Arhodomonas aquaeolei
species of bacterium
Arhodomonas aquaeolei is a species of the bacterial genus Arhodomonas noted for its ability to grow in an environment of high salinity. It is an aerobic, oval rod-shaped, gram-negative bacterium. It is motile by means a single polar flagellum.
A. aquaeolei is among the most halophilic organisms known. The temperature range for the growth of this bacteria is between 20 °C and 45 °C, with optimal growth at 37 °C and it requires specifically sodium chloride (NaCl) for its growth. (Other salts do not promote growth of A. aquaeolei.) Growth occurred at NaCl concentrations between 6% and 20% in a Campylobacter medium. Although A. aquaeolei is most closely related to purple sulfur bacteria, it does not share those organisms' phototrophic traits. A. aquaeolei has been shown to degrade phenol and phenol based compounds, indicating possible industrial uses. A. aquaeolei causes no known diseases.

“Arhodomonas aquaeolei” enters the record as species of bacterium. Crown Archives preserves that source wording while asking what Arhodomonas, aquaeolei and species can confirm, complicate or overturn.
Why this record matters
“Arhodomonas aquaeolei” is worth following because a concise public description often conceals a longer documentary argument. Here, Arhodomonas, aquaeolei and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 30, 2025. The linked authority identifier is Q20685937. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1993.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
