Black fungus cultivation: how to choose black fungus strains?

How to choose black fungus strains? Please describe the method Black fungus in the selection of strains, you can identify the quality of strains through the following methods: 1. Look at the appearance: See if the label of the bottle is consistent with the strain of Auricularia auricula, in case of wrong purchase. Culture time should be within two months, counting from the inoculation date, the age should be 30~40 days, and at the same time, check whether the stopper wall is broken or the tampon falls off. Second, look at hyphae: High purity of white hyphae, thick villi, short dense for high-quality strains. If there are green, yellow, red, green and gray hyphae, they are infected with miscellaneous bacteria and need to be eliminated. Third, look at the ear base: If there is no light black ear base between the bottle wall and the material, it is an excellent strain, and a small amount of ear base is a normal strain. If there are too many, the passage times are too many. Although the ears are early and many after inoculation, they do not grow long and the yield is low. If there is no or only light brown colloid on the bottle wall, it belongs to qualified species; if there is yellow brown liquid, it belongs to aging species and cannot be purchased. IV. Look at the bacteria block: Sawdust spawn surface are long hyphae, no sawdust, dug out to block rather than loose as the best. Pay attention to smell to pull out the cotton plug, smell the fragrance of the strain, it is qualified; if it emits peculiar smell such as wine acid, mildew, etc., it is deteriorated strain and cannot be used. Fungus strains note: If the culture time of the strain is too short or the temperature is too low, the hyphae do not grow into the whole bottle or the hyphae do not grow into the sawdust, they should continue to be cultivated at an appropriate temperature, and then used for inoculation. They should be stored in a clean, dry and dark room. Before inoculation, it is strictly prohibited to pull out the tampon. It is not suitable for the strains inoculated in the opened bottle to stay overnight to prevent contamination by miscellaneous bacteria.
