Binding of the soluble culture medium proteins (A), and the extracted, lignin-bound proteins (B) to lignin-like and anionic polysaccharide polymers. EL, extracellular lignin; Deglycos. EL, extracellular lignin after the glycosyl hydrolase treatment; DHP, dehydrogenation polymer from coniferyl alcohol made with HRP; MWL, milled wood lignin; Ca-PG, Ca-polygalacturonate; Ca-ALG, Ca-alginate. Light gray, unbound fraction; dark gray, bound fraction.
