İSTİRİDYE MANTARININ (Pleurotus ostreatus) YETİŞTİRİLMESİNDE BAZI ENDÜSTRİYEL ATIKLARIN KULLANIM OLANAKLARININ BELİRLENMESİ

The potential of using industrial waste, textile wastes and olive pulp wastes, has been investigated in determining the cultivation possibilities of oyster mushroom (Pleurotus ostreatus). The effects on mycelium growth, harvest time, total time, yield and biological efficiency (BE) were determined in substrates prepared 100 % textile wastes, 100 % olive pulp Düzkale Sözbir, G. / Turkish Journal of Forest Science 5(1) 2021: 187-197 188 wastes and by mixing 75%, 50% and 25% oak sawdust into these wastes (T), olive pulp (Z) and these wastes. While substrates with 100% olive waste and 75%, 50% and 25% olive waste additives showed a slightly acidic effect, substrates with 100% textile wastes and 75%, 50% and 25% textile wastes were slightly basic. It has been determined that slightly acidic substrates shorten the mycelium growth time. The high nitrogen content of the substrates caused low yields. Nevertheless, the highest yield and biological efficiency rate was obtained from oak sawdust substrate, which are 75% added to both industrial waste. It was determined that the highest carbon / nitrogen ratio was obtained as a result of the best yield and biological efficiency value among all substrates. Very good values were obtained in the morphological properties of the mushrooms obtained. As a result of the study, it has been shown that textile wastes (T) and olive pulp wastes (Z) can be used as raw materials in the cultivation of Pleurotus ostreatus mushrooms.
