Figure 7

Overexpression of recombinant proteins in L. lactis NZ9000 and NZ9000Δs cells grown in GM17 and GCDM. Cells were induced at OD600≈0.5 with 0.1% volume of nisin A-containing NZ9700 culture supernatant and growth was continued for 2 h. Protein levels were analyzed on immunoblots, using an anti-His tag antibody.
