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

The name Acidisphaera derives from:
New Latin noun acidum (from Latin adjective acidus, sour), an acid; Latin feminine gender noun sphaera, a ball, globe, sphere; New Latin feminine gender noun Acidisphaera, acid (-requiring) coccoid microorganism.
