Allochromatium phaeobacterium
Template:Short description Template:Taxobox
Allochromatium phaeobacterium (A. phaeobacterium) is a phototrophic and rod-shaped purple sulfur bacterium from the genus of Allochromatium which has been isolated from brackish water in Bheemli, Visakhapatnam, India.[1][2][3][4][5]
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 carotenoids.[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]
