The present work aims to construct a robust recombinantBacillus subtilisto achieve secretory production of alkaline polygalacturonate lyase (PGL). First, 6 signal peptides (amyX, bpr, vpr, yvgO, wapA and nprE) were screened with a semi-rational approach and comparatively investigated their effects on the production of PGL. The signal peptide bpr directed efficient PGL secretory expression and increased PGL titer to 313.7 U mL−1. By optimizing and applying strong promoter P43 and Shine−Dalgarno sequence, higher titer of 446.3 U mL−1PGL was achieved. Finally, the capacity of the recombinantB. subtilisWB43CB was evaluated with a fed-batch strategy in 3 L fermentor. The PGL titer reached 632.6 U mL−1with a productivity of 17.6 U mL−1h−1, which was the highest secretory production of PGL by theB. subtilissystem. The recombinantB. subtilisstrain WB43CB constructed in the present work has great potential in production of alkaline PGL.
