Excellent purified strains are the fundamental guarantee for the successful cultivation of edible fungi. Here are some methods for identifying the appearance of edible mushroom mothers as follows:
Shiitake mycelium on potato dextrose agar (ie, PDA) medium, hyphae pure white, stout, flocculent or velvet-like, after climbing test tubes have a certain ability to climb the wall, the edge was irregular wave shape. At about 24°C, mycelia can usually grow over a test tube slant 12-15 days. With a special fragrance of mushrooms. ?
Pleurotus ostreatus mycelium on PDA medium, white, thick, thick mycelium, creeping ability of mycelium, can be filled with test tube space. At 25°C, hyphae can generally extend over the bevel of the tube in 6 days. With a special flavor of oyster mushrooms. ?
The mushroom mycelia was on the PDA medium, and the mycelia was grayish white, showing a velvet-like or flat-like appearance with slight wall climbing. After the mycelium ages, brown spots often appear on the surface, and powdery spores and small fruit bodies often appear on slopes. At 23°C, hyphae usually extend over a test tube slant 10-12 days. Mushroom incense is not obvious. ?
Black, hairy agaric mycelium on the PDA medium, the hyphae initially slender and transparent, and later graduated into a white thick secondary hyphae, cotton-like, dense clusters, mycelial front more homogeneous; late easy to produce conidia, The surface layer is covered with a layer of powder. The hyphae do not climb the wall. Plaque plastids appear on the slant after long exposure to light, similar to the ear. At 28-30°C, hyphae secrete different shades of pigments. The fungus is mostly dark brown, and black fungus is mostly amber (its color depth is also related to the length of incubation). The scent is not obvious. ?
Airborne A. bisporus mycelium appeared on PDA medium. Ganoderma lucidum-like plaques appeared 7-9 days after spore germination. The mycelium was robust and fine, and the tip was straight and clear, neat and uniform, and it was fan-shaped and stretched. The aerial mycelium was villous. , easy to form bacteria in the test tube. ?
The mixture of Tremella fuciformis and Hyacinthium typhimurium was cultured in a certain proportion and the mycelium formed was short and dense, and the front end was neat. In the initial stage, the mycelium was velvety, and the growth rate was slow. As the culture time prolonged, a circle of halo that closely adhered to the medium was formed around the hair shaft.
Foot Warmer is also named as Heating Boot, as it looks like a boot in the shape.
It has a fashionable design, hence it is also a good choice as a promotional gift.
In the cold winter, foot warmer is a best choice for keeping warm. When the feet are warm, the entire human body warms up quickly.
It also has a controller with adjustable heat settings, as well as the auto shut off function.
