Utilization kinetics of volatile fatty acids (acetic, propionic and butyric acids) in mesophilic (35ยฐC) methaneproducing biofilms were investigated in a continuous flow reactor. The mass transfer resistances occurring inside and outside biofilms were tested and minimized during the experiments. By m

โฆ Synopsis
n-Butyrate, n-valerate and n-caproate were more inhibitory towards Methanobacterium byrantii, Methanobacterium formicicum and Methanosarcina barkeri than the corresponding iso-acids. Butyrate caused maximum inhibition irrespective of isomer. Methanobacterium bryantii was more sensitive to inhibition than Methanobacterium formicicum.

The competition between acetate utilizing methane-producing bacteria (MB) and sulfate-reducing bacteria (SRB) was studied in mesophilic (30ยฐC) upflow anaerobic sludge bed (UASB) reactors (upward velocity 1 m h -1 ; pH 8) treating volatile fatty acids and sulfate. The UASB reactors treated a VFA mixt
