Abstract

MÉTODO PARA PRODUZIR CELULASE. A presente invenção refere-se ao fornecimento de um método microbiano para produzir uma proteína de forma econômica e eficiente. Um método para produzir uma celulase, compreendendo cultivar um fungo filamentoso na presença de um substrato de carbono induzível e um substrato de carbono não induzível, em que uma razão R (R = taxa de fornecimento de substrato de carbono não induzível/taxa de fornecimento de substrato de carbono induzível) é 100 ou menos durante um período em que uma taxa de alteração de atividade respiratória do fungo filamentoso é de 0,1 ou mais.METHOD FOR PRODUCING CELLULASE. The present invention relates to the provision of a microbial method to economically and efficiently produce a protein. A method for producing a cellulase, comprising culturing a filamentous fungus in the presence of an inducible carbon substrate and a non-inducible carbon substrate, wherein a ratio R (R = non-inducible carbon substrate supply rate/ inducible carbon substrate) is 100 or less during a period when a rate of change in filamentous fungal respiratory activity is 0.1 or more.
