... communities or are used for fermentation. Fermentative microorganisms disproportionate the organic molecules into a narrow range of volatile organic acids, such as acetate, formate, propionate, and butyrate, plus H 2 and CO 2 . The products of hydrolysis and fermentation provide substrates for respiring...

... concentrations and abundances of individual species of carboxylic acids vary widely, and only a few of the simple monofunctional and difunctional groups were identified in each study. Typically, monofunctional carboxylic acids (formic, acetic, propionic, butyric, and valeric) reach 5000 ppm, whereas difunctional...

... ). Water-bearing sands, with the exception of sand 8, are high in both ammonium and Br. Ammonium shows a strong positive relationship with Br ( Figure 12 ), suggesting that its origin is related to the origin of the more saline, evaporite waters. The reason for higher concentrations of ammonium in the more...

... performed experiments with 15 N tracers and discovered that ammonium was oxidised anaerobically by anammox bacteria ( Kuypers et al ., 2003 ). This inspired us to do similar studies at continental margins in the South Atlantic and Pacific Oceans where anammox was indeed also found to be a major sink...
