Abstract

La presente invención se refiere a: Un procedimiento de cultivo de microorganismos de origen fúngico, (preferiblemente de los géneros Aspergillus, Penicillium, Rhizopus, Trichoderma, Geotrichum, Fusarium, Mucor y Giberella), sobre un medio de cultivo sólido constitutido de un soporte solido y un líquido conteniendo los nutrientes necesarios para el cultivo, caracterizado por in cluir las siguientes etapas: a) Trituración en partículas del soporte, humedecimiento del mismo con la solución acuosa conteniendo ciertos elementos de la solución nutritiva y esterilización del mismo; b) Impregnación del soporte asi tratado, con la solución nutritiva que contiene el o los substratos carbonados solubles, los agentes de crecimiento y el material inoculado hasta una humedad del conjunto de entre 50 y 85 por ciento c) Fermentación del medio; d) Extracción del 70 por ciento de la fracción acuosa que contiene los elementos biosintetizados (metabolitos secundarios y/o enzimas), mediante la compresión del citado soporte sólido.
