| 摘 要： | 本研究采用MTT法对海洋放线菌、细菌、霉菌及极地和大洋细菌进行细胞毒活性物质的筛选，结果有10%放线菌有一株极地细菌具有细胞毒活性。此外利用DNA修复特性在E.coli343/591和E.coli343/636之间的差异性，对前面筛得的菌侏进行DNA损伤的筛选，结果得到两株活动性菌株。采用荧光染色观察得到3株具有诱导肿瘤细胞凋亡的菌株，这些具抗肿瘤活性的菌株可供进一步研究。

| Abstract: | A screening model of MTT was used to identify antitumor active material from marine actinomycetes ,bacterials,molds and extreme bacterials. The results showed about 10 percents of actinomycetes and one polar bacterial strain have cell toxicity. Further more, according to the DNA repair test vitality different between E.coli 343/591 and E.coli 343/636, two positive strains were identified. By fluorescence dyeing, we observed that three strains had the ability to induce cell apoptosis. These strains can be further researched for antitumor drug study. |
