Method of utilizing dendrobium candidum slag for cultivating ganoderma through solid fermentation

The invention relates to the microbial fermentation field and discloses a method of utilizing dendrobium candidum slag for cultivating ganoderma through solid fermentation. The method utilizes dendrobium slag as medium to perform the solid fermentation of the ganoderma and is achieved through the following steps of (1) slant cultivation, (2) seed cultivation and (3) solid fermentation cultivation. The cultured seeds are inoculated into a solid fermentation culture medium at an inoculation size of 10%. The dry materials of the solid fermentation culture medium are composed of 98% of the dendrobium slag, 1.9% of bran and 0.1% of potassium hydrogen phosphate and the weight ratio of the dry materials and water is 1: (1-2.3). The ganoderma is cultivated for 7-20 days at a natural pH value in a temperature condition of 22-32 DEG C. According to the method of utilizing the dendrobium candidum slag for cultivating ganoderma through the solid fermentation, the cellulose in the dendrobium slag is decomposed and utilized by the ganoderma through the fermentation and the biotransformation of the ganoderma to generate high-efficiency bioactive materials such as ganoderma polysaccharide and ganoderma acid, and the deep-processing waste of dendrobium products is converted into high value-added products, so that the all-around comprehensive utilization of dendrobium raw materials is achieved.
