| 中文摘要: |
| 以3 株食用菌致病木霉为目标菌株，利用热处理过的发酵液研究拮抗细菌B44 对3 株木霉的抑
菌作用。通过对3 株木霉菌丝生长、产孢量以及孢子萌发的研究，结果发现拮抗细菌B44 对3 株木霉均有较
强的抑制作用，随着细菌发酵液浓度的提高，其抑制作用也逐渐增强；在细菌发酵液浓度为40% 时，对3 株木
霉的抑制作用较强，其抑制率分别为79.74%、91.19%、73.37%，而对两株平菇的抑制作用相对较弱，抑制率为
33.80% 和55.46%。因此拮抗细菌B44 具有潜在的生防应用前景。 |

| Taking antagonistic bacterium with significant antagonism against Trichoderma as material，the
antifungal activity of heat-treated liquid fermentation of B44 was analyzed. The results showed that the antagonistic
bacterium B44 had strong inhibitory effect on mycelium growth，sporulation and spore germination of the three strains
of Trichoderma. With the concentration of bacterial fermentation increasing，its inhibition gradually increased. When
the concentration of bacterial fermentation was 40%，the inhibition rate to the three strains of Trichoderma were
79.74%，91.19%，and 73.37% respectively，while the inhibition rate to the two mushrooms were 33.80% and 55.46%
respectively. It was suggested that strain B44 had the potential biological control in mushroom cultivation |
