摘　　要：The biological hydrogen generating from fermentation of low-cost lignocellulosic feedstocks by hydrogen-producing bacteria has attracted many attentions in recent years. In the present investigation, ten hydrogen-producing bacteria were newly isolated from the intestine of wild common carp (</span><span style="font-family:Verdana;"><i>Cyprinus carpio</i></span><span style="font-family:Verdana;"> L.), and identified belonging to the genera of </span><i><span style="font-family:Verdana;">Enterobacter</span></i><span style="font-family:Verdana;"> and </span><i><span style="font-family:Verdana;">Klebsiella</span></i><span style="font-family:Verdana;"> based on analysis of the 16S rDNA gene sequence and examination of the physiological and biochemical characteristics.
