A valuable peroxidase activity from the novel species Nonomuraea gerenzanensis growing on alkali lignin.

ABSTRACT: Degradation of lignin constitutes a key step in processing biomass to become useful monomers but it remains challenging. Compared to fungi, bacteria are much less characterized with respect to their lignin metabolism, although it is reported that many soil bacteria, especially actinomycetes, attack and solubilize lignin. In this work, we screened 43 filamentous actinomycetes by assaying their activity on chemically different substrates including a soluble and semi-degraded lignin derivative (known as alkali lignin or Kraft lignin), and we discovered a novel and valuable peroxidase activity produced by the recently classified actinomycete Nonomuraea gerenzanensis. Compared to known fungal manganese and versatile peroxidases, the stability of N. gerenzanensis peroxidase activit
