This is the first report using lactose as inducer of recombinant peroxidase which was purified by IMAC in a single step.

Peroxidase isoform (PodC) was heterologously expressed using Escherichia coli Rosetta 2 in a fermenter.

PodC from inclusion bodies was refolded under oxidative conditions and purified with a yield of 36 mg L^-1 of culture.
