The use of a benign fast-growing cyanobacterial species to control microcystin synthesis from <i>Microcystis aeruginosa</i>.

ABSTRACT:

Introduction

Microcystis aeruginosa (M. aeruginosa), one of the most prevalent blue-green algae in aquatic environments, produces microcystin by causing harmful algal blooms (HAB). This study investigated the combined effects of nutrients and cyanobacterial subpopulation competition on synthesizing microcystin-LR.

Method

In varied nitrogen and phosphorus concentrations, cyanobacterial coculture, and algicidal DCMU presence, the growth was monitored by optical density analysis or microscopic counting, and the microcystin production was analyzed using high-performance liquid chromatography-UV. Furthermore, growth and toxin production were predicted using MATLAB.

Results and discussion

First, coculturing with a fast-growing cyanobacterium Synechococcus elon
