Acidisphaera is a genus in the phylum Pseudomonadota (Bacteria). The genus contains a single species,[1] namely A. rubrifaciens with the following characteristics:[2]

  • strictly aerobic, light preferred
  • mesophilic
  • acidophilic (3.5–6.0 pH, optima of 4.5-5.0)
  • bacteriochlorophyll (BChl a) and carotenoids production (salmon-pink colonies), the former contained zinc if grown in the presence of 1 mM zinc sulfate.
  • chemo-organotrophic
  • Gram-negative, as expected from a proteobacterium
  • isolated from acidic hot springs and mine drainage
  • non-motile
  • cocci / coccobacilli
  • Part of the major acidophilic alphaproteobacterial group with the genera Acidiphilium and Rhodopila

Etymology

edit

The name Acidisphaera derives from:
Neo-Latin noun acidum (from Latin adjective acidus, sour), an acid; Latin feminine gender noun sphaera, a ball, globe, sphere; Neo-Latin feminine gender noun Acidisphaera, acid (-requiring) coccoid microorganism.[1]
While the specific epithet rubrifaciens comes from the Latin adjective ruber -bra -brum, red; Latin v. facio, to make; Neo-Latin participle adjective rubrifaciens, red-producing.)[1]
