Important issues in the microbiology of biological reactors include bacterial composition and cell counts of bacterial communities. Because oligonucleotide probes targeting a particular phyletic group are available for studying hydrogen fermentation, fluorescence in situ hybridization (FISH) could be an attractive research technique. Although we reported the importance of the Megasphaera spp. for a simple hydrogen fermentation system, fundamental information like population and composition remains unclear. Thus, here, we established the use of Megasphaera-specific oligonucleotide Mega-X for FISH and the optimum conditions for rapid single-cell level identification. The culture isolated from a simple hydrogen fermentation process was identified as Megasphaera elsdenii and was shown to be significantly dominant (30%-58% of the microflora) by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and FISH. The combination of Megasphaera-specific PCR-RFLP and FISH is likely to become an important methodology for understanding the global distribution and behaviour of Megasphaera spp. in the environment.
