Genomic characterization of coexisting anatoxin-producing and non-toxigenic Microcoleus subspecies in benthic mats from the Wolastoq, New Brunswick, Canada

Cecilio Valadez-Cano et al.

Summary: The presence of toxigenic benthic cyanobacteria in riverine ecosystems is a global concern. In 2018, the death of three dogs in Canada was linked to anatoxin exposure from benthic microbial mats. DNA sequencing of cyanobacterial isolates from the mat samples revealed that some produced anatoxins while others did not. Genomic comparisons showed that toxigenic and non-toxigenic Microcoleus subspecies coexisted with differences in the presence/absence of the anatoxin-a biosynthesis cluster.

Acute toxicity of dihydroanatoxin-a from Microcoleus autumnalis in comparison to anatoxin-a

Jonathan Puddick et al.

Summary: Microcoleus autumnalis, a cyanobacterium growing in rivers, produces high concentrations of the neurotoxin dhATX, which has demonstrated high acute toxicity upon ingestion. Further research is needed to assess the environmental impact and health risks associated with this cyanobacterial species.

Trophic triage: a tiered eutrophication vulnerability screening tool for lakes in sparsely monitored regions

L. Johnston et al.

Summary: The study developed a tiered eutrophication vulnerability screening tool for lakes in sparsely monitored regions, which includes a desktop study and water quality sampling program to assess lakes' vulnerability to eutrophication. The tool was demonstrated on lakes in Nova Scotia, Canada, and proved to be effective in identifying lakes vulnerable to eutrophication.

CyanoMetDB, a comprehensive public database of secondary metabolites from cyanobacteria

Martin R. Jones et al.

Summary: CyanoMetDB is a curated database containing 2010 cyanobacterial metabolites, enabling research into their occurrence, functions, and toxicological risks. It facilitates the detection and dereplication of known cyanobacterial toxins, identification of novel natural products, research on biosynthesis of cyanobacterial metabolites, and investigation of their abundance, persistence, and toxicity.
