Dark fermentation (DF) is a promising technology for biohydrogen production. Low efficiency
of biohydrogen production is a bottleneck of the scale-up prospects for DF. Additives have …

During enterobacterial mixed-acid fermentation, formate is generated from pyruvate by the
glycyl-radical enzyme pyruvate formate-lyase (PflB). In Escherichia coli, especially at low …

Escherichia coli anaerobically ferment glucose and perform proton/potassium exchange at
pH 7.5. The role of hyf (hydrogenase 4) subunits (HyfBDF) in sensing different …

Carboxylic acids (CAs) are important organic compounds that participate in various cellular
metabolic pathways. Since maintenance of intracellular CA concentration is vital for cell …

Although Escherichia coli has four hydrogenases, their definite roles in fermentation are still
not clear. In this study, all the operon deletion mutants of E. coli hydrogenases (∆ hya,∆ …

The Hyf-type formate hydrogen lyase (FHL) complex was first proposed based on sequence
comparisons in Escherichia coli in 1997 (Andrews et al. in Microbiology 143: 3633–3647 …

Escherichia coli anaerobically ferment glucose and perform proton/potassium exchange at
pH 7.5. The role of hyf (hydrogenase 4) subunits (HyfBDF) in sensing different …

Hydrogen fuel offers a significant alternative to fossil fuels in the context of a rising carbon
footprint in the atmosphere and declining fossil fuel resources. H2 is the only gas fuel, which …

Concerns about exhaustion of natural resources and global warming have led to increasing
attention to clean and renewable energy. Here, biohydrogen (H2) is a very attractive …

Meanwhile, a year has passed since the untimely death of Armen Trchounian, Professor of
Biochemistry, Microbiology and Biotechnology at Yerevan State University, Armenia, from …
