Automatic gas meter for laboratory fermenters
Biotechnology Techniques, 1995A versatile, cheap and automated system is designed for the measurement of small gas flows produced in laboratory-scale fermentation processes. An automatic sampling device for programmed times is linked to the flow meter. The displacement of a liquid by the gas being measured is the principle on which both the meter and the sampling device are based ...

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.

Controlled gas environments in industrial fermentations
Enzyme and Microbial Technology, 1980Abstract The gas environment is of major importance in controlling aerobic fermentation processes for the manufacture of microbial products. Oxygen and carbon dioxide levels in gas-liquid equilibria affect productivity and energy consumption in such processes and appear to be implicated in the regulation of microbial metabolism.

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.
