A novel anaerobic bacteria strain was used for the production of biohydrogen with food wastes. Among a few hydrogen producing strains which were isolated from natural environment, one of the isolate, designated FH2072, exhibited the highest hydrogen production. This isolate was identified to belong to Clostridium aurantibutyricum using 16S rDNA analysis. Hydrogen production by C. aurantibutyricum FH2072 with a dried food waste product (FWP), obtained from EService Corp., was surveyed in batch culture tests. C. aurantibutyricum FH2072 produced H2 using the FWP under anaerobic conditions regardless of enzyme hydrolysis of FWP. In a medium containing 3% (w/v) hydrolyzed FWP, C. aurantibutyricum FH2072 exhibited the maximum hydrogen production rate of 56 ml H2 l-1h-1 and the total hydrogen production of 1848 ml H2 l-1.
