Pleurotus ostreatus surface scraping bacteria can increase production
After harvesting two crops of *Pleurotus ostreatus*, the surface of the growing material often becomes severely dry, compacted, and poorly aerated. This can lead to mycelial aging, which in turn delays mushroom formation, reduces yield, and in some cases, prevents mushrooms from growing at all. To address this issue, a technique called "scraping bacteria" is commonly used, which effectively improves production by revitalizing the mycelium.
The method involves carefully removing the old, senescent layer of bacterial growth from the surface of the substrate. If the material is thick and the bacterial layer is too dense, it should be scraped off in thin layers to expose the underlying mycelium. For slightly hardened surfaces, vertical and horizontal scratches can be made to create small grooves that help expose the mycelium. In bed cultivation, a bamboo broom can be used to sweep back and forth across the surface until the old mycelium is removed, revealing fresh growth underneath. For bag cultivation, the old mycelium on both ends of the bag can be gently scraped away.
This scraping process has a clear stimulatory effect on the formation of primordia, encouraging faster mycelial growth. Typically, new mushroom buds begin to appear 7 to 10 days after the treatment.
It’s important to remove the scraped material from the surface afterward to avoid contamination and the spread of unwanted bacteria. The newly exposed surface should also be leveled for a more uniform mushroom growth. Additionally, avoid misting or watering until the mycelium has fully recovered and begun to grow again. This helps maintain optimal conditions for successful fruiting body development.
