Nitrogen pulse drives a prolonged microcystin event by increasing the proportion of toxigenic Microcystis genotypes.

Abstract excerpt

Microcystins (MCs) pose a major risk to drinking water safety, yet their production drivers remain poorly understood. We conducted a year-long, high-frequency monitoring program in a large subtropical reservoir to identify environmental triggers and regulatory mechanisms of Microcystis blooms and toxin production. Microcystis blooms occurred in May and July, followed by a six-month MC contamination event from...
