Identification and comparison of biology characteristics among three novel fermentative hydrogen producing bacteria

The morphology,physiology and biochemistry characteristics of three fermentative hydrogen producing bacteria were compared.Furthermore,their phylogenetic tree derived from the full-length 16S rDNA sequence was analyzed,their hydrogen production and their liquid products were determined.It was suggested that these three bacteria belong to a new fermentative H2-producing bacterium genus.Their liquid products included alcohol and acetic acid mainly.Under the given culture conditions,high hydrogen production could be achieved.At the same time some common biology characteristics of these bacteria were also described.
