Bazı Mantar Miselyumlarından Yalıtım Malzemesi Üretimi Üzerine Bir Araştırma

Öz

Çalışmada, miselyum bazlı, çevre dostu yalıtım malzemelerinin üretilebilirliğinin araştırılması amaçlanmıştır. Materyal olarak Aydın ilinden toplanan Ganoderma resinaceum (Cilalı reyşi), Schizophyllum commune (Kımuk) ve Agroma Mantar Şirketinden temin edilen Pleurotus ostreatus (İstiridye mantarı) hazır miselleri kullanılmıştır. Deney örneklerinin üretimine uygun kalıplar 3D yazıcı ile hazırlanmış ve mantar üretim çadırı ve iklimlendirme otomasyon sisteminde denemeler gerçekleştirilmiştir. Buğday sapı, mısır ve pamuk sapı gibi tarımsal artıklar miselyum gelişimi için substrat olarak incelenmiştir. Tarımsal artıklar miselyum ile aşılanmış ve 27 °C'de % 60-80 nemde 14 gün inkübasyondan sonra kalıplama yapılmış ve inkübasyona 7 gün daha devam edilmiştir. Kalıptan çıkarılan örnekler 70 °C'de Pasteur fırınında 8 saat kurutulmuştur. Materyal üretildikten sonra, basma, çekme, eğme, ısıl iletkenlik testleri ve FTIR analizi yapılmıştır. Denemeler sonunda substrat olarak buğday sapının, 27 ℃ sıcaklık ve % 60-80 nemde optimum olarak uygunluğu belirlendi. En iyi inokulum miktarını belirlemek için miselyum, malt ekstrak agar içeren petri kabında geliştirildikten sonra, buğday sapı içeren kompost ortamına ½ ve ¼ gibi çeşitli oranlarda miselyumla aşılandı. Üç tip mantar ve üç farklı substrat kullanılarak miselyal büyüme gözlendi. En iyi mantarın Ganoderma resinaceum, en iyi substratın ise buğday sapı olduğu belirlendi.

A Research on the Production of Insulation Materials from some Fungi Mycelia

Öz

It was aimed to investigate the manufacturability of mycelium-based, environmentally friendly insulation materials. Ganoderma resinaceum (Cilalı reyşi),Schizophyllum commune (Kımuk) collected from Aydın Province and Pleurotus ostreatus (İstiridye mantarı) ready-made mycels obtained from Agroma Mantar company were used as materials. Molds suitable to produce test samples were prepared with a 3D printer and trials were carried out in the mushroom production tent and air conditioning automation system. Agricultural residues such as wheat straw, corn stalk and cotton straw were studied as a substrate for mycelium growth. Agricultural residues were inoculated with mycelium and after 14 days of incubation at 27 °C in 60-80% humidity, molding was done and incubation was continued for another 7 days. The samples removed from the mold were dried in a Pasteur oven at 70 °C for 8 hours. The material was produced, compression, tensile, bending, thermal conductivity tests and FTIR analysis were performed. At the end of the trials, wheat straw as substrate, temperature 27 °C humidity 60-80% were determined as optimum. In order to determine the best inoculum amount, mycelium was inoculated into compost medium containing wheat straw in various ratios such as ½ and ¼ of the petri dish after the mycelium was developed in a petri dish containing malt extract agar. Mycelial growth was observed using three types of fungi and three different substrates. It was determined that the best fungus was Ganoderma resinaceum and the best substrate was wheat straw.
