| Abstract: | Objective] One actinomycete strain from Chinese herb rhizosphere was identified.Method] The bioactivity of the strain was analyzed with multiple-item classification method based on their phenotypic,genetic and phylogenetic characteristics.Result] The fermentation broth of the strain had the activity in the resistance to Staphylococcus aureus and inhibitive activity of interleukin-1β transferase.The morphological,physiological and biochemical,chemotaxonomic and phylogenetic characteristics of the strain complied with these of genus Catenulispora.Conclusion] The strain-I06-01088 belonged to the genus Catenulispora. |
