Crop commodity is usually done on the sawdust of deciduous trees. Agrocybe aegerita is an edible mushroom characterized by high content in protein, easily digested by human gastrointestinal. This experiment was set to investigate mycelial growth and yield of two strains of A. aegerita on different substrates. In the laboratory experiment, mycelial growth on 8 agar media (PDA, Standard, wheat, MA, CYM, potato-carrot based, 2 sawdust extract: alder, beech and birch (1:1)) and 5 sawdust substrates (birch, beech, oak, maple, alder) was investigated. Petri dishes (O 9 cm) for agar media and biological tubes (18 cm long and O 2.5 cm) for sawdust substrates were used. In the cultivation studies, two kinds of sawdust substrates were used: birch, beech and mixture of beech and alder (1:1). Each of the sawdust was moisturized up to 70%. After sterilization the substrate was inoculated with mycelium (on grain) of the investigated strains and incubated at 25°C. Later, when mycelium has completely overgrown the substrate the temperature was decreased to 1517°C to initiate primordia formation. The cultivation was enlightened 10 h/d with Day-Light lamps (500 lx). One crop was harvested after 5 weeks. The carpophores of black poplar mushrooms were picked up in clusters. The laboratory experiment showed no statistically important difference between the mycelial growths of the investigated strains. The best growing agar media were PDA, MEA and wheat, both strains showed slowest mycelium growth on CYM. The linear mycelial growth was the best on the beech and birch sawdust. The two investigated strains differed significantly within the yield on the beech and birch sawdust. The best substrate for cultivation of A. aegerita was birch sawdust. The weight of single carpophores as well as the weight of single cap, as the edible part, was measured. Both investigated strains were characterized by big and heavy carpophores.Read More
