Effects of deficiency or over-expression of sppA and tepA on the extracellular secretion. a The concentrations of total extracellular proteins of different strains; b SDS-PAGE analysis of the extracellular proteins from different host strains. M protein marker (95, 72, 55, 43, 34 kDa); Lane 1 B. licheniformis BL10; Lane 2 B. licheniformis BL10T; Lane 3 B. licheniformis BL10S; Lane 4 B. licheniformis BL10GT; Lane 5 B. licheniformis BL10GS. 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
