海南文昌清澜港红树林真菌抗B16肿瘤细胞活性菌株的筛选

Screening of Cytotoxic Activity Against B16 Tumor Cell of Mangrove Fungi Isolate from Qinglan Harbor in Hainan

从海南文昌清澜港红树林采集78份植物组织和土壤样品。对样品进行真菌分离,共分离得到真菌608株,采用目测法对其体外抗肿瘤细胞活性进行检测,发现81株红树林真菌对小鼠黑色素瘤B16细胞有不同程度的抑制作用,占总分离菌株的13.32%。结果表明,从红树植物杯萼海桑中分离得到真菌菌株的数量最多,而从红树植物银叶树分离得到的抗肿瘤细胞活性菌株数量最多。

Six hundred and eight fungi strains were isolated from seventy-eight samples of mangrove plants and soil that collected from Qinglan harbor. Cyctotoxic activity was detected by observing the growth inhibition or killing of the tumor cells under microscope. The result showed that 81 strains （about 13.32% of the total strains isolated） displayed cytotoxic activity against B 16 tumor cell. The most fungi strains were isolated from mangrove plant Sonneratia alba, and most of cytotoxic active fungi strains were isolated from mangrove plant Heritiera littoralis.
