Growth patterns of nisin inducible L. plantarum NZ7100 strains on MRS supplemented with 10 μg/μl of chloramphenicol with or without diamide after nisin induction. The strain NZ7601 carrying the over expression of gene trxB1 was grown in MRS broth (white circles) and in MRS with 5 mM diamide (black circles) and the wild type strain NZ7606 was grown in MRS broth (white triangles) and in MRS with 5 mM diamide (black triangles). The growth was monitored by turbidity measurements at 600 nm.
