Abstract: To test the antibacterial activity of edible and medicinal fungi, a total of 6 strains of chicken pathogenic bacteria belonging to 3 species including Salmonella sp., Escherichia coli and Staphylococcus aureus, were used as indicator bacteria. The results showed that 12 species 16 strains of edible and medicinal mushrooms with different antibacterial activity were obtained, including Phellinus sp., Sanghuangporus baumii, Inonotus hispidus, Pleurotus citrinopileat, Pleurotus salmoneo-stramineus, Pleurotus ostreatus, Stropharia rugosoannulata, Pleurotus cornucopiae, Hypsizygus marmoreus, Hericium erinaceus, Pleurotus eryngii and Lentinus edodes. Among them, the Stropharia rugosoannulata strain No. 1 and Pleurotus eryngii strain No. 5 exhibited antibacterial activity against all tested pathogenic bacteria. Adding silkworm pupa powder promoted the growth of edible and medicinal mushroom mycelia in varying degrees and further enhanced the antibacterial activity of the strains.
