【Abstract】 white rot fungi. Were used in this essay. Six of them were screened with Remazol blue(RB) reactions according to their capability and speed of RB faded. The optimal liquid media for the enzymes producing were defined by the orthogonal trial, and the behavior of their enzyme producing was discussed. According to their ability of enzyme producing and time of enzyme producing peak, 2 strains were screened. The work indicated that the enzyme producing ability of Pleurotus sp2 and Trametes gallic was high and the enzyme producing peak was at early stage of fermentation. It was interesting that the 2 strains degraded lignin preferentially with respect to cellulose, which was very beneficial to biopulping in paper industry.更多还原
