The activities of target proteins and biomass of different host strains harboring pHY-amyL or pP43SacCNK. a α-Amylase activities and biomass of different host strains harboring pHY-amyL; b nattokinase activities and biomass of different host strains harboring pP43SacCNK. Data are represented as the means of three replicates and bars represent the standard deviations, *P < 0.05; and **P < 0.01 indicate the significance levels between recombinant strains and control strain
