Process for the quantification of methane gas bacteria and especially for monitoring the methane gas formation capacity of reactors containing methanogenic bacteria

摘要

The method entails a representative sample of a medium containing the methane gas bacteria being exposed for a maximum of one second to brief irradiation with light of wavelengths from 395 to 440 nm, and the fluorescence excited thereby being determined by flow cytometry. This method makes it possible to determine methane gas bacteria in situ without previous extraction. The method is particularly suitable for use for monitoring and controlling reactors with methanogenic bacteria.
