Aquaspirillum

Aquaspirillum is a genus of gram-negative bacteria belonging to the phylum Proteobacteria. These microorganisms are typically found in aquatic environments, including freshwater and saltwater. They are characterized by their spiral or helical shape, which gives them their name. Aquaspirillum species are often motile, using flagella to propel themselves through their surroundings.

These bacteria are microaerophilic, meaning they require a low concentration of oxygen to grow. They are chemoorganotrophs, deriving energy from organic compounds. Their metabolism can vary, with some species capable of utilizing various carbon sources. Aquaspirillum plays a role in nutrient cycling within aquatic ecosystems.

Some species within the Aquaspirillum genus have been studied for their potential to degrade pollutants, suggesting a role in bioremediation. However, they are not typically associated with significant human diseases. Research into Aquaspirillum continues to explore their ecological functions and potential applications. Their characteristic morphology and aquatic habitat are key identifiers for this bacterial group.
