CyanoVault is a curated collection of cyanobacterial strains, with a specialized focus on thermophilic isolates from Yellowstone National Park geothermal environments.
The repository provides documented strain records, genomic information, cultivation conditions, and laboratory growth data to support research and teaching.
Thermophilic cyanobacteria from geothermal environments are inherently challenging to isolate, cultivate, and maintain under laboratory conditions. Sustained high temperatures impose physiological constraints that affect growth stability and long-term preservation. Consequently, well-documented thermophilic cyanobacterial collections remain limited worldwide.

The platform is supported through the BioNitrogen Economy Research Center (BNERC), funded by the U.S. National Science Foundation EPSCoR E-RISE program.
These organisms harbor heat-stable enzymes, photosynthetic machinery, and regulatory networks that sustain oxygenic photosynthesis under thermal stress, valuable models for high-temperature adaptation and thermotolerant bioprocess design.
CynoVault documents and curates thermophilic isolates from Yellowstone geothermal systems, integrating genomic records, cultivation parameters, and growth performance data for direct comparison across isolates.
The collection grows through active isolation efforts by the CynoVault team, serving as a research platform within BNERC to advance thermophilic nitrogen utilization and high-temperature bioprocess design.

Thermosynechococcus elongatus BP-1 is a thermophilic, unicellular cyanobacterium commonly used as a model organism for oxygenic photosynthesis. It grows optimally at high temperatures (approximately 50-55 °C) and performs efficient light-driven carbon fixation using well-organized photosystems. Because its photosynthetic machinery especially Photosystem I and II is highly stable and well characterized, this organism is widely studied to understand photosynthesis, energy conversion, and thermal adaptation in cyanobacteria.
A thermophilic cyanobacterium capable of nitrogen fixation that can also adapt to growth at temperatures below its optimal range. It is motile via gliding and forms branching filaments. The organism develops gelatinous, cartilaginous, or spongy mats that are dull blue-green to olive-green in color and exhibits a growth rate of approximately 1.5 doublings per day. It shows low tolerance to hydrogen sulfide and produces spores that are resistant to freezing and desiccation.

Step-by-step methodologies for working with thermophilic cyanobacteria
Light microscopy is used to perform a preliminary assessment of the samples. A small aliquot of each sample is prepared as a wet mount on a clean glass slide and observed under a light microscope using 10x and 40x objectives. When required, samples are gently diluted to avoid overcrowding and to improve visibility. No staining is performed in order to preserve natural pigmentation and native cell structures. This protocol enabled rapid visualization of microbial morphology and community structure.
