Comparative experiment on liquid strain substitute cultivation of six strains of Lentinus edodes
In recent years, the production of Lentinus edodes in China has developed rapidly, especially the substitute cultivation of Lentinus edodes. The traditional solid seed production technology of Lentinus edodes can be extended to the production of cultivation bags after the three-stage cultivation of mother seed, original seed and cultivated species. The development of Lentinus edodes is greatly restricted by its great labor intensity, complicated technology, high contamination rate of miscellaneous bacteria, long growth cycle and so on. In this experiment, six liquid strains of Lentinus edodes were cultured and cultivated, in order to provide a theoretical basis for the popularization and application of liquid strains of Lentinus edodes. 1 Materials and methods 1

How to prevent degradation of edible fungi strains
Strain degeneration will lead to slow growth of mycelium, weak resistance to environment, miscellaneous bacteria, etc., fruit body formation period ahead or behind, fruiting tide is not obvious and so on. There are many reasons for strain degeneration, among which impure strain and gene mutation are the main reasons. In addition, high temperature and mixed cultivation of different strains will cause strain degeneration. Measures to prevent strain degeneration include: ensuring pure culture of strains, paying attention not to use strains contaminated by miscellaneous bacteria, not to connect and culture in close proximity; strictly controlling the passage times of strains, reducing mechanical damage,

The strain of Pleurotus ostreatus should be selected correctly in autumn
The quality of strain is the key to the high yield of Pleurotus ostreatus. The high-quality secondary and tertiary strains of Pleurotus ostreatus should have the following characteristics: the hyphae are dense, white, uniform and stout, fluffy, wall-climbing, a small amount of coral-shaped buds appear on the surface of the culture medium, and the appropriate age is 20-25 days. The cross-section mycelium of the strain is obvious and has obvious mushroom flavor. If a large number of fruiting body primordia appear on the surface of the culture medium, it means that the strain has matured and should be used as soon as possible. Before introduction, we must find out the temperature type of the strain, and then according to

Tips for quality identification of edible bacteria
Edible fungi, like the seeds of crops and vegetables, is the internal factor and basis for obtaining high and stable yield. The quality of edible fungi directly affects the yield of edible fungi, and even related to the success or failure of cultivation. Therefore, it is very important to identify and identify the advantages and disadvantages of bacteria. 1. Look at 1. If there are any abnormal spots or patches around or on the surface of the culture material, such as red, yellow, black, green, etc., it means that the strain has been infected by miscellaneous bacteria (except Lentinus edodes, mushrooms and other varieties that produce pigment).

Identification methods of original and cultivated species of Edible Fungi
The mycelium of Lentinus edodes is white, stout, stretched and uniform, with neat edges and fast growth; it develops in the shape of fan feathers in the bottle wall, grows sturdily and secretes soy sauce-colored water droplets. After the mycelium grows full, the amber transparent liquid is often seen within 10-15 days, and it has the unique fragrant smell of Lentinus edodes, no odor and mildew smell. If the mycelium column in the bottle is separated from the bottle wall, it shows that the culture material is caused by too much water; if it is separated, the mycelium column begins to shrink again, and the surface mycelium skin thickens and turns dark brown, indicating that the strain has begun to age and cannot

A STUDY ON HYPOPHILA DISEASE OF EUPHILA EELLUS
In recent years, large-scale intensive culture of European eel has been increasing in China. However, with the expansion of culture scale and the continuous increase of culture density, various problems affecting the survival rate of European eel are increasing day by day, and the outbreak infectious disease of European eel caused by hygrophilic bacteria is one of the outstanding problems. A series of preliminary studies on the physiological and biochemical characteristics, pathogenic factors and pathogenic conditions of hygromonas were carried out in order to provide a powerful theoretical basis for the prevention and control of European eel outbreak infectious diseases and to promote European eel culture to be stronger.

Identification method of edible bacteria
Many edible mushroom growers often reflect that the cultivation failed due to the use of inferior bacteria, but they do not know how to distinguish the advantages and disadvantages of the strains. For this reason, the author specially introduces several simple methods to identify the superior and inferior strains of edible fungi. Pleurotus ostreatus. The mycelium is white, dense, stout, woolly, and has the phenomenon of wall climbing, which is an excellent strain. For example, the bacteria cultured with sawdust, the decomposed sawdust is light yellow, and a small amount of primordia appear, which is an excellent strain. If the hyphae are sparse or fascicled, the cottonseed shell medium is dark red and woody.
