| competitive oxidation of volatile fatty acids by sulfate- and nitrate-reducing bacteria from an oil field in argentina. | acetate, propionate, and butyrate, collectively referred to as volatile fatty acids (vfa), are considered among the most important electron donors for sulfate-reducing bacteria (srb) and heterotrophic nitrate-reducing bacteria (hnrb) in oil fields. samples obtained from a field in the neuquén basin, western argentina, had significant activity of mesophilic srb, hnrb, and nitrate-reducing, sulfide-oxidizing bacteria (nr-sob). in microcosms, containing vfa (3 mm each) and excess sulfate, srb first ... | 2008 | 18502934 |
