<p>At least one algae-produced, substantially pure chemical compound with biocidal activity has been isolated from a blue-green algal (Cyanobacteria) toxin, preferably Scytonema toxin. This biocide appears to be one of the first of its class, since very little is now known regarding algal toxins and any biocides (including any antibiotics) they may contain. A biocide of this invention has activity against harmful blue-green algae such as Anabaena and can be used as, among other things, an algicide with minimal undesirable effects upon the environment of use (e.g. lakes, streams, water supplies, swimming pools, etc.). An ether-soluble, nonsteroidal, anisole-containing biocide of this invention appears to have a molecular weight of 430 or 431, a melting point or range within the range of about 48 DEG to about 55 DEG C., and the empirical formula C23H23O6Cl. Other groups in the molecule besides the anisole appear to include a saturated gamma-lactone, an aliphatic OH, a methylene bridge, a chlorobenzene ring, and an isopropyl substituent (probably attached to the gamma-lactone) in an asymmetric environment. The compound can be stored in or crystallized from diethyl ether and blended with the usual pharmaceutical extenders.</p> |
