Figure 2.

A recombinant benchmark strain and the recombinant Δoch1 strain were cultivated under inducing conditions in the presence or absence of a protease inhibitor cocktail in shake flasks at 25°C for 96 hours. (A) OD₆₀₀ values over induction time; (B) total extracellular protein concentration in mg·mL⁻¹ over induction time. Dark gray solid line with squares, benchmark strain without protease inhibitor; dark gray dashed line with dots, benchmark strain with protease inhibitor; black solid line with squares, Δoch1 strain without protease inhibitor; black dashed line with squares, Δoch1 strain with protease inhibitor.
