神农架林区和自然保护区链霉菌拮抗性的研究(Ⅱ)

Studies on Antagonism of Streptomycetes in Shennogjia Forest and Nature Reserve Region(Ⅱ)

用琼脂移块法对由神农架林区和自然保护区土壤中分离并鉴定了的３６种５７株链霉菌进行拮抗性试验，结果显示３６种５５株链霉菌对细菌或真菌有拮抗性，或对细菌和真菌都有拮抗性，并发现这些链霉菌以较高的百分率拮抗丝状真菌和酵母菌。

The antagonism test by agar block method was performed for fifty_seven strains of thirty_six species of streptomycetes,which were isolated from the soil of Shennongjia Forest and Nature Reserve Region .The results showed that fifty_five strains of thirty-six species of them were antagonistic to either bacteria or fungi,or to both of them.Furthermore,it was indicated that the percentage of antagonism to mold and yeast in this region was high.
