Changes in cultural parameters and the production of some extracellular enzymes during growth and autolysis of the white‐rot fugus Pycnoporus cinnabarinus have been studied. At the end of the autolytic period (52 days of incubation) the degree of autolysis was greater than 50%. The laccase activity reached its highest value during the growth period, when the level of the carbon source in the medium was still comparatively high. When the fungus was cultivated in the presence of kraft lignin (Indulin AT) 0.05% (w/v), the activity of laccase was 3 times higher than when grown in the absence of lignin. The presence of lignin did not affect the activities of 1,3‐β‐glucanase, exoxylanase and proteases.
