A. phaeobacterium was first isolated from anoxic sediment in 2007, and isolated on a modified Bielbl and Pfennig medium.[5]

Description

A. phaeobacterium is a rod-shaped, gram-negative species of bacteria. This species appears brown in color, and is 1.0-1.5x2.0-4.0 in length. A. phaeobacterium is motile and reproduces through binary fission.[5] It has been observed growing photoautotrophically, photolithoautotrophically, photolithotrophically, and photoorganoheterotrophically.[5]

Absoprtion spectra has confirmed photoreceptors bacteriochlorophyll α, rhodopinals, and caretenoids.[5]

Genome

A. phaeobacterium has been partially sequenced through 16s rRNA gene sequencing with a sequence of approximately 1400 base pairs. The G/C content is 59.8%.[5] Based on phylogenetic analysis from this 16s sequence, Allochromatium phaeobacterium is considered morphologically and physiologically distinct from others in the Allochromatium genus.[5]
