A cohesive strain cluster causes benthic cyanotoxic blooms in rivers worldwide.

Over the last two decades, proliferations of benthic cyanobacteria producing derivatives of anatoxin-a have been reported in rivers worldwide. Here, we follow up on such a toxigenic event happening in the Areuse river in Switzerland and investigate the diversity and genomics of major bloom-forming riverine benthic cyanobacteria. We show, using 16S rRNA-based community profiling, that benthic communities are dominated by Oscillatoriales.

Complete genome sequence of strain Ins1, a spore-forming filamentous bacterium isolated from a deep geothermal reservoir.

We report the complete genome sequence of strain Ins1, a gram-positive filamentous spore-forming bacterium, isolated from deep geothermal fluids used for electricity production. This is the first complete (circular) genome assigned to the species .
