Acidobacterium sp. Ellin345 is a member of the subdivision 1 (sensu Hugenholtz et al. 1998) of the phylum Acidobacteria. It was isolated from soil of an Australian pasture (Sait et al. 2002).

The bacterium is a gram-negative, highly capsulated, aerobic heterotroph that grows with a range of sugars, sugar polymers, and some organic acids. This group is widely distributed in soils, and members makes up to 14% of soil bacterial communities (mean = 3.3%). Isolate Ellin345 belongs to a candidate order-level grouping phylogenetically distinct (Sait et al. 2002) from the order Acidobacteriales that contains Acidobacterium capsulatum, the type species of the phylum Acidobacteria. Acidobacterium capsulatum was isolated from an acid-mine drainage impacted site (Kishimoto et al. 1991), but Ellin345 is an isolate from soil.
