beer beats red tide?

RAN ACROSS this cool snippet on Moldy Chum this week, about scientists turning to beer making leftovers to beat the toxic red tide blooms.

 those experiments show spent brewing material — the grain leftover in the process of brewing beer — could contain molecules called flavonoids that stunt the growth of red tide algae blooms.

“And we saw very promising results,” Lovko said. “So, basically that Karenia brevis was dead within 24 hours.”

Mote says the same barley idea has been used successfully to control blue-green algae in freshwater lakes, so why not try it on red tide?
