菌株Tu49代谢产物的分离及抗菌素活性的初步研究

The Isolation of the Strain Tu49 and the Study on the Activity of Its Antibiosis

从吐鲁番葡萄沟、苏公塔、五道林、交角沟等郊区采集的 5 2种土样中筛选到一株能产有抗菌素活性的好气菌Tu49,革兰氏阳性 ,类群为黄色类群。所产生的抗菌素 ,对不同的微生物有明显的抑制作用。最适生长温度为 30℃～ 32℃ ,最适 pH为 6 .8～ 7.5 ,气生菌丝和孢子丝为无色 ,基丝体为黄色 ,产黄色可溶性色素。

We isolated aerial strain Tu 49 from 52 samples of soil in 5 outskirts of Turpan city, its colony was golden and Gram positives(G+).The antibiosis from strain Tu49 inhibited different microorganisms, The optimum growth temperature was 30～32℃ and pH was 6.8～7.5;aerial hypha and spore hypha was colourless, my cellium was yellow. Which can produce soluble figment.
