摘要: The present invention relates to the field of genetic engineering, particularly to a recombinant expression vector for rapidly screening the high expression strains and a method for rapidly screening high expression strains. In the invention, an exogenous red fluorescent protein and Aspergillus fumigatus cell surface protein localization signal are fused and expressed, and the fusion gene (DsRed-AfMP1) is integrated into the genome of Trichoderma reesei, so as to construct a strain displaying red fuorescent protein on the surface of Trichoderma reesei. By sorting Trichoderma reesei strains with red fluorescent protein on the surface by flow cytometry, genes beneficial to the improvement of cellulase activity can be quickly isolated.

摘要: The present invention relates to a mannanase PMan5A mutant having improved heat resistance, a gene encoding the mutant and application thereof. The mutant is obtained by a substitution of histidine with tyrosine at amino acid residue 93, phenylalanine with tyrosine at amino acid residue 94, leucine with histidine at amino acid residue 356, and/or alanine with proline at amino acid residue 389. The thermal tolerance of the single site mutation mutant H93Y, L356H and A389P are greatly improved over that of the wild-type mannanase PMan5A, and the thermal tolerance of the combination mutants shows the stack effect of the single site mutation, demonstrating the amino acids at the sites of 93, 94, 356, and 389 play an important role for the thermal stability of the mannanase of GH5 family.
