OsmY-Tf0937 secretion using C41(DE3) and BL21(DE3) in 400-mL 2 × TY auto-induction media, at 37 °C and 200 rpm. Cultures were inoculated using 1:100 dilution and samples were collected at 7 h and 24 h of cultivation. (a) SDS-PAGE of spent medium. Lane L: protein marker, Lane 1 and 5: OsmY(WT)-Tfu0937 in BL21(DE3), Lane 2 and 6: OsmY(M3)-Tfu0937 in BL21(DE3), Lane 3 and 7: OsmY(WT)-Tfu0937 in C41(DE3), Lane 4 and 8: OsmY(M3)-Tfu0937 in C41(DE3).
