Die Bildung der Phenoloxydase und die Stoffwechselbeeinflussung durch Phenole bei Polystictus versicolor

Mycelial growth and extracellular laccase activity of Fomes annosus in response to cellobiose and sodium ligninsulphonate

“…The hypothesis that laccase is a key enzyme in Fomes annosus and other wood rot fungi seems reasonable since GRABBE et al (1968) found that hgnin diphenols interfere with the energy metabohsm of the fungus. It should be pointed out, however, that the fungus in addition to the extracellular laccase also has an intracellular laccase (HUTTERMANN et al 1977).…”

“…Microscopical (PEEK et al 1972) and chemical (PEEK 1974) investigations of wood infected with Fomes annosus have indicated that delignification is an earlier process than cellulose degradation. The hypothesis that laccase is a key enzyme in Fomes annosus and other wood rot fungi seems reasonable since GRABBE et al (1968) found that hgnin diphenols interfere with the energy metabohsm of the fungus. It should be pointed out, however, that the fungus in addition to the extracellular laccase also has an intracellular laccase (HUTTERMANN et al 1977).…”

Influence of Growth Conditions, Metabolic Inhibitors, and Phenolic Compounds on the ATP Pool in Fomes annosus

“…In the low glucose series, the ATP level decreased rapidly with lack of glucose and beginning autolysis (increase in pH). At 10 g/I glucose the ATP level decreased partially during the late stage of exponential growth but remained at a higher level until the glucose was used up, autolysis began and laccase activity was increased (Grabbe et al 1968). With cellulose or wood as an additional carbon source, the same initial increase in ATP content was reached as with glucose alone.…”

“…CCCP was added to cultures of Fomes annosus. After 2 and 24 h the content of inorganic phosphate in the medium was estimated as also the ATP pool and O2 uptake of the mycelium after 3 h dialysis (Grabbe et al 1968). During the dialysis the ATP pool was lowered.…”

Effect of 2-deoxy-D-glucose on the induction of tyrosinase in Coprinus macrorhizus.

“…It has been reported that cyclic AMP and phosphodiesterase inhibitors induced tyrosinase synthesis in N. crassa (8). A metabolic inhibitor, iodoacetate, was also reported to stimulate tyrosinase production in Polystictus versicolor (9) and in N. crassa (10).…”
