摘要：

Nodularia harveyana, a dinitrogen-fixing cyanobacterial isolate from the Mediteranean Sea, grown in an outdoor photobioreactor, was assayed for its bioactive compounds. The active substance(s) were lypophilic and showed strong allelopathic actvity against other axenic cyanobacteria, antibiotic activity against Gram-positive pathogenic bacteria and antifungal activity against two plant pathogens. The extracts were toxic (LC50 at 30 mu L) for grazers such as a rotifer (Brachionus calyciflorus) and a crustacean (Thamnocephalus platyurus).
