The sustainable production of solvents from above ground carbon is highly desired. Several
clostridia naturally produce solvents and use a variety of renewable and waste-derived …

Conspectus The price for renewable electricity is rapidly decreasing, and the availability of
such energy is expected to increase in the coming years. This is a welcomed outcome …

Mass transfer limitations in syngas fermentation processes are mostly attributed to poor
solubility of CO and H 2 in water. Despite these assumed limitations, a syngas fermentation …

Background Ethanol production through fermentation of gas mixtures containing CO, CO 2
and H 2 has just started operating at commercial scale. However, quantitative schemes for …

Biogas production from anaerobic digestion is a well-established bioprocess for energy
generation, nutrient recovery, and valorisation of waste resources. Typical biogas contains …

In this work, a model was developed to predict the performance of a bubble column reactor
for syngas fermentation and the subsequent recovery of anhydrous ethanol. The model was …

Highlights•Analytical tools and metabolic models are used routinely in the design gas
fermentation processes.•Acetogen metabolism is controlled largely at metabolite rather than …

Numerical simulation of biological methanation in bubble column reactors is challenging
due to strong coupling between hydrodynamics, mass transfer and bioreaction. A …

Improvements in technology for the production of microbial biomass from natural gas, which
have been gaining importance in recent years, require the development and optimization of …

The demand for carbon capture is increasing over time due to rising CO 2 levels in the
atmosphere. Even though fossil emission could be decreased or even eliminated, there is a …
