摘　　要：比较了三株发酵产氢细菌的形态和生理生化特征,分析了它们的16S rDNA序列系统发育关系,并测定了它们的产氢量和液相发酵产物。认为它们同属于一类新的发酵产氢菌属,其液相产物以乙醇和乙酸为主,在一定的培养条件下可获得较高产氢量。此外,对该类细菌的某些共同的生物学特征也作了描述。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.
