Abstract
Technical organosoluble lignins could serve as growth substrate for several fungi of different ecotypes. Certain species of fungi increased the water solubility of the lignin, depending on the glucose concentration in the medium. The solubilization rate was increased also by successive growth of fungi on the lignin. All types of organosoluble lignin induced high activities of extracellular phenoloxidase (E.C.1.14.18.1) in cultures of white-rot fungi. The enzyme activities obtained on organosoluble lignins were higher than on lignosulfonates. Due to the action of phenoloxidases two water-soluble, acid-precipitable lignin polymerizates with different physical properties were formed. The nitrogen and glucose content in the medium plays an important role in the polymerization.
