Problems solved by technology

At present, burdock is mainly sold by direct refrigeration. The deep-processed products mainly include burdock pickles, burdock crisps, burdock tea, burdock wine, and simply crushed burdock powder. It is difficult to meet the needs of the current development of burdock planting and processing industry

example 1

[0019] Example 1 The present invention will be described in further detail below in conjunction with embodiment:

[0020] There are many varieties of Pleurotus eryngii, which are highly adaptable to the medium and the environment, but there are still certain differences in the requirements of specific varieties for the environment and the medium, and there are also great differences in the adaptability of the same variety to the medium. Before adjusting the medium, the strains must first be adapted to the new medium, and the strains adapted to the new medium must be screened first;

[0021] Step 1 strain screening:

[0022] The first step, mycelial adaptability screening: select 10 Pleurotus eryngii mushrooms with complete caps, beautiful shapes, strong growth, and no variegation, and select mushrooms 2 cm below the caps and cut them into 0.5*0.5 Centimeter Ding, inoculated on the potato dextrose agar slant medium under sterile conditions, cultured at 20-27°C for 75 hours, se...

[0031] Step 1 strain screening:

[0032] The first step, mycelial adaptability screening: select 10 Pleurotus eryngii mushrooms with complete caps, beautiful shapes, strong growth, and no variegation, and select mushrooms 2 cm below the caps and cut them into 0.5*0.5 Centimeter Ding, inoculated on potato dextrose agar slant medium under aseptic condition, cultured at 20-22°C for 75 hours, selected the test tubes with strong hyphae growth on the slant medium, eliminated the weak test tubes, and inoculated them on crushed Dried burdock granules, the water content of the granules is 60-62%, cultivated at 22-24°C for 7 to 10 days, and inoculated vigorously growing mycelia on the slant medium of potato dextrose agar, and cultivated at 22-24°C for 75 hour, repeated twice;

[0033] The second step, mycelia mushroom-forming screening: Inoculate the vigorously growing mycelium obtained in the first step of step 1 on the crushed dry burdock granules, the water content of the granules i...

[0039] Step 1 strain screening:

[0040] The first step, mycelial adaptability screening: select 10 Pleurotus eryngii mushrooms with complete caps, beautiful shapes, strong growth, and no variegation, and select mushrooms 2 cm below the caps and cut them into 0.5*0.5 Centimeter Ding, inoculated on potato dextrose agar slant medium under sterile conditions, cultured at 25-27°C for 75 hours, selected the test tubes with strong growth of mycelium on the slant medium, eliminated the test tubes with weak growth, and inoculated on crushed Dried burdock granules, the water content of the granules is 64-65%, cultivated at 25-27°C for 7 to 10 days, and inoculated vigorously growing mycelia on the slant medium of potato dextrose agar, cultivated at 25-27°C for 75 Hour;

[0041] The second step, mycelia mushroom-forming screening: Inoculate the vigorously growing mycelium obtained in the first step of step 1 on the crushed dry burdock granules, the water content of the granules is 64-65...

Abstract

The invention relates to pleurotus eryngii cultivation based on culture mediums of burdock solid fermentation and a method thereof. The method comprises the steps of (1) cultivating adaptability of pleurotus eryngii bacterial strains: (2) smashing the pleurotus eryngii after cleaning, sterilizing and shelling; (3) composing solid fermentation culture mediums; (4) solid fermentation cultivation, including of inoculating activated pleurotus eryngii bacterial strains to solid fermentation culture mediums and then cultivating the bacterial strains under a condition of 16-18 DEG C for 18-20 days. The method has the advantages that burdock is used as a principle raw material, thereby improving the nutrient value of pleurotus eryngii and increasing product characteristics; during the process of mycelium cultivation, silicon windows are used for automatically adjusting gas compositions of growing environment, thereby reducing workload and facilitating to large-scale production.

Description

technical field [0001] The invention relates to a culture medium and a method for burdock solid fermentation fungi, belonging to the field of microbial solid fermentation, in particular to a cultivation method for burdock solid fermentation Pleurotus eryngii. Background technique [0002] Pleurotus eryngii is rich in nutrition and is a high-protein, low-fat nutritious food. my country is a large production country with abundant resources. Traditionally, the medium used for solid fermentation of Pleurotus eryngii is mainly composed of waste such as sawdust and corn cobs. There are also some chemicals that need to be added, and after the fermentation is over, it is very difficult to separate the mycelium from the nutrient-depleted residue of the medium. It is unreasonable if the mycelium is mixed with the residue for application or to extract components or to discard. Therefore research and develop pollution-free, available natural medium, can completely avoid the disadvantage...
