【摘要】 目的对小连翘(Hyperioums Sampsonii Hance.)内生放线菌YBL-02菌株的进行分类、发酵及产物的提取和初步鉴定。方法根据形态学,培养特征等初步鉴定YBL-02菌株,并采用薄层色谱和红外光谱等对YBL-02发酵产物进行分离和初步鉴定。结果根据菌株的形态学,培养特征等初步将YBL-02菌株归属为链霉菌属。对YBL-02菌株发酵产物进行分离纯化,最后得到具有活性的片状白色结晶体,测其熔点为117～119℃。对该物质进行红外光谱分析后可得出为一种酰胺类化合物。结论YBL-02菌株是一种链霉菌,其发酵产物中活性成分为一种酰胺类化合物。更多还原

【Abstract】 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.更多还原
