Peanut hulls (Arachis hypogaea) are waste byproduct in confectionary and oil extraction industry. Disposal of hulls into soil or burning creates considerable technical and economical problem. Thus, the new uses for waste peanut hulls are explored. Possibility of cultivation of fruit bodies of Pleurotus ostreatus on peanut hulls was investigated in this research. Three problems fell within the scope of the work. The first one was the adaption of the mycelium to growth on peanut hulls. The next one was culturing of the mycelium in a submerged culture for inoculation on solid substrate. The last one was the cultivation of mushroom on solid substrate for production of the fruit bodies. It was found that peanut hulls can be used as a suitable substrate for growth of Pleurotus ostreatus mycelium. Weight of the obtained wet fruit bodies was from 0,148 to 0,200 of the wet weight of solid substrate. This result is close to the one obtained by mushroom producers in traditional cultivation.
