Objective To isolate fungi from sea sediment and sea water samples collected from the neritic environment in Qingdao, screen their antitumor activity and study on their fermentation condition. Methods The antitumor activity was assayed by flow cytometry in mouse tsFT210 cells. Results The medium added penicillin and streptomycin possesses good selectivity. 207 strains of fungi were isolated and among them, 19 strains showed antitumor activity, and one fungus(Z 83200)pocesses strong cell apoptosis inducing activity.
