Figure 2. Validation of the expression of different recombinant enzymes in E. coli through SDS-PAGE analysis.

Figure 2

Recombinant protein expression was induced using 0.5 mM IPTG for a cultivation time of 4 h at 37 °C. Lane M, prestained protein molecular weight marker; lane 1, crude cells extracts from E. coli BL21 star(DE3) harboring pET28a; lane 2, crude cells extracts from strain BL21/pET-mdlC; lane 3, crude cells extracts from strain BL21/pA-adhPyjhG; lane 4, crude cells extracts from strain BL21/pET-mdlC&pA-adhPyjhG; lane 5, crude cells extracts from strain BL21/pA-xylBC; lane 6, crude cells extracts from strain BL21/pE-mdlCxylBC&pA-adhPyjhG. The bands corresponding to the individual proteins were indicated by an arrow.
