Halanaerobium hydrogeninformans
is alkaliphilic bacterium that capable of biohydrogen production at ( pH 11 and 7% (w/v)  sodium chloride salts ) and 35˚c. , it commonly found in haloalkaline lakes.

H.hydrogeninformans was first discovered by Dr.Melanie Mormile, professor of biological sciences at Missouri university for science and technology and her team, from the  soap lake, Washington.

Microbiology
Halanaerobium hydrogeninformans is obligatory anaerobic, Gram negative ,non motile , non-sporulating , elongated rod bacterium It belongs to phylum Firmicutes , it can ferment a variety of 5- and 6-carbon sugars derived from hemicelluloses and cellulose including cellobiose , and forms the end products hydrogen, acetate, and  formate

Genome structure
The H.hydrogeniformans genome sequence was determined through a combination of Illumina and 454 technologies. The total genome size is 2,613,116 bp, with final assembly based on 52.2 Mb of 454 draft data providing an average 21.5_genome coverage and 463 Mb of Illumina draft data providing an average 178_ genome coverage. The genome is 33.1% G+C and contains 2,295 candidate protein-encoding gene models. The genome contains four separate rRNA operons, each containing a 5S, a 16S, and a 23S rRNA gene, with 99.9 to 100% identity between 16S rRNA genes.

Applications
As the price of fossil fuels increases and reserves diminish, biofuel production is seen as a viable contribution to current. as well as future energy demands, Halanaerobium hydrogeninformans can use several pure sugars for hydrogen production, Hence, this bacterium can potentially increase the efficiency and efficacy of biohydrogen production from renewable biomass resources.
