| 摘 要： | 为进一步更加科学地开发利用九香虫抑菌物质,采用直接离心法、匀浆法和浸提法3种方式提取九香虫血淋巴,并分别检测每一种提取法所得上清液、下层液体和沉淀物质的抑菌活性,并进行比较分析.结果表明,血淋巴原血对10种试验菌的抑菌圈直径均大于0.7 cm,对革兰氏阳性菌的抑菌活性(MIC=16)强于革兰氏阴性菌(MIC=8).说明...

| Abstract: | The antimicrobial activity of supernatant,subnatant and precipitation of haemolymph,which was isolated by 3 different methods(centrifugation,homogenate and lixiviation) from Aspongopus chinesis,were measured and comparatively analyzed to scientifically develop and utilize antibiotic substances from Aspongopus chinesis in further.The results showed that the inhibition zone diameters of the supernatant were all over 0.7cm,and the antimicrobial activities of the supernatants against gram-positive bacteria(MIC=... |
