de crecimiento y la
composición química del micelio de Lentinula edodes obtenido en cultivo sumergido con
suplementación de extractos de madera de vid. Se evaluaron las cepas IE-245 e IE-105 de L.
edodes y tres medios de cultivo base para la producción de biomasa. La combinación con mayor
producción se eligió como control y base para formular dos tratamientos (T1: suplementado con
los cuatro extractos y T2: suplementado con los extractos acuoso y etanólico). La producción de
biomasa no varió significativamente entre los tratamientos (P>0.05), después de 21 días de
cultivo. La máxima producción de biomasa predicha por el modelo logístico se observó en T2
-1 -1 (16.57 g L ) y la mínima en el control (10.78 g L ). Las μ para el control, T1 y T2 fueron 0.052, M
-1 2 0.146 y 0.133 días , respectivamente. El control presentó la R más baja (0.86), mientras que T2
la más alta (0.94). Se encontraron diferencias (P<0.05) entre el control y T1 en contenido de
grasa cruda, así como entre el control y los tratamientos (T1 y T2) en los valores de proteínas y
carbohidratos totales.
