南极微生物的分离及抗肿瘤活性筛选

Isolation of antarctic microorganisms and screening of antitumor activity

对南极地区(南极大陆、潮间带、南大洋)的海水、海泥、土壤、植物样品进行了微生物分离,并采用海虾生物致死法和流式细胞术对极地微生物发酵产物进行了抗肿瘤活性筛选。从南极样品中共分离极地微生物259株,筛选结果显示,11%的微生物具有显著的抗肿瘤活性,显示出极地微生物在活性物质研究方面具有良好的应用潜力。

There were some samples collected from the Antarctic soil and South Ocean water for isolation of microorganisms and screening of their antitumor bioactivity by lethality bioassay using brine shrimp and a flow cytometric bioassay. There were 259 stains were isolated from the samples, 11% of the Antarctic microorganisms showed strong antitumor activity. This result showed that the Antarctic microorganisms have a good potential in bioactive metabolites researching.
