Figure 5From: Combinatorial Sec pathway analysis for improved heterologous protein secretion in Bacillus subtilis: identification of bottlenecks by systematic gene overexpressionCharacterization of engineered and parental strains. B. subtilis 1A751 (pMA5L) (parental strain), 1A237 (pMA5L) (engineered strain), 1A751 (pMA5S) (parental strain) and 1A237 (pMA5S) (engineered strain) were cultivated for 96 h at 37°C in 30 mL SR medium supplemented with 4% xylose (w/v). a Growth of the strains. b Analysis of α-amylase (AmyL and AmyS) activity. c Analysis of productivity. d SDS-PAGE analysis of α-amylase (AmyL and AmyS) at 72 h.Back to article page
