Growth and anatoxin-a production of Microcoleus (Cyanobacteria) strains from streams in California, USA.

ABSTRACT: Benthic cyanobacterial proliferations are an emerging concern globally due to their potential for toxin production and subsequent negative environmental and health impacts. Microcoleus is a common mat-forming genus reported to produce potent neurotoxin, anatoxin-a, ingestion of which has been associated with animal mortalities. Six different unialgal monoclonal strains of Microcoleus were isolated from streams in California and grown in batch culture for 49 days. The four toxic strains were identified using a polyphasic approach as belonging to the species Microcoleus anatoxicus, which expands its known distribution throughout the Klamath River and Rock Creek watersheds in northern California. The non-toxic strains from the Eel River belonged to Microcoleus sp. 1. Maximum toxin production
