Lignins (L) are complex polymers derived from natural resources that exhibit structures similar to phenol-formaldehyde resins (P-F). They are mainly produced as byproducts of the paper industry. The use of L in partial replacement of (petroleum based and toxic) P during the synthesis of resol type P-F resins generates new "green" macromolecular architectures. This work aims to study the biodegradation of partially modified resols with 10% w/w of sodium lignosulfonate and 10 and 20% w/w of Kraft type L by enzymatic attack of Pseudomonas aeruginosa
