Scytonema hofmanni, a filamentous freshwater cyanobacterium (blue-green alga), produces secondary metabolites which inhibit the growth of other cyanobacteria and green algae. A rapid, qualitative assay for this inhibition has been developed with Synechococcus as the test organism. This assay procedure has led to the isolation and characterization of an antibiotic (named cyanobacterin) from Scytonema. The antibiotic has a molecular weight of 430 and an empirical formula of C23H23O6Cl and contains a gamma-lactone and a chlorinated aromatic nucleus. It inhibits the growth of various algae but has limited effect on nonphotosynthetic bacteria or protozoans and thus may have potential use as a specific algicide.
霍氏伪枝藻是一种丝状淡水蓝细菌（蓝绿藻），能产生抑制其他蓝细菌和绿藻生长的次生代谢产物。已开发出一种以聚球藻为测试生物的快速定性抑制测定法。该测定程序已导致从霍氏伪枝藻中分离并鉴定出一种抗生素（命名为蓝藻素）。这种抗生素的分子量为430，经验式为C₂₃H₂₃O₆Cl，含有一个γ-内酯和一个氯化芳环。它能抑制多种藻类的生长，但对非光合细菌或原生动物的作用有限，因此可能有作为特定杀藻剂的潜在用途。
