Reuse of Pleurotus ostreatus contaminated material

In the cultivation of Pleurotus ostreatus, the culture materials are often discarded by infectious bacteria after inoculation due to serious environmental pollution, inadequate disinfection of mushroom houses, and aging of bacteria. In order not to waste raw materials, the following two methods can be used to treat contaminated materials:

Pasteurization method: Use 6-7 kg of lime and 400-500 grams of 25% carbendazim per 100 kg of polluting material, and adjust the polluting material to 65% water content. After mixing well, pile the material as high as possible, use a 4 cm thick wooden stick to punch holes vertically to the bottom, punch holes every 30-40 cm, and pull out by rotation. After the beating, the mulch is fermented and turned over when the temperature of the material rises to 60 to 70 ° C. After re-stacking, the stack was turned twice more according to the previous method, and then the heap was cooled down and the viable strains were introduced. The amount of seed used was about 15%.

Atmospheric pressure sterilization method: first dry the contaminated material, and rake it with a rake for 2 to 3 days. According to 100 kg of polluting material, 3 kg of lime, and 300 g of carbendazim, adjust the water content to about 60%, and sterilize under normal pressure for 10-12 hours after bagging, and then stuffy for 12 hours, and then cool to normal temperature Then, insert the appropriate age strain.

After the inoculation, the temperature of the culture room is maintained at 15-20 ° C, and the mycelium can develop normally. The bag can be filled in about 35 days, the mushroom buds appear in 40 days, and the mushrooms can be collected in 4 to 5 days. The development time is 5 to 7 days later than normal, and 2 to 3 tide mushrooms can be collected, and the biological efficiency is 70 to 80%.

Single Use Insufflation Needles

Disposable laparoscopic Veress Needle is a medical device used in laparoscopic surgery to generate pneumoperitoneum, the space created by introducing gas into the abdominal cavity. This space allows surgeons to operate with better visibility and access to internal organs. A Veress needle is inserted through a small incision in the abdomen and is used to inject gas into the abdominal cavity. The disposable version of the Veress needle is designed for single use and is discarded after each procedure to prevent the risk of infection. It is made of high-quality stainless steel and designed to be safe, efficient and easy to use. Disposable laparoscopic Veress needles are commonly used in laparoscopic procedures in hospitals and surgical centers.
