title: Effect of Light Wavelengths and Coherence on Growth, Enzymes Activity, and Melanin Accumulation of Liquid-Cultured Inonotus obliquus (Ach.:Pers.) Pilát.
abstract: To investigate effects of light wavelengths and coherence on growth of liquid-cultured Inonotus obliquus mycelia, melanin accumulation and enzymes activity, culture condition as light of different wavelengths and coherence were studied. Short-term exposure of the vegetative mycelium by low-intensity coherent blue light was optimal for stimulation of growth, melanin synthesis, and increase in extracellular and intracellular activities of tyrosinase and polyphenoloxidase and extracellular catalase. Red coherent light, in the same mode, can effectively be used to stimulate the growth of mycelium and to increase intracellular and extracellular activity of polyphenoloxidase, extracellular catalase and tyrosinase, and intracellular peroxidase. Low-coherent light had less stimulating effect on the biosynthetic activity of I. оbliquus. It should be used in the cultivation directed at the obtaining endomelanin, polyphenoloxidase, and extracellular tyrosinase.
