Molecular methods, both qualitative and quantitative, have become important in hydrogen-fermenting community analyses to reveal the complexity of the community and to monitor the changes and interactions in the communities during bioprocesses. This r

In this study, quantitative PCR (qPCR) was used to quantify [FeFe]-hydrogenases and subsequently melting curves were analyzed from hydrogen-fermenting, mixed-culture bioreactor samples. Denaturing gradient gel electrophoresis (DGGE) analysis was also

The bacterial communities in three continuously stirred tank reactors co-digesting cow manure with grass silage, oat straw, and sugar beet tops, respectively, were investigated by 16S rRNA gene-based fingerprints and clone libraries. The analyses rev

A quantitative real-time PCR (qrt-PCR) method was developed for quantification of a hydrogen-producing Clostridium butyricum strain. The strain was the main hydrogen producer in a mixed culture bioreactor that was operated on a continuous-flow mode f

Fermentations can be used to produce sustainable energy carriers, such as hydrogen and ethanol (EtOH), from biomass or organic waste materials. The aim of this research was to prospect efficient H2- and EtOH-producing thermophilic microorganisms deri
