Taxonomy, Fermentation and Products Characterization of Actinomycete Strain YBL-02 from Hyperioums Sampsonii Hance

OBJECTIVE Taxonomy of strain YBL-02 isolated from the roots of Hyperioums Sampsonii Hance was studied. And the fermentative products of strain YBL-02 were collected and identified primarily.METHODS The characteristics of substrate mycelium , aerial mycelium and growth on the different culture media were used to identify the strain YBL-02. Some techniques, such as thin-layer chromatography, infra-red spectrum, were used to collected and identified the products of fermentation of strain YBL-02.RESULTS Strain YBL-02 was an actinomycete by the primary taxonomic study. The fermentative products of strain YBL-02 were a kind of lamellar white crystalline form. The melting point of the crystalline form was 117-119℃.It was identified as a kind of chemical compound containing amide groups. CONCLUSION Strain YBL-02 is an actinomycete，and its fermentative products were a kind of chemical compounds containing amide groups.
