Fermentation of biomass-generated producer gas to ethanol

Biotechnology and Bioengineering, 2004
AbstractThe development of low‐cost, sustainable, and renewable energy sources has been a major focus since the 1970s. Fuel‐grade ethanol is one energy source that has great potential for being generated from biomass. The demonstration of the fermentation of biomass‐generated producer gas to ethanol is the major focus of this article in addition to ...

Gas controlled hydrogen fermentation

Bioresource Technology, 2012
Acidogenic fermentation is an anaerobic process of double purpose, while treating organic residues it produces chemical compounds, such as hydrogen, ethanol and organic acids. Therefore, acidogenic fermentation arises as an attractive biotechnology process towards the biorefinery concept.

Gas transfer in microgravity fermentations

Acta Astronautica, 1986
Fermentations performed under microgravity conditions may be used in future long duration space missions for recycling expendable life support materials. These fermentations will differ from similar fermentations performed at one gravity in the manner in which gas transfer in the fermentor is carried out.

Bacterial synthesis gas (syngas) fermentation

Environmental Technology, 2013
Acetogenic bacteria employing the Wood-Ljungdahl pathway can be used as biocatalysts in syngas fermentation for the production ofbiofuels such as ethanol or butanol as well as biocommodities such as acetate, lactate, butyrate, 2,3 butanediol, and acetone.

Fermentation of natural gas with a cyclone column fermenter

Canadian Journal of Microbiology, 1969
A mixed flora, capable of using natural gas as a carbon substrate, was derived from a laboratory sewage sludge. Fermentations in a cyclone column fermenter, on a 1:1 natural gas/air mixture, resulted in a doubling time of 4.6 h and production of 0.065 mg dry cell mass per square centimeter interfacial area per hour.
