Quantitative Detection of Syntrophic Fatty Acid-degrading Bacterial Communities in Methanogenic Environments [PDF]

open access: yes, 2015
In methanogenic habitats, volatile fatty acids (VFA), such as propionate and butyrate, are major intermediates in organic matter degradation. VFA are further metabolized to H2, acetate and CO2 by syntrophic fatty acid-degrading bacteria (SFAB) in ...
