It is not difficult to obtain a good strain, but it is difficult to keep a good character of a strain for a long time. The bacterium production technology introduced here is, in a certain sense, focused on the excellent traits of preserved strains, starting from general production practices, and measures taken to ensure that edible fungi can obtain high quality and high yields.
The majority of edible fungi are basidiomycetes, and a few are Ascomycetes. The reproduction of edible fungi has been described in detail. For strain production needs, here is a brief introduction to the knowledge of the life history of agarics, fungus, and white fungus, so that the strains have a theoretical basis for making.
(1) The agaric agarics are the main edible fungi that are cultivated now, and the agaricus belongs to the basidiomycete class, which has a fruit carrier. The sub-solid layer grows on the surface of the bacteria folds, and the burdens in the sub-solid layer are closely lined up, the burden is rod-shaped, no separation, the top four urine, and each small hard stand grows as a spore. Some species in the sub-solid layer have a few types of larger cells, called septa (cystic bodies), which are generally longer and thicker than the burden, beyond the sub-solid layer. The base of the sub-solid layer is pseudo-thin-walled tissue, called sub-solid layer. In the central part of the pleats, the mycelium is loosely arranged and called the mycelium.
After the spores matured, they fell off from the small stalks and germinated into a single mycelium. Two mononuclear mycelium cells are joined to form a double-core mycelium. For different combinations, two kinds of compatible "+" and "-" hyphae must be available for joining.
Binary mycelial cells also have a lock-like association when they divide. First, on the wall between the two nucleus, a small bulge appears, which resembles a very short branch. The branch is bent downwards, and its apex is fused with another part of the mother cell. First, one nucleus of the cell moves into the neurite. Then the two nucleuses respectively undergo mitosis, forming four nucleus, two in the upper part of the cell and one in the lower part. One is in a short branch, at which point the cell produces two membranes that divide the cell in two. One of the nuclei in the bulge then also moves into the latter cell, making up two binucleated cells. The interlocking combination of the dinuclear hyphae is only present in Basidiomycetes except for a few of the Ascomycetes. However, in the basidiomycetes class, such as red mushrooms, lactarius, honey fungus and the like, there is no lock-like joint phenomenon.
The double-nuclear hyphae continue to divide, grow and develop. Under suitable conditions, buds can be produced to form fruit bodies and complete one generation.
(2) The fungus, tremella fungus, and white fungus may be called ear types. The shape of the fruit body is ear, and the whole is composed of glial hyphae. The top surface of the ear piece is a sub-solid layer formed by tightly arranging the burden and side threads. The solid layers of black fungus and fungus are only born on the lower surface, and the upper surface is covered with fluff. One to several layers of stratum, auricularia, tremella, and binuclear mycelium in the middle of the ear are formed by a lock-like combination method, and form a fruit body primordium on the surface of the matrix, and continuously develop into a fruit body.
