Separation and Artificial Domestication of Wild Koumo Mushroom ( Tricholoma gambosum )
A study on carbon and nitrogen sources nutrition was inaugurated in order to provide the basis for artificial domestication cultivation of koumo mushroom ( Tricholoma gambosum). The results showed that sucrose and beef extract were the respectively optimal carbon and nitrogen source. The strain in the PSA medium grew fast and the hyphae became more densely after tube-transferring purification and domestication cultivation in different media. However, the hyphae were not stout enough as compared with mycelium of table mushroom (Agaricus bisporus) no matter on grains of wheat or done material, therefore, it still lakes time and has distance to produce mushroom. The domestication of koumo mushroom is very difficult, wishing to obtain a substantial breakthrough is to master its growth law and ecological habits. The key factor that affects the hyphae and sporogonia of Mongolian koumo mushroom to grow normally is temperature. As a result of a long-term adaptation to cryo-ecological environment, property fumbling for temperature is the key technique of the domestication cultivation. The koumo mushroom has a strict nutritional requirement, therefore , the screening of media is of vital importance.
