Golden Algae Toxin Identified, Detection and Monitoring Tools Developed

Region(s) of Study: U.S. States and Territories / Arizona

Researchers finally identified the main toxic compounds produced byPrymnesium parvum, also known as “golden tide.” A fish-killing algae, this organism had historically affected aquaculture and marine systems worldwide, but now also frequently plagues popular fishing spots in the western United States, such as in Arizona last month.Identifyingthese toxins as well as their primary mode of action allowed researchers from the National Centers for Coastal Ocean Science to develop highly sensitiveanalyticaldetection and monitoring tools.

Using NCCOS’s dedicated Nuclear Magnetic Resonance and chemistry facilities, scientists isolated, purified and structurally characterized the toxins. They alsoidentified the critical role of environmental factors such as metal concentration and water pH that can dramatically alter the organism’s toxicity.
