Last Updated: 2024/11/06, Excuse me, why does the late growth of Pleurotus ostreatus have some small white bumps? There are many black varieties, but gray and white varieties rarely occur. The same planting methods and culture materials. Why did this happen? How to prevent and cure such miscellaneous bacteria? All aspects of Pleurotus ostreatus production may be contaminated by miscellaneous bacteria and must be prevented in time. The common miscellaneous bacteria are mainly as follows: (1) most of the bacteria occur on the slope of the mother species, and the harm of the original species and cultivated species is relatively mild. Bacterial contamination is characterized by rapid reproduction, usually 10 to 24 hours after inoculation.

All aspects of Pleurotus ostreatus production may be contaminated by miscellaneous bacteria and must be prevented in time. The main kinds of common miscellaneous bacteria are as follows:

The main results are as follows: (1) most of the bacteria occur on the slope of the mother species, and the harm of the original species and cultivated species is relatively mild. Bacterial contamination is characterized by rapid reproduction, which can be shown in 10 to 24 hours after inoculation. Prevention and control methods: first, vaccination tools must be wiped with alcohol and sterilized with flame. Second, the sterilization of culture medium should be carried out in accordance with the regulations.

(2) Penicillium and Trichoderma damage are common in original and cultivated species. Soon after invasion, it germinated and grew into hyphae, covering the surface of the culture medium. Trichoderma occurs in the fruiting body formation stage. When these two kinds of miscellaneous bacteria appear, they should be dug up in time.

(3) Alternaria is most likely to produce Alternaria and produce a large number of orange-red powdery spores in the summer high temperature season. Strains contaminated by Alternaria should be eliminated in time; bottles should be thoroughly cleaned and soaked in 0.05% potassium permanganate water, or steamed and sterilized before use.
