Most mixed culture studies on the allelopathic interactions between toxic and nontoxic cyanobacteria with phytoplankton species rarely investigate the role of microcystins (MC) production and regulation in the course of the studies. This study investigated the interactions between intact cells of toxic (Microcystis aeruginosa (Kützing) Kützing) and nontoxic(More)
Cylindrospermopsis raciborskii ITEP-A1 is a saxitoxin-producing cyanobacterium. We report the draft genome sequence of ITEP-A1, which comprised 195 contigs that were assembled with SPAdes and annotated with Rapid Annotation using Subsystem Technology. The identified genome sequence had 3,605,836 bp, 40.1% G+C, and predicted 3,553 coding sequences (including(More)
The effect of saxitoxins (STX) on phytoplankton species is poorly understood. To date, no correlation between STX concentrations and phytoplankton physiology has been reported. We investigated the effect of STX (STX+, 0.5–10 μg L −1 total STX) and non-STX (STX−, 0.5–10 μg L −1 total STX biomass equivalent) extracts of Cylindrospermopsis raciborskii on(More)
