Abstract
The effects of volatile short chain fatty acids (VFAs) and long-chain fatty acids (LCFAs) on hydrogen consumption were investigated using a mixed anaerobic culture acclimated to glucose. The study was conducted in serum bottles by adding LCFAs (2000 mg l-1 oleic or linoleic acid) and VFAs (0 to 1500 mg l-1 acetate, propionate, or butyrate) to the culture and hydrogen (500 or 1000 mumoles) to the headspace. Overall, the consequence of increasing the VFA concentration in the presence of LCFAs caused an increased inhibition of hydrogen consumption. VFAs were also examined in mixtures. Experiments with similar total VFA concentrations showed similar levels of inhibition in the range studied, though increased total VFA concentration increased inhibition. The effect of incubation time of individual LCFAs and VFAs prior to hydrogen addition was investigated. LCFA and VFA incubation time had a statistically significant effect on hydrogen consumption.Dept. of Civil and Environmental Engineering.
