Microbiology of synthesis gas fermentation for biofuel production
Current Opinion in Biotechnology, 2007A significant portion of biomass sources like straw and wood is poorly degradable and cannot be converted to biofuels by microorganisms. The gasification of this waste material to produce synthesis gas (or syngas) could offer a solution to this problem, as microorganisms that convert CO and H2) (the essential components of syngas) to multicarbon ...

Abstract Almost any microbial process involves the consumption or evolution of gases, and vent-gas analysis therefore provides a convenient means to monitor microbial activity. In contrast to other monitoring techniques for which the culture medium must be placed in direct contact with a sampling device or probe, vent-gas analysis ...

Reactor Design Issues for Synthesis‐Gas Fermentations
Biotechnology Progress, 1999AbstractSynthesis gas is readily obtained by gasifying coal, oil, biomass, or waste organics and represents an abundant, potentially inexpensive, feedstock for bioprocessing. The primary components of synthesis gas, carbon monoxide and hydrogen, can be converted into methane, organic acids, and alcohols via anaerobic fermentations.

Fermentation of biomass‐generated producer gas to ethanol
Biotechnology and Bioengineering, 2004AbstractThe 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 ...

Human intestinal gas measurement systems: in vitro fermentation and gas capsules
Trends in Biotechnology, 2015The biological and clinical significance of the human gut microbiome is currently attracting worldwide attention. While rRNA and DNA technologies led to a quantum leap in our understanding of the numbers and types of gut microorganisms, much less is known about these microorganisms' activity in situ and in real time.

DETERMINATION OF OXYGEN UTILIZATION IN FERMENTATIONS BY GAS CHROMATOGRAPHY
Canadian Journal of Microbiology, 1962Dissolved oxygen in fermenting media is determined by withdrawing a sample using a hypodermic syringe containing a germicide. Gases are extracted from the sample under vacuum and analyzed by gas chromatography. Oxygen utilization is estimated by analysis of the exit gases using a similar analytical technique.

Gas-Forming Citrate-Fermentation by Lactococci
Dairy industryIn milk processing, effective microbiological control depends on the correct choice of lactic acid bacteria in the microflora of bacterial starters. However, polyspecific starter consortia of acid-forming and aroma-forming lactococci still have no distinct criteria.

Membrane gas sensors for fermentation monitoring
Journal of Fermentation Technology, 1987Abstract Results from studies of membrane gas sensors are presented to show their general applicability to fermentation monitoring of volatiles, such as alcohols, organic acids, and aldehydes under various process and reactor conditions. Mainly the silicone tubing methods is described, with examples from ethanolic fermentation.
