How to correctly identify buds

P. auriculasis is a non-infectious physiological disorder that occurs commonly in cultivated mushrooms. This condition typically appears when the mycelium transitions from its growth phase to the fruiting body formation stage. One of the most noticeable symptoms is the development of clusters of buds, where only long stalks are formed without any cap. As the stipes elongate, they develop small points at the top. After some time, branches and smaller side branches begin to grow, gradually becoming finer and drooping, creating a shrub-like appearance. This is quite different from the normal upward growth of fruiting bodies, which should form well-structured caps. The primary cause of this disorder is high levels of carbon dioxide (CO₂) and excessive humidity. When the mycelium reaches the stage of fruiting body development, it's crucial to maintain proper ventilation and provide adequate light stimulation. If the environment inside the cultivation bag or bottle becomes too stagnant—due to high CO₂ levels, insufficient oxygen, and lack of light—the mushroom's growth can become abnormal. The result is an elongated stem with no cap, and instead of forming a single fruiting body, the tip may split into multiple branches. To manage this issue, once the primordia appear, growers should ensure good air circulation and provide sufficient light. Maintaining optimal temperature and humidity levels is also essential. If signs of P. auriculasis are observed—such as drooping, bifurcated stems—it’s important to remove the affected mushrooms promptly. By adjusting environmental conditions, the remaining mushrooms can still develop properly. Early intervention and careful monitoring can significantly reduce the impact of this disorder and improve overall yield and quality.

Extraction Kit Magnetics Bead Method

This standard specifies the terms and definitions, classification, technical requirements, test methods, identification, labels and instructions for use, packaging, transportation and storage of nucleic acid extraction kits (magnetic beads method) (hereinafter referred to as "kits"). This standard It is suitable for extracting and purifying human genomic nucleic acid and its fragments from various clinical samples such as serum, plasma, whole blood, cerebrospinal fluid, milk, saliva, urine, sputum, swab, tissue or paraffin-embedded tissue by magnetic bead method , Pathogen nucleic acid kit. Pathogen nucleic acid includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), etc. This standard does not apply to nucleic acid extraction reagents contained in closed systems that cannot extract nucleic acid extraction products for detection.

This kit uses magnetic beads with unique separation function and a unique buffer system to separate and purify high-quality virus from serum, plasma, lymph, cell-free body fluid, cell culture supernatant, urine or various virus preservation solutions DNA/RNA. The uniquely embedded magnetic beads have a strong affinity for nucleic acids under certain conditions, and when the conditions change, the magnetic beads release the adsorbed nucleic acids, which can achieve the purpose of rapid separation and purification of nucleic acids. The whole process is safe and convenient, and the extracted viral DNA/RNA has high yield, high purity, stable and reliable quality, and is especially suitable for automated extraction of high-throughput workstations. The nucleic acid purified by this kit can be applied to various routine operations, including RT-PCR, fluorescence quantitative PCR and other downstream experiments.
